According to Cailian News, at the Huawei Developers Conference held today, HarmonyOS NEXT launched a Beta version for developers, and Huawei Mate 60 series, Mate X5, MatePad Pro 13.2-inch and other devices were upgraded on the same day. It is expected that the Beta upgrade will be launched for consumers in August 2024, and the official version will be launched with the launch of Mate70 series in the fourth quarter.
In addition, Huawei Cloud released Pangu Model 5.0 at the meeting, including different parameter scales such as one billion, ten billion, one hundred billion and one trillion.
It is worth mentioning that Huawei Cloud also released a large model of Pangu’s intelligent body, and demonstrated the Kuafu humanoid robot in cooperation with Leju Robot on the spot, and completed interactive demonstrations such as object identification, question-and-answer interaction, high-five, and water delivery.
Pure blood HarmonyOS has achieved full-stack self-research
At the Huawei Developer Conference, Yu Chengdong, managing director of Huawei and chairman of terminal BG, said,Pure blood HarmonyOS realizes full-stack self-research from the inside out.. "HarmonyOS is a full-scenario intelligent operating system based on Open Harmony, which is an autonomous and controllable operating system from China."
At present,There are more than 900 million ecological devices in HarmonyOS, and the number of Harmony OS developers has reached 2.54 million.. Yu Chengdong revealed that shipments of Pura 70 series increased by 68% from January to May in 2014, and shipments of flagship mobile phones increased by 72%.
Up to now, the first 5,000 APPs have been added to HarmonyOS Eco, and 1,500+apps have been put on the shelves. Yu Chengdong specially thanked mainstream app manufacturers such as Tik Tok, Meituan and Nail.
At the meeting, mPaaS, an ant math department, also announced the progress of three-way co-construction of HarmonyOS Ecology: more than 200 apps including Huaxia Bank, Guangfa Bank, PetroChina and China Mobile started the HarmonyOS development test. It is reported that Ant mPaaS is a mobile development platform under several branches, which has been fully adapted to more than 100 SDK in HarmonyOS.
The science and technology innovation board Journal learned that Zhongtai Securities also pushed its mobile App, Taiqi Futong, to complete the first batch of native application development in HarmonyOS, and launched it in the "HarmonyOS Pioneer Application Zone" in Huawei’s application market. According to the person in charge of the Zhongtai Qifutong team, the post-construction of the HarmonyOS Edition project will realize the optimization of four functions, including the coverage of basic services, the customization of personalized functions of customers, the integrated display of account information and the deep adaptation of HarmonyOS’s characteristic functions.
However, some people related to the industrial chain expressed concern about the ecological construction after HarmonyOS completely separated from Android. “Some overseas apps may not work on pure blood HarmonyOS, including some minority apps. After completely leaving Android, it is impossible for all apps to support HarmonyOS.So there is still a long way to go. However, it remains to be seen how HarmonyOS will advance overseas and how well it will be accepted by consumers. "
Pangu Big Model 5.0 was released to show the interaction of humanoid robots.
Pangu Big Model 5.0 was released today, including models with different parameters and specifications. Among them, Pangu E series with billions of parameters can support smart applications such as mobile phones and PCs. Pangu P series with tens of billions of parameters is suitable for reasoning scenarios with low delay and low cost; Pangu series with hundreds of billions of parameters is suitable for dealing with complex reasoning and can become the base of general enterprise model; Pangu S series super-large model with trillions of parameters is a super-large model to deal with cross-domain multi-tasks

Zhang Pingan said that apart from humanoid robots, Pangu’s intelligent model can also be used for various forms of industrial robots and service robots, so that they can help human beings to engage in dangerous and arduous work.
"As everyone expected, let AI robots help us to wash clothes, cook and sweep the floor, so that we can have more time to read books, write poems and paint." Zhang Pingan said.
Original title:Huawei Pure Blood HarmonyOS is here! It is expected to be officially commercialized in the fourth quarter
In the compact car market, Nissan and Volkswagen have always been the hot models concerned by consumers. These two cars have their own advantages, both in design, interior style, power performance and market reputation. So, for you who are considering buying an oil car, how should you choose? This paper will make a comparative analysis of Sylphy and LaVida from many angles to help you make wise decisions.
Price and car purchase cost
Price is undoubtedly one of the most concerned factors when consumers buy a car. According to the latest market data, the price range of 2024 Nissan Sylphy is 68.6-13.49 million yuan, while the price range of 2024 Volkswagen LaVida is 49.0-99.9 million yuan. From the price range, LaVida’s starting price is lower, which is more attractive to consumers with limited budget. In particular, the price of LaVida’s entry-level models has dropped to more than 60,000 yuan, which is very rare in the same class. However, it is worth noting that Sylphy often has a large preferential margin in actual sales, and some dealers even offer preferential loan activities and trade-in subsidies, which further reduces its actual car purchase cost.
Appearance design and style
In terms of design, Sylphy and LaVida both show their own unique styles. Xuanyi continues the classic elements of family style, with full machine cover, compact body lines and a large area of blackened net, creating a strong sense of muscle and sports. LaVida, on the other hand, uses a straight waterfall chrome trim and a sharp headlight group, which is simple without losing the sense of strength. On the side of the car body, LaVida’s waistline runs through the car body, adding a sense of movement to the whole car. In the rear part, both cars adopt the design language of their own brands, showing different visual effects. Judging from the overall feeling of appearance, Xuanyi is younger and more sporty, suitable for young consumers who pursue fashion and dynamic; LaVida, on the other hand, is more stable and atmospheric, suitable for home users who pay attention to quality and practicality.
Interior design and configuration
Entering the car, Sylphy and LaVida also have their own advantages in interior design. Sylphy’s interior is similar to the current model. The center console and door panel are wrapped in large leather, equipped with self-luminous 7-inch instrument panel, 12.3-inch central control screen and three steering wheels. The overall style is biased towards home use. LaVida, on the other hand, adopts a symmetrical layout style, with clear functional divisions and convenient operation. Some areas are wrapped with soft materials, matched with stitching and punching technology, which improves the texture of the interior. In addition, LaVida also comes standard with an 8-inch full LCD instrument and an 8-inch central control panel (10.25 inches and 12 inches for high-profile models), and is equipped with MOS intelligent interconnection system and other functions. LaVida is slightly superior in the sense of luxury and technology in the interior. However, Sylphy’s seat design is more generous and comfortable, providing passengers with a better ride experience.
Power performance and fuel economy
In terms of power, Sylphy is equipped with a 1.6L naturally aspirated engine with a maximum power of 90kW(122 HP) and a maximum torque of 155N·m, matching the CVT continuously variable gearbox. LaVida offers 1.5L and 1.5T power versions for consumers to choose from. Among them, the 1.5L naturally aspirated engine has a maximum power of 81kW(110 HP) and a peak torque of 141N·m, matching a 6-speed automatic manual transmission. The 1.5T engine has higher power output. From the perspective of dynamic performance, Sylphy’s accelerated ride comfort and fuel economy are more suitable for urban commuting and home transportation; LaVida’s 1.5T version is more suitable for consumers who have higher requirements for power. However, it should be noted that the 1.5L version of LaVida is slightly inferior to the 1.6L version of Sylphy in power. In terms of fuel economy, both cars have performed quite well. The comprehensive fuel consumption of the Ministry of Industry and Information Technology of Sylphy is between 4.9 and 6.1L/100 km, while the comprehensive fuel consumption of the WLTC of LaVida is only 5.92L/100km(1.5L version).
