Under the guidance of the Party's policy of reform and opening up and the policy of rejuvenating the country through science and technology, China is entering an era of continuous and brilliant appearances of major powers.

Among them, high-speed railway is undoubtedly one of the most brilliant stars.

two thousand and three In, the Ministry of Railways put forward the leap forward development route, defined the technical route of overall introduction of technology, digestion and absorption, gradual realization of localization, and striving to reach the international advanced level. Under the overall planning of the Party's policies, enterprises successfully obtained the world's advanced high-speed railway technology through two rounds of large-scale introduction, exercised the design ability, possessed the manufacturing ability, and realized the technology accumulation, It has caught up with the world's advanced level.

two thousand and nineteen Year 12 On October 30, the 350km intelligent Beijing Zhangjiakou high-speed railway was officially opened and operated, which is the first intelligent high-speed railway in China that uses the Beidou satellite navigation system and realizes automatic driving and other functions. Since then, China's high-speed railway has stood at the center of the world stage, representing the most advanced industry technology in the world.

After the high-speed railway, Beidou has become another big power that affects people's livelihood.

two thousand At the end of this year, Beidou-1 system will be built to provide services to China, 2012 The Beidou-2 system, completed by the end of the year, provides services to the Asia Pacific region; At 9:43 on June 23, 2020, the last networking satellite of China's Beidou-3 system was successfully launched, and the constellation deployment of the Beidou Global Navigation System was completed. China has become the third country in the world to have a global satellite navigation system.

As a major international project decided and implemented by the CPC Central Committee, the Beidou system means that China can also use the satellite navigation system independently, not only in military, but also in civilian, such as communication, power grid, finance and other industries that need the precise positioning and time service functions of navigation satellites, to get rid of the previous situation of being constrained by others.

two thousand and nineteen Year 6 In August, China officially issued a 5G commercial license. Based on the technical support of Huawei, ZTE and other enterprises, as well as the obvious advantages of the world's largest user scale, huge 4G network, and rich mobile Internet applications, plus the high attention of the government and the active efforts of enterprises, China's 5G development has become inevitable to lead the world.

If 5G It is the core of communication at present, and quantum technology is an important weight to focus on the long-term future.

two thousand and twenty Year 10 In the afternoon of October 16, the Political Bureau of the CPC Central Committee held the 24th collective learning on the prospects of quantum technology research and application. Xi Jinping, General Secretary of the CPC Central Committee, pointed out that quantum technology has developed rapidly in recent years, becoming the forefront of a new round of scientific and technological revolution and industrial reform. Accelerating the development of quantum technology plays a very important role in promoting high-quality development and safeguarding national security.

two thousand and sixteen In, China launched the world's first quantum science experiment satellite "Mozi", becoming the first country in the world to realize quantum communication between satellites and the ground.

In terms of quantum computing, the team of China University of Science and Technology will In, it took about 200 seconds to solve the wave color sampling problem by using the photon quantum computing system, the nine chapter quantum computer, while it took about 600 million years for Fuyue, the world's first supercomputer, to perform this calculation.

Of course, quantum computing and supercomputers are not the same kind of products. Supercomputers that can be applied to general computing are of great significance for nuclear reaction simulation, astrophysical simulation and even weather forecasting.

In fact, in 1958 In, China began its exploration in the field of supercomputers. From the first digital electronic computer 103 to the successful development of the "Galaxy" series supercomputers in 1983, to the Dawning series and Shenwei supercomputers, China's development in this field is getting faster and faster, with more and more achievements.

A very important application field of supercomputers is aerospace missions. The manned space test platform "Tiangong-1", which is independently developed by China, used the "Shenwei Taihu Light" supercomputer to conduct large-scale parallel simulation of aircraft status, using more than 15000 The supercomputer simulation results are basically consistent with the wind tunnel test data, providing important data support for the "Tiangong-1" flight test.

The dream is beautiful because of struggle. For more than 50 years, thousands of ordinary Chinese hearts have gathered powerful forces to tackle the difficulties and hold up the millennium dream of the Chinese nation.

From Beidou networking, "Jiaolong" entering the sea, "Tianyan" patrolling the air, to Hong Kong Zhuhai Macao Bridge, Beijing Daxing International Airport, and the "Belt and Road" to jointly build a community of shared future for mankind, stories of struggle and great achievements have impressed the world.

As General Secretary Xi once put forward at the National Conference on Science and Technology Innovation, "Science and technology is a powerful tool for the country. The country relies on science and technology to become strong, enterprises rely on it to win, and people rely on it to live a good life. If China wants to become strong and the Chinese people live a good life, it must have strong science and technology." Over the past 100 years, under the leadership of the Communist Party of China, the Chinese people have used science and technology to create a way to save and revitalize the country The road to becoming rich and powerful. Today's China is also rapidly transforming the latest science and technology into productivity with unprecedented innovation courage, innovation ability and innovation speed. On the road of independent innovation with Chinese characteristics, facing the world's scientific and technological frontier, the main battlefield of the economy, and the major needs of the country, we will accelerate scientific and technological innovation in all fields, and grasp the opportunities of global scientific and technological competition.