Market feedback and word of mouth
Sylphy and LaVida, as popular models in the market, have received extensive attention and praise. Many car owners think that Xuanyi’s exterior design is fashionable and dynamic, the interior is comfortable and practical, and the fuel economy is excellent; LaVida, on the other hand, has won the trust of consumers with its stable and atmospheric appearance, exquisite craftsmanship and reliable quality. In addition, the two models have also performed well in terms of safety, and they are equipped with a number of active and passive safety configurations to ensure the safety of drivers and passengers. According to the statistics of the User Behavior Research Institute of Cheping.com, Sylphy won the title of the best word-of-mouth vehicle in the 2023 [Car Review List], and its positive word-of-mouth index reached 9052 points. LaVida also won a good reputation in the market with its balanced performance and excellent cost performance.
In 2015, the bright spots of Internet development in China appeared frequently. This aspect benefited from the rich accumulation of talents, users, products, companies, capital and concepts after 20 years of development of the Internet in China, which ushered in a period of rapid development from a network power to a network power; On the other hand, thanks to the top-level design of the country and the active participation of the whole society, the "internet plus" has risen to the national strategic level, promoting mass entrepreneurship and innovation, and the Internet has become an indispensable part of China’s infrastructure construction, scientific and technological progress, economic transformation, social development, national governance and even international exchanges and cooperation.
Highlights of Internet Development in China in 2015
The 13th Five-Year Plan proposal adopted by the Fifth Plenary Session of the 18th CPC Central Committee emphasizes the implementation of the strategy of strengthening the country through network, the implementation of the "internet plus" action plan, the development of sharing economy and the implementation of the national big data strategy. The national top-level design has greatly promoted the Internet to penetrate all aspects of China’s economic, social and cultural development.
(A) the national strategic level
1. "internet plus" has risen to a national strategy and built a new ecology of economic development.
In March, the government work report proposed to formulate the "internet plus" action plan, and in June, the the State Council executive meeting adopted the "internet plus Action Guiding Opinions". In 2015, eight ministries and bureaus, including the National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Communications, the Ministry of Agriculture, the Ministry of Commerce, the Health Planning Commission, the Tourism Bureau and the Energy Bureau, issued the "internet plus", among which the Ministry of Commerce has issued the first ministerial-level action plan, and the Ministry of Industry and Information Technology issued the "internet plus" three-year action plan. Subsequently, local versions of action plans were launched one after another. Fujian, Jiangxi, Jiangsu, Guangdong, Sichuan, Hunan, Henan and other provinces will definitely formulate their own Internet action plans. More than 20 provincial local governments across the country have signed strategic cooperation agreements with major Internet companies to carry out comprehensive and in-depth cooperation in cloud computing, big data, smart city construction, Internet public services, e-commerce and Internet finance.
"internet plus" related forums and conferences are getting more and more popular. From government to enterprises to individuals, people are exploring how to use the power of the Internet to achieve efficiency improvement, industrial upgrading and innovation and entrepreneurship. Internet plus Finance, inclusive finance in the Internet Age; Retail in internet plus, achieving e-commerce; Internet+education to achieve universal online education; Internet plus Life Service, Achieving O2O. The "mass entrepreneurship and innovation" promoted by the Internet are also concentrated in these areas. The future Internet will be combined with agriculture, education, medical care, finance, transportation, tourism, culture, home, life service, media, advertising, retail and other industries to form a new ecological landscape.
2. Accelerate the pace of becoming a network power and actively participate in global Internet governance.
In October, the "Thirteenth Five-Year Plan" proposal adopted by the Fifth Plenary Session of the 18th CPC Central Committee clearly stated: "Implement the strategy of strengthening the country by network and accelerate the construction of a new generation of information infrastructure with high speed, mobility, security and ubiquity". China has nearly 700 million netizens, more than 4 million websites, 1.3 billion mobile phone users, 600 million WeChat and Weibo users, and the market value of 7.85 trillion Internet listed companies. It is a veritable Internet power. At present, four listed companies, Alibaba, Tencent, Baidu and JD.COM, have entered the top 10 global Internet companies. Non-listed companies such as Huawei, Ant Financial and Xiaomi have also entered the top 20 in the world. China’s Internet industry is developing steadily, the market competition is full, and its independent innovation ability is enhanced, and it is making great strides to become a network power.
In 2015, China actively participated in the global Internet development and governance, fully expressed China’s proposition of establishing a new global cyberspace order, and put forward the "China Plan" for Internet development and governance. In September, the Chairman of the Supreme Leader visited the United States, and the two sides reached important consensus on cybersecurity and other aspects, and reached six achievements in the Internet field. In December, China hosted the second world internet conference with higher specifications and larger scale. In the keynote speech of the conference, the supreme leader put forward four principles of respecting network sovereignty, maintaining peace and security, promoting open cooperation, and building a well-ordered global Internet governance system, and five propositions of jointly building a community of cyberspace destiny, which have far-reaching influence.
3. Comprehensively promote the national big data strategy and build a data power.
The 13th Five-Year Plan proposes that China will implement the strategy of strengthening the country through network, the "internet plus" action plan and the national big data strategy. In September, the State Council officially issued the "Action Program for Promoting Big Data Development", which put forward the top-level design of China’s big data development from the overall height of the national big data development strategy. The Ministry of Industry and Information Technology is formulating the "Thirteenth Five-Year Development Plan for Big Data Industry". On November 17, People’s Daily published an article signed by Meng Jianzhu, Minister of Public Security, proposing to co-ordinate the construction of infrastructure such as big data, cloud computing center and Internet of Things.
The convergence of the Internet and human economic and social activities has triggered explosive growth of data. Big data has become the core theme of deepening the development of national informatization and the next starting point for the country to promote the development of informatization. Developing big data has become an inevitable choice for building a data power and promoting big data to govern the country. Local governments have begun to actively seize the opportunity to promote the development of big data. On April 14th, Guiyang Big Data Exchange, the first big data exchange in China, was officially put into operation and completed the first batch of big data transactions. The Southern Data Center of the three major communication operators and the first national comprehensive experimental zone for big data were also completed in Guizhou. On December 12th, Zhongguancun in Beijing released the roadmap and enterprise distribution map of "Big Data" industry to the society for the first time. By 2020, Zhongguancun will gather 600 big data innovative enterprises and cultivate 6,000 enterprises with big data application capabilities.
(B) the level of industry development
1. "internet plus" is more manifested as "moving internet plus".
No matter from the market, equipment, traffic, or from the user’s point of view, the mobile Internet will continue to maintain rapid growth. According to CNNIC statistics, as of June 2015, the number of Internet users in China reached 668 million, while the number of mobile phone users reached 594 million. The proportion of Internet users using mobile phones increased from 85.8% in December 2014 to 88.9%. According to the statistics of iResearch, in the third quarter of 2015, the scale of China’s network economy reached 278.39 billion yuan, with a mobile contribution rate of 36.0%, which is still increasing. In October, the monthly average mobile Internet access traffic reached 361.6M, up 88.3% year-on-year, and the mobile Internet access traffic reached 2.88 billion g, which doubled in October. China has built the world’s largest fourth-generation mobile communication (4G) network.
"internet plus" is more manifested as "Mobile internet plus", and its new products, new applications and new models emerge one after another, laying a solid foundation and creating a broad space for "internet plus" action. In the field of the combination of the Internet and traditional industries, the mobile Internet has seized the limelight, and the investment and financing in the fields of transportation, finance, education, medical care, socialization, tourism, entertainment, life service, e-commerce, advertising and marketing are extremely active. A new round of hardware innovation represented by wearable devices, smart cars and smart homes has flourished, with core chips, operating systems, HTML5, 4G/5G, cloud computing and smart homes.
2. Internet services are vertical and refined, and O2O is reshuffled and adjusted.
Various service fields of the Internet are developing vertically, splitting out more subdivided demands, attracting capital investment and giving birth to entrepreneurial opportunities. Among them, O2O field is the most active, covering almost all peripheral services such as automobiles, tourism, education, take-away, laundry, car washing and housekeeping. With the increase of market competitors, the vertical market is characterized by severe verticalization and refinement, and the adjustment of O2O industry is also in full swing.
Driven by capital and market, the core areas of Internet vertical services, such as online reading, O2O, online travel, and dating networks, began to be strong and strong, and the stronger they became. In January, Shanda Literature and Tencent Literature merged; Didi, quick merger in February; In April, 58 Tongcheng and Jiji.com announced the merger; In October, the public comment, the US Mission announced the merger, Ctrip and Qunar announced the merger; In December, jiayuan and Lily.com announced the merger. There are fewer opportunities left for small and medium-sized entrepreneurs in the whole vertical field, but small and beautiful enterprises are still likely to counterattack by deeply cultivating "the refinement of serving people" and "the uniqueness of consumption scenes".
3. The Internet helps the sharing economy to reconstruct a new format and become a new driving force for future industrial development.
On October 29th, the word "sharing economy" appeared in the communiqué of the Fifth Plenary Session of the 18th CPC Central Committee, and it was proposed to "develop the sharing economy". At the second world internet conference, the Chairman of the Supreme Leader talked about the need to focus on developing new formats such as sharing economy during the 13th Five-Year Plan period. It is the development of Internet technology that makes the sharing economy enter a new stage of development. It is suggested that 2015 is the first year of sharing economy in China.
Sharing economy is a sharp weapon to transform and upgrade traditional industries with Internet thinking. The traditional "rules of the game" in the fields of house leasing, transportation, housekeeping, hotels, restaurants and so on are being changed. Apps such as Didi Chuche, Ride, Dada, Everyone Express, and Going Home for Dinner are typical business products of the sharing economy. The sharing economy is changing the industrial chain structure of the format and reconstructing the original format. This format connects many idle, scattered and silent resources in society, and optimizes the allocation of social resources with the help of mobile Internet, big data and geographical location services, which not only reduces the cost, but also solves the "pain point", to some extent, changes the mode of relying on continuous investment to expand reproduction, and finally breaks the original business rules. The new format and mode of sharing economy are becoming a new driving force to promote the future industrial development.
4. The new network culture is booming, creating a new path for the prosperity and development of the cultural industry.
On October 19th, the Central Committee of the Communist Party of China’s Opinions on Prospering and Developing Socialist Literature and Art put forward that we should vigorously develop online literature and art. Driven by the policy and cultural consumption demand, the emerging network culture is booming. At present, the scale of China’s network culture industry reaches 150 billion yuan, up 200% year-on-year; Online original literary works exceed the sum of works published by paper media in contemporary literature for 50 years. With the rapid and extensive coverage of social media, a number of self-media with the responsibility of spreading knowledge of Chinese studies and promoting traditional culture have sprung up. With the help of the Internet, the overseas spread of China culture has reached an unprecedented breadth.
Internet "IP" (the abbreviation of intellectual property, meaning intellectual property) became the top hot word in the Internet field in 2015. The popular IP derived from online literature became the focus of crazy competition among major film and television companies, and many TV dramas adapted from the Internet "IP" were broadcasted, which triggered many rounds of social debates and highlighted the value of online IP. At present, around the popular "IP", a mature one-stop industry such as film and television drama, online drama, radio drama, comics and game production has been formed. From copyright trading to the production and distribution of film and television content, to the development of a series of derivative products such as games, e-commerce, real entertainment, toys, artists’ brokers, fan economy, etc., the improvement of production and creative ability brings about the feasibility of realizing products in various forms. Network culture has become an important force to promote the rapid development of China’s cultural industry.
5. The independent innovation capability of Internet technology has been enhanced to promote the development of smart industry in China.
In 2015, the development of Internet technology in China achieved major breakthroughs in many fields, such as 4G/5G network technology, mobile chips, intelligent terminals, cloud computing, big data, satellite navigation, etc., showing the characteristics of significantly enhancing the independent innovation capability of network technology, accelerating the catching-up of intelligent terminal manufacturing industry, and constantly cultivating new technologies and applications to form new formats.
At the second world internet conference "Light of the Internet" Expo, the virtual fitting mirrors of Baidu unmanned vehicle, Alibaba Cloud technology, JD.COM "Weilian Smart Home" and Suning "Augmented Reality" displayed the latest technologies, products and applications of the Internet in China. Emerging technologies such as the Internet of Things, virtual reality, smart wearables, drones, service robots, and intelligent networked cars accelerate commercialization. The close combination of Internet and intelligent manufacturing has become the leading mode for the development of Industry 4.0 and smart industry. Traditional manufacturing fields are focusing on creating intelligent factories and interconnected factories, developing intelligent manufacturing equipment, developing intelligent terminal products, encouraging artificial intelligence hardware innovation, and promoting digital and intelligent upgrading of consumer electronics products.
6. Internet and industry are deeply integrated to promote the evolution of new media and communication methods.
In 2015, the pace of traditional media in building new media and promoting media integration was greatly accelerated. A "central kitchen" and a "super editorial department" were set up to carry out process reengineering and institutional reorganization, build a media-integrated cloud platform, open up PCs and mobile terminals, and distribute information around users on demand. Drone news, data news and robot news began to appear. Traditional media in many places launched a new version of the news client, and the People’s Daily client was launched in the third phase. Boundless, Southern Plus, Nine Schools, Cover, Meeting Point, Looking at Chutian and Frontier appeared one after another, and the mobile internet field became the main battlefield for media integration and development. In the future, the development of new technologies such as 4G and 5G mobile communication technology, big data, Internet of Things and wearable smart devices will have a far-reaching impact on the transformation of the media industry. Different channels and forms of media information will be integrated into the digital platform. Internet has eliminated the boundary between media and non-media platforms, and new media groups and modern communication systems with three-dimensional diversity and integrated development are taking shape and developing.
(C) the level of social management
1. The construction of the rule of law in cyberspace has been comprehensively promoted, providing a solid guarantee for the network power.
Cyberspace, like the real society, should not only advocate freedom, but also maintain order. Cyberspace is not an "extra-legal place", which has become a social consensus. Promulgating network security laws and regulations and a series of guiding opinions on industry development, strengthening the governance of cyberspace and cracking down on illegal crimes are the proper meaning of cyberspace governance and the necessary guarantee for building a network power.
Since the 18th National Congress of the Communist Party of China, China’s cyberspace legal system has taken shape, covering many aspects, such as cybersecurity legislation, Internet infrastructure and basic resources legislation, Internet service legislation, e-government legislation, e-commerce legislation and Internet criminal legislation. In July 2015, the "Cyber Security Law" (draft) was open to the public for comments. The Ninth Amendment to the Criminal Law of People’s Republic of China (PRC), which was implemented in November, strengthened the protection of citizens’ personal information and added provisions on the crime of fabricating and disseminating false information. The Telecommunications Law and the Electronic Commerce Law are being drafted. In addition, the promulgation of normative documents and opinions such as Several Opinions on Strengthening the Service and Supervision of Market Subjects by Using Big Data, Action Plan for Promoting the Development of Big Data and Opinions on Strengthening the Supervision of Online Markets has become a supplement to cyberspace regulations.
2. Internet thinking promotes the transformation of government functions and innovates social management.
The development of the Internet should benefit people’s lives and be implemented by the transformation of government functions. In May, the State Council issued the Work Plan for Promoting the Combination of Decentralization, Administration and Transformation of Government Functions in 2015, pointing out that in promoting the innovation of supervision methods and optimizing government services, we should actively use information technology such as big data, cloud computing and Internet of Things to explore a new model of "internet plus supervision". In July, the State Council issued the Guiding Opinions on Actively Promoting the "internet plus" Action, clearly requiring "to build an integrated online public service system for the public and a new model of networked social management service with public participation". The Internet is deeply integrated with the government public service system, which simplifies the public service process with Internet thinking, promotes the equalization of resources, and greatly improves the service level and efficiency of the government. Government websites, Weibo, WeChat and government clients are becoming platforms for providing more convenient, better, all-round and all-weather public services.
At the same time, communications, news, radio and television, finance, retail, transportation and other industries have ushered in great changes in the Internet age. In particular, the transformation of traditional industries inspired by the integration of Internet thinking and sharing economy has brought great challenges to government management. On November 23rd, the State Council issued the Guiding Opinions on Giving Full Play to the Leading Role of New Consumption and Accelerating the Cultivation of New Supply and New Motive Force, proposing to adjust and improve the supporting system conducive to the growth of sharing economic model. Making full use of various channels such as trade associations, enterprises and social organizations to build a new governance model with extensive social participation has become a new idea for innovative social management.
Prospect of Internet Development in China in 2016
It should be noted that the development of things is always one after another and affects each other. In 2016, the influence of established Internet-related development plans, policies and regulations will gradually emerge, and new technologies, formats and models of the Internet will continue to develop. The signs and trends that have already appeared in the Internet market will become clearer. In 2016, China’s Internet development may have the following trends that deserve attention:
1. The Internet extends to the "last mile" and is increasingly becoming the infrastructure for economic and social development.
At present, there are nearly 700 million netizens in China, and the number of fixed broadband access ports reaches 407 million, covering all cities, towns and 93.5% administrative villages in China. With the implementation of the "Broadband China" strategy, it is expected to open up the "last mile" of network infrastructure, reduce the gap of Internet development level between the east and the west and between urban and rural areas, further improve the performance of China’s Internet, reduce network charges, make the achievements of Internet development benefit 1.3 billion people in China, and make the Internet truly become the infrastructure of China’s economic and social development, just like air, land, water and electricity. The information transmission, material exchange, management and even people’s way of thinking in society generally rely on the Internet, and the information society is getting closer and closer to us.
2. "internet plus" connects 360 lines, and the intelligent upgrade is accelerated.
Internet technology represented by big data and the Internet of Things is rapidly permeating the whole industry, and the era of wisdom is quietly coming. The development of Internet will promote the intelligent level of products, equipment, production, management and services in manufacturing industry, and further realize product personalization, customization and batch production, process virtualization, factory intelligence and logistics intelligence. The combination of Internet and traditional industries, on the basis of vertical and refined development, will further carry out intelligent upgrading and transformation, and may achieve breakthrough expansion in the fields of car networking, smart home, wearable devices and machine automation. The supervision and service of government departments will also be more "timely, accurate, efficient and intelligent".
3. Network culture has become a new hot spot for investment, and industrial development promotes cultural prosperity.
In 2015, innovations in cultural concepts, contents, formats and communication channels were more reflected on the Internet. Unconsciously, a group of self-media whose mission is to spread the knowledge of Chinese studies and promote traditional culture have been frequently concerned, attracting a large number of fans; The box office of Chinese movies exceeded 40 billion yuan for the first time, and there have been many successful cases of marketing and publicity in third-and fourth-tier cities through internet channels. Some people say that "small town youth" determines the increase of Chinese movie box office; The "internet plus Culture+Finance" model is highly praised for its combination of investment and financial management, art collection and cultural communication. More and more foreign public get the image perception of China through social networks … The increasingly rich material will inevitably lead to higher spiritual pursuit, and internet plus culture will surely become a hot spot for investment. Some Internet companies have begun to set foot in media, film and television and other cultural industries.
The consumption of Internet cultural products will become a huge market. It will become a trend to promote the effective integration of cultural industry content and channels through the Internet, promote the combination of cultural creativity with the real economy and financial capital, and realize the extension and appreciation of the value of the whole industrial chain. Taking the network as a platform to promote the sharing of cultural achievements and taking culture as a carrier to promote the construction of a community of destiny in cyberspace will become the consensus of cultural inheritance and cultural innovation in the Internet age.
4. Technological innovation, industrial development and space governance to jointly promote the construction of a network power.
There is still a big gap between China and developed countries in terms of infrastructure, technology, industry, network security and network discourse right. Only by breaking the weakness of core technologies such as PC and mobile phone operating system and realizing the leap from consumer Internet to internet plus industry can we promote the development of network economy and network culture and make due contributions to the prosperity of China’s economy and culture.
At the same time, ensuring network security, promoting orderly development and building an Internet governance system will be the theme of China Internet in the future. The concept of interconnection, sharing and co-governance, which originated in China, will spread more widely around the world. More and more Internet enterprises in China will go to the world and drive the development of the Internet all over the world through their own development. China will play a more active role in the development and governance of the Internet, and the pace of becoming a network power will become more and more solid.
Recently, Esther Yu, a post-90s actress, has attracted much attention due to a series of negative events. First of all, her two works "If You Are the One" and "Pray for the Present" have a poor reputation, and her acting skills and face value have been questioned and ridiculed by the audience. Subsequently, some paparazzi photographed her reversing illegally in the emergency lane of the expressway, which triggered a wide public discussion.
With the fermentation of the incident, not only the mainstream news reported it, but also the Beijing traffic police said through Weibo that two minibuses illegally backed out of the main road after missing the exit in the emergency lane. The police also pointed out that the two cars had other traffic violations and were currently under further investigation.
When Esther Yu first appeared at the airport after the high-speed reversing storm, she wore a white down jacket, sunglasses and a mask, dressed in a low-key manner, and clasped her hands all the time, which was in sharp contrast with her usual bright and lively image. Esther Yu’s fans expressed their love for her hand-clasping, believing that it was a sign of her grievance, sadness and helplessness. The last time she clasped her hands, she faced a full screen of abuse on her birthday. Only in this way can she ease her embarrassment. This time, just because she took the bus, she was accused because of the driver’s driving problems. Fans thought she was very pitiful.
However, the majority of netizens didn’t buy the behavior of Esther Yu and his fans. Some people left a message saying that a group of maids were actually distressed by Lao Lai’s daughter, and 208, who didn’t pay back the money at the age of 30, really made people feel distressed. Someone felt distressed when they clasped their hands, so it was better to feel distressed by themselves who had no money first.
For the high-speed reversing incident, Esther Yu Studio issued an apology shortly after the incident, and said that Esther Yu was riding a third-party vehicle, and hoped that everyone would not follow the car and follow. This seems to imply that the driver had to reverse illegally because of stalking fan’s tail. However, it is worth noting that before her debut, Esther Yu had an illegitimate behavior of idolize, including being an actor Kim Soo Hyun’s illegitimate powder, buying the same flight with Lee MinHo, and exposing Lee MinHo’s hotel room number on social platforms. Although these behaviors happened before her debut, as an adult, it is really not advisable for her to go her own way after repeated reminders from the staff.
Nowadays, the Internet has a memory, and Esther Yu’s illegitimate behavior has finally returned to him. Many people don’t understand why capitalists always send their children into the entertainment circle. Esther Yu’s face value and acting skills are average, but she is hard-blown to be cute. Her lines are also embarrassing. It is really puzzling that 40 billion Shanghai princesses should look up to the salary of 208W in the entertainment circle.
Pulmonary nodule has become a high-frequency word on the physical examination list. People pay attention to pulmonary nodules, even to the point of panic, all because part of the nodules is early lung cancer. Especially when the word "ground glass" appears in the inspection report, the patient is more anxious and thinks that the difference is cancer.
Chen Liang, director of the Department of Thoracic Surgery of jiangsu province hospital (the First Affiliated Hospital of Nanjing Medical University), told the reporter that with the increase of cases, the medical consensus on pulmonary nodules is constantly being updated. Now the ground-glass nodules have been classified into the "relative safety zone". As long as the word "ground glass" appears, the nodules are inert, so patients need not be afraid, just follow up regularly. In this big coffee health class, let’s learn more about pulmonary nodules!
With the word "ground glass", nodules are inert.
"Many lung cancers are developed from ground glass nodules!" "Be careful when there are solid components in ground glass nodules, and the malignant probability of semi-ground and semi-solid nodules is the highest!" — — This is the main point that will be mentioned in many popular science of pulmonary nodules before. If there is a "ground glass nodule" on the physical examination list, the fear of patients with pulmonary nodules will escalate. Director Chen Liang told Yangzi Evening News/Zi Niu News reporter that this concept needs to be updated. There are ground glass nodules, but it is relatively safe.
Director Chen Liang explained that infectious diseases such as tuberculosis and fungal infection and chronic inflammation may produce nodules on the lungs. Ground-glass nodules are flaky blurred shadows that we can see on chest CT, just like ground glass. Ground glass nodules are divided into "pure grinding" and "mixed grinding". The diameter of pure ground glass nodules within two centimeters in the international guidelines can be followed up; There are ground glass components and some solid components in the "mixed grinding". The guidelines for this kind of nodules also stipulate that: if the diameter is less than 6 mm, there is no need for follow-up or annual follow-up; 6-8 mm, it is recommended to follow up once every 6-12 months; Those larger than 8 mm are followed up every 3-6 months.
The observation and summary of pulmonary nodules in medicine are also updated. The consensus now is that even if it is already an invasive adenocarcinoma, as long as there is ground glass, it is a low-grade malignant and inert tumor, and the surgical prognosis is excellent.
Don’t intervene too early, even minimally invasive surgery is invasive.
Director Chen Liang said that such patients are often encountered in outpatient clinics. This hospital found nodules by filming and quickly went to a large hospital for enhanced CT or even PET-CT；. Some patients will give an example, "Some people around me have nodules smaller than me, and they are all malignant", so they strongly demand surgery. There will also be patients with three or four millimeters of nodule reports coming from other places to "seek an answer".
Patients often want big experts to determine whether their nodules are cancer. "But the eyes of experts are not microscopes, and sometimes they can’t completely determine whether they are benign or malignant." Director Chen Liang said, is it possible that two or three millimeters of nodules are malignant or have malignant "potential"? It’s a small chance, but it’s possible, but is it wrong for the doctor not to operate? Not really. When a doctor watches a film, what he really needs to grasp is the opportunity of intervention, so as to make the patient benefit the most.
Small nodules of 3-4 mm, some hospitals and doctors may also advise patients to operate, which is actually overtreatment. Minimally invasive surgery is also invasive, and there will be injuries. It is definitely not the optimal solution to let patients who could have been "calm" for several years, more than ten years, or even without intervention for life, bear surgical injuries and various risks prematurely.
Director Chen Liang, for example, said that the patients with pulmonary nodules who were followed up in his hand were suspected to be carcinoma in situ. After 12 years of observation, it was confirmed that they were still carcinoma in situ after surgery. "Atypical hyperplasia, cancer in situ, now think they are precancerous lesions, not cancer. From carcinoma in situ to minimally invasive carcinoma, it seems to be ‘ Advanced ’ In fact, they are only 1-2 mm apart, and the progress is very slow. Many patients are followed up for 5-10 years, and grasping the indications and timely surgery will not affect their health. " Director Chen Liang said that they spend the most time in outpatient clinics, but instead advise patients not to worry, and they can afford to wait.
Big coffee biography
Chen Liang, director of thoracic surgery department of the First Affiliated Hospital of Nanjing Medical University, chairman of the thoracic surgery branch of Jiangsu Medical Association, and president-designate of the thoracic surgeon branch of Jiangsu Medical Association. Committed to the surgical treatment of early lung cancer, he is good at the diagnosis and treatment of thoracic surgery-related diseases, especially lung segments. He has completed more than 1,500 cases of thoracoscopic anatomical pneumonectomy, including more than 500 cases of segmental pneumonectomy and subsegmental pneumonectomy. Thoracoscopic subsegmental pneumonectomy was reported for the first time in the world, which was widely recognized by people in the industry. He has performed surgical demonstrations at conferences at home and abroad for many times, and his technology has spread throughout the country and even abroad. Successfully performed the world’s first mixed reality (MR) assisted lung tumor resection; In China, the concept of "accurate pneumonectomy under the guidance of 3D-CTBA" was first put forward, and the first 3D-CTBA reconstruction system, DeepInsight, was developed in cooperation with Neusoft Company, and the software was successfully copyrighted, which has been widely used in China, including Taiwan Province. He has made many special reports and surgical demonstrations at international and domestic thoracic surgery conferences, and is committed to promoting accurate thoracoscopic pneumonectomy.
He presided over the compilation of the first Atlas of Thoracoscopic Anatomical Segmental Pulmonary Resection in China and the first Atlas of Endoscopic Anatomical Segmental Pulmonary Resection in the world.
The image is hanging in the air, and it can be seen synchronously 30 kilometers away from here.
What kind of nodule needs surgery? Director Chen Liang said that there are "standards" in domestic and foreign guidelines at present. Generally speaking, surgery will only be considered if it is greater than 8 mm. If the nodule is suspected to be carcinoma in situ, micro-invasive carcinoma, or the size, shape and density of the nodule change, follow-up or elective surgery can be selected. If the nodule is located at the periphery of the lung, it is easier to handle, and local resection can be used, with little damage to the lung; If the position is deep, the pulmonary vessels and bronchi may be damaged during the "forced" resection, resulting in postoperative hemoptysis, limited lung expansion and other complications. "At present, minimally invasive surgery has been able to achieve anatomical lung resection, that is, to dissect a lung segment from the lung lobe, while ensuring the margin and minimizing the damage." Jiangsu province hospital is one of the earliest hospitals in China to carry out pneumonectomy, and has trained many domestic thoracic surgeons. The "Anatomical pneumonectomy course" of thoracic surgery has just passed the final certification of the Royal College of Surgeons, and it is also the first training course of pneumonectomy in the world.
In 2017, jiangsu province hospital Thoracic Surgery completed the world’s first thoracoscopic segmental resection of early lung cancer assisted by mixed reality (MR) technology. In 2019, with the help of 5G technology, the first international 5G+MR remote real-time combined segmental pneumonectomy was completed. Under MR technology, after the doctor wears special glasses, the lung image data is "dragged" from the computer screen through artificial intelligence three-dimensional reconstruction, suspended in the air and shared in real time. Director Chen Liang, who is in the hospital headquarters, can mark the image remotely with voice and marker pen, and every instruction detail will appear clearly and without delay in the operating field of the surgeon in the operating room of Pukou Branch, 30 kilometers away. With the support of new technology, the treatment of pulmonary nodules can be more and more minimally invasive and accurate, and difficult remote surgery has also become possible.
See the real pulmonary nodules from the numbers.
Director Chen Liang said that jiangsu province hospital Thoracic Surgery conducted a cohort study of lung cancer in the physical examination center of the hospital. From May 2019 to 2020 (except January-March of the COVID-19 epidemic), a total of 10,225 cases were examined by CT, of which the nodule detection rate was 74.1%, and lung cancer confirmed by pathology accounted for three thousandths of the total number of people examined. It can be seen from this data that the proportion of cancer in pulmonary nodules is still not high.
At the same time, the number of pulmonary nodule operations in jiangsu province hospital was 1,836 in 2016 and 4,393 in 2020, an increase of 139% in five years. At present, the malignant rate of surgical patients is more than 90%.
The increase of pulmonary nodule cases is mainly related to the increase of incidence, the increase of detection rate after the improvement of imaging examination accuracy and the early diagnosis.
What new car can I buy for 70,000-90,000 yuan? In the era of fuel vehicles, we blurted out "Honda, Volkswagen and Toyota to dazzle" three musketeers. In the era of new energy vehicles, BYD directly penetrated the industry threshold at a price of 73,800-89,800 yuan. In the field of small hatchback, BYD Seagull can be regarded as a pure electric flat replacement model of Honda Fit. Although BYD Seagull is positioned as a large-sized micro electric vehicle (close to the size wheelbase of a small car), its interior space performance is close to that of Honda Fit and Volkswagen Polo due to its unique body structure and power layout based on BYD e platform 3.0.
Today, the team leader commented on the 2023 BYD Seagull Free Edition, which is a mid-range model of Seagull. There is no discount at the terminal, and the guide price is 78,800 yuan.
Model: BYD Seagull Free Edition.
Guide price (i.e. bare car price): 78,800 yuan.
The length of the vehicle is 3780mm/ the wheelbase is 2500mm/ the single motor is 75hp /CLTC has a battery life of 305km.
[Satisfied]
The appearance is relatively neutral, and the body structure presents a quite good sense of movement. Because the weight of the vehicle is small and it is an electric vehicle, its dynamic response is fast, the shift is completely without setbacks, the acceleration is very linear, the start is very silky, and there is no noise from the engine, so its quietness has a natural advantage. In addition, the interior materials of this car are also excellent, equipped with leather steering wheel and leather sports style seats, as well as 7-inch full LCD instrument and 10.1-inch central control panel. In this price level, this free version of Seagull is richer and safer than the joint venture car. Seagull comes standard with 4 airbags and front and rear penetrating side air curtains, ESP electronic vehicle stability system, EPB electronic parking, reversing image, cruise control, and the free version is equipped with 16-inch aluminum alloy wheels, ultrasonic radar, satellite navigation, keyless start/entry, external discharge and other equipment functions.
[dissatisfied]
Seagull’s chassis has a general texture and a certain degree of comfort, which is suitable for driving on urban roads. It runs on unpaved roads, and small bumps are not well filtered out. The trunk space is a little small, which is equivalent to sacrificing the trunk for the back row space, and the trunk is not high enough to put much things. Finally, the interior of the new car stage smells very bad, because there are many plastic materials, and there will be a choking smell after exposure.
[Power consumption]
At present, the power consumption per 100 kilometers of this car is 13kWh, because it needs to turn on air conditioning and refrigeration in summer, and the battery life is discounted, basically around 200 kilometers.
[Driving experience]
Seagull is a particularly easy-to-operate vehicle. One is that it is small in size and it is not difficult to drive. Then it has a fast starting speed, light and easy steering and sensitive braking, which is quite suitable for novice drivers and girls. However, it should be noted that after the car starts running, it is necessary to control the turning range, and the roll angle of the car is limited.
[Summary]
BYD Seagull can well replace Honda Fit and Volkswagen Polo, after all, the price is less than 80,000 yuan. It has smooth acceleration performance and quiet driving/riding environment, and it is relatively easy to drive. It only relies on electric power to drive, which is equivalent to saving fuel and money. The cost of using a car is very low, and it costs several yuan for driving 100 kilometers. Generally speaking, this car is very suitable for buying vegetables and taking children to and from school.
Recently, nine China projects were successfully selected as "50 tunnel projects with global influence in the past 50 years", which attracted attention.
A series of tunnels that drill mountains, cross rivers and cross seas have helped to form a railway network of 159,000 kilometers, a high-speed rail network of 45,000 kilometers, a highway network of 5.441 million kilometers and a high-speed network of 184,000 kilometers, connecting the flowing China, witnessing economic development and demonstrating scientific and technological strength.
The world’s longest highway spiral tunnel, the world’s highest high-speed rail tunnel, and the world’s largest single-pipe double-layer tunnel … Today, China has built more than 50,000 kilometers of railway tunnels and highway tunnels, opening up the "throat" and forming the world’s largest high-speed railway network and expressway network.
Recently, at the 2024 World Tunnel Congress held in Shenzhen, the International Tunnels and Underground Space Association (hereinafter referred to as "ITA") released "50 tunnel projects with global influence in the past 50 years", and 9 China projects were successfully selected, with the largest number and the highest proportion.
Many tunnel projects broke the world record.
From old to new, witness the technological changes of China tunnel.
Chengdu-kunming railway Chamarat Da Tunnel, Beijing-Guangzhou Railway Heng-Guang Double Track Dayaoshan Tunnel, Xikang Railway Qinling Tunnel, Qinghai-Tibet Railway Xinguanjiao Tunnel, Hong Kong-Zhuhai-Macao Bridge Immersed Tunnel, Shenzhen Metro Line 14, Shenzhen-China Channel Cross-Harbour Tunnel, Qingdao Jiaozhou Bay Second Cross-Harbour Highway Tunnel … The selected China Project has witnessed the development and changes of China tunnel technology in recent decades.
Chamarat Da Tunnel, a controlled project in chengdu-kunming railway, is located at an altitude of more than 2,200 meters, which has been recognized as a "forbidden zone" by foreign geologists, and underground rivers, faults and mudslides can be seen everywhere.
In March, 1959, the Chamarat Dada Tunnel was started, and it was blasted with a sledgehammer and steel drill, often only half a meter a day. It was under such difficult conditions that the Chamarat Da Tunnel was successfully completed in November 1966, which helped chengdu-kunming railway to open to traffic successfully.
"In order to sacrifice more ambitions and dare to teach the sun and the moon to change into a new sky," Chamarat Da Tunnel laid the spirit that China tunnel people are not afraid of hardship, fatigue and being the first. " Yan Jinxiu, former chairman of the International Tunneling Association and chief expert of China Railway Research Institute, said.
Dayaoshan Tunnel, the key tunnel of Beijing-Guangzhou Railway Hengguang Double Track, with a total length of 14.295 kilometers, is the first super-long double-track electrified railway tunnel in China.
"Dayaoshan Tunnel has to cross dozens of large and small faults. The rock stratum is broken, the stability is extremely poor, and the water permeability is extremely strong. The disturbance caused by tunnel construction to the mountain is very easy to cause collapse and mud gushing." The relevant person in charge of the China Railway Tunnel Bureau recalled that if you want to build the Dayaoshan Tunnel, the old method will not work and you must ponder and innovate.
To this end, China Railway Tunnel Bureau actively carried out technological innovation, introduced advanced technology and equipment, and adopted the brand-new construction technology "New Austrian Tunneling Method" to build Dayaoshan Tunnel, creating 11 records. In 1992, Dayaoshan Tunnel won the national special prize for scientific and technological progress, leading China’s tunnel construction to achieve a breakthrough in the whole system.
Since then, China tunnel technology has grown rapidly.
Qinling Tunnel, a controlled project of Xikang Railway, is the first railway tunnel constructed by full-face tunneling machine (TBM) in China, which indicates that tunnel construction in China has entered the stage of shield /TBM factory construction.
Xinguanjiao Tunnel, the control project of the second line of Xi (Ning) Ge (Ermu) of Qinghai-Tibet Railway, is the first time in the history of tunnel construction to build a tunnel with a length of more than 30 kilometers at an altitude of more than 3000 meters and under the complex geological environment of Qinghai-Tibet Plateau.
The immersed tube tunnel of Hong Kong-Zhuhai-Macao Bridge is the longest highway immersed tube tunnel and the only deep-buried immersed tube tunnel in the world, and it is also the first immersed tube tunnel in the open sea in China. The submarine part of the tunnel is about 5664 meters, which consists of 33 giant immersed tubes and a final joint of a closure section. The maximum installation depth is over 40 meters, and it is called Mount Everest in traffic engineering.
The deep middle passage subsea tunnel is about 6.8 kilometers long, of which the immersed tube tunnel is about 5 kilometers long, which is the longest and widest immersed tube tunnel with steel shell and concrete in the world.
"In 1990, when China held the World Tunnel Conference for the first time, it received help from all countries in the world." Yan Jinxiu proudly said that 34 years later, after a lot of engineering practice, we have accumulated a number of innovative achievements and experiences, which can be shared with our peers in the world.
The scale of tunnel construction has increased rapidly.
Form the world’s largest high-speed railway network and expressway network.
From 1990 to now, in the past 34 years, the scale of tunnel construction in China has increased by 24 times, and the construction mileage has exceeded half of the world total.
Today, more than 50,000 kilometers of railway tunnels and highway tunnels have been built in China, opening up the "throat artery" and forming the world’s largest high-speed railway network and expressway network.
Data show that by the end of 2023, there were 18,573 railway tunnels in operation, with a total length of 23,508 kilometers. Among them, there are 4,561 high-speed railway tunnels with a total length of 7,735 kilometers. By the end of 2022, there were 24,850 highway tunnels in operation, with a total length of 26,784,300 linear meters.
The road network is extended and the train is speeding. In the first quarter of this year, the national railways sent 1.014 billion passengers, with an average of 11.147 million passengers per day, a year-on-year increase of 28.5%. During the "May 1" holiday, there were 1.358 billion people moving across regions in the whole society, showing the surging momentum of China’s economy.
In today’s China, 8,543 kilometers of subway have been built, which has significantly improved the operation efficiency of the city and greatly facilitated people’s travel.
Take Shenzhen as an example, the land area is less than 2,000 square kilometers, and the actual management service population exceeds 21 million. By continuously expanding the development space underground, people’s lives are facilitated.
By the end of 2023, the operating mileage of Shenzhen urban rail transit network (including trams) has increased to 567.1 km, and the number of stations has increased to 393 (including interchange stations, excluding Fulin stations). The density of urban rail transit network (calculated by administrative area) has reached 0.28 km/km2. In 2023, the rail transit (including trams) network in Shenzhen transported about 2.711 billion passengers, and the passenger traffic increased by over 56% year-on-year.
Today, China has built 5,100 kilometers of underground utility tunnel, which has strongly promoted the intensive development of the city and enhanced its resilience.
Xiong’an new area is the first city in China to adopt all-underground utility tunnel. In Rongdong District, the first centralized built-up area in the new district, there are no manhole covers and wires on the street, and all pipelines such as electricity, gas, water supply and signals enter the underground utility tunnel.
Relying on the new generation of information technologies such as big data and Internet of Things, the pipe gallery builds a wireless Internet of Things sensing network, builds a smart operation and maintenance platform, conducts online and offline inspections, and pursues safe, intelligent, accurate and efficient operation. Not only xiong’an new area, but also Beijing, Chongqing, Zhuzhou and other cities have built underground utility tunnel, effectively saving land space and releasing development space.
"China has become the country with the largest number of tunnels, the largest construction scale and the fastest development speed in the world today." Ni Hong, Minister of Housing and Urban-Rural Development, said that the construction of tunnels and underground projects has made the best use of land and the smooth flow of goods, promoted rapid economic and social development, effectively improved people’s livelihood and played an important role in Chinese modernization.
March towards full automation and intelligence
China tunnel construction has entered the stage of complete independent innovation.
"Now, we can proudly say that China’s tunnel construction concept and construction method have reached the world leading level." Yan Jinxiu said, especially the tunnel construction equipment represented by the large shield is all localized, and the extreme technical challenge represented by crossing the river and crossing the ocean and deep-buried tunnels on the plateau, the tunnel construction in China has entered the stage of completely independent innovation, marching towards a higher level of full automation and intelligence.
On the morning of April 29th, with the slow rotation of the cutter head of the "Pilotage" shield machine, it marked that Chongtai Yangtze River Tunnel entered the stage of shield construction in an all-round way, and started the journey of single-headed tunneling across the Yangtze River with super-large diameter shield.
It is reported that the "Pilotage" shield machine has to work 89 meters underwater in the Yangtze River, heading 11.3255 kilometers with its own head, connecting Chongming in Shanghai and Taicang in Jiangsu, and realizing the high-speed rail crossing the river without slowing down for the first time.
Not only Chongtai Yangtze River Tunnel, but also many large-section tunnels under construction in China, such as Suzhou East Tunnel, a new Nantong-Ningbo high-speed railway, which is known as "the first urban high-speed railway tunnel in China"; Jintang subsea tunnel of Ningbo-Zhoushan Railway is the longest subsea high-speed rail tunnel in the world.
It is one of the characteristics of China tunnel construction to challenge the tunnel engineering under more complicated geology. Gaoligongshan Tunnel is one of them.
As a control project for the entire line of the Da-Rui Railway, Gaoligongshan Tunnel is the first extra-long railway tunnel in the world to cross the Hengduan Mountains. The maximum buried depth of the tunnel is 1,155 meters, and there are as many as 18 kinds of strata that the whole tunnel passes through, including 19 fault zones, which can be called the "geological museum" in the history of railway construction, covering almost all the unfavorable geology and major risks of tunnel construction.
As of May 5, the main tunnel of Gaoligongshan Tunnel has completed 17.8 kilometers, leaving 16.7 kilometers; The parallel pilot tunnel completed 18.1 kilometers, leaving 16.4 kilometers.
The China Railway Tunnel Bureau is responsible for the construction of this tunnel. "The China Railway Tunnel Bureau participated in the construction of seven of the eight projects shortlisted in Chinese mainland, and the Gaoligongshan Tunnel is our new milestone." The relevant person in charge of the China Railway Tunnel Bureau said.
A few days ago, more than 30 international tunnel experts attending the World Tunnel Conference specially rushed to the shield tunnel section of Shenzhen Qianhuang Section of Guangzhou-Dongguan-Shenzhen Intercity Railway for a visit. "In just 3.5 kilometers, this tunnel has to pass through 28 major risk points such as high-speed rail and subway lines, and 128 pipelines. It is the shield tunnel project with the highest comprehensive risk and the most difficult construction among similar projects at home and abroad." Liu Ziming, project leader of China Railway 22 nd Bureau Group, said.
"At present, global tunnels and underground projects are still in a period of rapid development, with broad development space." Chen Yun, Party Secretary and Chairman of China Railway Engineering Group Co., Ltd. said that in the future, China tunnel workers will not only build ultra-deep, ultra-long and ultra-complex tunnel projects and underground spaces with larger sections and deeper burial depth, but also devote themselves to practicing the concept of green and low-carbon development, actively develop intelligent construction and intelligent operation and maintenance, and build a world-class tunnel project.
Editor’s Note: The 5th world internet conference opened in Wuzhen, Zhejiang on November 7th, and the Supreme Leader of president sent a congratulatory letter. The Supreme Leader pointed out that today’s world is experiencing a broader and deeper scientific and technological revolution and industrial transformation.
Facing the changes and challenges of the global Internet, what kind of answer will China give? The world is looking forward to it..
In different historical stages of the development of human society, the social production network has been expanding, from one country to many countries, and from many countries to the final globalization. In this process, the social production network has become increasingly complicated in space, between industries and even within products. At the same time, the key content of production network exchange has gradually changed from agricultural products, industrial products and capital flow to data flow and information flow. Economic powers also show different industrial characteristics at different stages: agricultural power, industrial power, trade power and financial power. Under the background of the internet age, information flow and data flow are becoming new means of production, and at the same time, they are becoming more and more important contents of national security, and economic powers will increasingly rely on network powers.
The world today is experiencing an information revolution, which will bring another qualitative leap in productivity and have a profound impact on the development of international politics, economy, culture, society, ecology and military affairs. China must seize this historical opportunity, and use information flow to drive the flow of technology, capital, talents and materials to promote high-quality economic development. China has its own unique advantages in building a network power.
China has the advantage of market scale in building a network power.
The network has the characteristics of increasing marginal revenue. Every time a new user is added to the network, its scale revenue will be greater. China has a population of nearly 1.4 billion, and the existing Internet users and mobile phone users are huge. From children to the elderly, almost everyone can use smart phones. China’s population advantage is a huge supporting force for building a network power, which is an innate condition that many developed countries in the world do not have. There are world-class Internet companies like Ali and Tencent in China, which is inseparable from the huge domestic market in China. Making full use of population advantages and giving full play to the role of population base can make China’s network power construction get twice the result with half the effort and form a huge scale effect on economic development.
Today’s network era is already different from the traditional free Internet era, and innovations in content and form have spawned various profit models. The network era will not bury anyone’s talent, and every participant can use the network to create wealth. They are both creators and users of Internet services. Therefore, building an all-round cyberspace and expanding the coverage of network infrastructure can make China’s market scale advantage play to the greatest extent in the construction of a network power.
Building a strong network requires higher talents and infrastructure.
The characteristics of a network power are as follows: a country has strong technical strength, strong ability to resist network risks and network governance, which can achieve a high level of network efficiency as well as a high level of network security. No matter what stage of social development, talents and infrastructure are two important pillars of building an economic power. The innovation ability of the former depends on the national talent training and incentive system, while the latter depends on the government’s investment, supervision and maintenance of infrastructure. The construction of a network power still needs to rely on the construction of Internet talents and network infrastructure.
For a micro-enterprise, the Internet is first and foremost a technology-intensive industry, which cannot be supported by first-class technical talents. After more than 20 years of unremitting efforts, China has gained gratifying achievements and rich technical experience and professionals in the field of Internet technology. Since 2003, the number of related patents applied by China has increased by 10% year by year. Stimulated by market demand, a large number of college graduates flock to Internet enterprises after graduation, providing a large number of IT talents for the Internet industry. The younger talent team is more conducive to technological progress and innovation. In 2017, among the top ten Internet companies in the world ranked by market value, China’s Alibaba, Tencent, Baidu and JD.COM occupied four of them. China’s Internet practice and innovation is based on its own national conditions, permeating all aspects of people’s daily life, and basic production and life have been closely linked with intelligent networks. However, although the total resources of Internet science and technology talents in China are large, high-end technical talents are still scarce resources.
For a country, especially for a big country like China, the construction of a network power has put forward higher requirements for infrastructure. The infrastructure referred to by a network power includes not only telecommunications and Internet infrastructure construction in a narrow sense, but also the interaction between the network economy and the real economy. Network infrastructure also includes network basic theory and core technology, as well as related facilities related to network security. For example, information infrastructure network security protection, network security information co-ordination mechanism, means and platform. "To get rich, build roads first", and network infrastructure is the "highway" in today’s information age.
The essence of a network power is an information technology power. Network development is supported by technology, and the core technology is the biggest difficulty that restricts China’s construction into a network power. With the core technology, we can have a comparative advantage in technology, from following developed countries to completing "overtaking in corners". The birth of the core technology is to try it out through massive trial and error. This not only requires that the scientific research assessment mechanism should be inclusive and allow researchers to fail; But also put forward higher requirements for the financing mechanism, that is, the financing mechanism should also be inclusive and tolerant of repeated failures in technical research. Therefore, our scientific research assessment mechanism should be reformed, from short-term and high-frequency assessment to longer-term assessment, from quantitative assessment to quality assessment and peer reputation assessment. In addition, for the financing mechanism, it also requires the development of equity financing, the development of multi-level capital markets, and the change of the financing structure mainly relying on bank loans.
China’s construction of a network power is facing the problem of integration with the real economy
Undoubtedly, the development of the Internet has played a positive role in promoting economic development, but at the same time, new technologies will have an impact on traditional industries. This "creative destruction" of the network economy has also caused a certain degree of impact on the real economy. For example, the retail service industry tends to weaken under the impact of the Internet. We need to understand this contradiction from two aspects: on the one hand, like other new technologies and new production methods in history, network technology has improved the efficiency of information flow and production, and it is the "cake" of the whole economic output. The distribution problems arising in this process require the state to maintain basic social equity through taxation, subsidies and redistribution; On the other hand, the real economy and the Internet can achieve a benign interaction and achieve a win-win situation for both sides.
