What are the scientific and technological achievements of China in the 2 1 century?

The Hard X-ray Modulation Telescope (HXMT) satellite is the first X-ray space astronomical satellite in China. It can not only survey the sky with wide-band large-field X-rays, but also study the short-time scale light variation and wide-band energy spectrum of high-energy celestial bodies such as black holes and neutron stars. It is also a highly sensitive all-day monitor for gamma ray bursts.

On June 5, 20 17, the HXMT satellite was successfully launched for scientific observation. On October 30th, 2065438+200865438+/KLOC-0, China's first X-ray astronomical satellite "Yan Hui" was officially put into use. Goggles HXMT telescope has a design life of 4 years.

2. Shenwei Taihu Lake Light

Shenwei Taihu Light Supercomputer is a supercomputer developed by National Parallel Computer Engineering Technology Research Center and installed in Wuxi National Supercomputing Center.

20 16 On June 20th, at the World Supercomputing Conference held in Frankfurt, the list released by the international TOP500 organization showed that the supercomputer system Shenwei Taihu Light topped the list, which was not only nearly twice as fast as the second Tianhe II, but also improved its efficiency by three times.

165438+1October18th, Chinese researchers won the "Gordon Bell Award" for the first time based on the application results of the "Shenwei Taihu Light" supercomputer, achieving a zero breakthrough in the application results of high-performance computing in China.

3. The new navy destroyer was launched.

The new navy destroyer is a new 10,000-ton destroyer independently developed by China. It has successively broken through a series of key technologies such as overall design, information integration and final assembly construction of large ships, equipped with new air defense, anti-missile, anti-ship and anti-submarine weapons, and has strong information perception, air defense and anti-missile capabilities and sea attack capabilities. It is a landmark warship for the navy to achieve strategic transformation and development.

The launch of the ship marks a new step in the development of China's destroyers, which is of great significance for improving the naval equipment system structure, building a powerful modern navy and realizing the Chinese dream of strengthening the military. Next, the ship will carry out equipment debugging and mooring navigation test as planned.

4. superconducting tokamak experimental device EAST

The working principle of the fully superconducting tokamak nuclear fusion experimental device is to add a small amount of hydrogen isotope deuterium or tritium into the vacuum chamber of the device, generate plasma by using the principle similar to transformer, and then increase the density and temperature to make it undergo a fusion reaction, which will generate huge energy during the reaction.

In 2009, the first round of physical discharge experiment of the world's first fully superconducting noncircular cross-section tokamak nuclear fusion experimental device (EAST) was successful, which indicated that China stood at the forefront of nuclear fusion research in the world. From February, 2065438 to February, 2006, a major breakthrough was made in the EAST physics experiment in China, and the longest-lasting plasma discharge with an electron temperature of 50 million degrees was realized internationally.

5. ITER program of international thermonuclear fusion experimental reactor

The International Thermonuclear Experimental Reactor (ITER) project is one of the largest and most influential international scientific research cooperation projects in the world. The construction time is about 65,438+00 years, and the cost is 5 billion US dollars (65,438+0,998).

ITER device is a superconducting tokamak that can produce large-scale nuclear fusion reaction, commonly known as "artificial sun". On June 5438+ 10, 2003, the State Council approved China to participate in ITER plan negotiations. In May, 2006, with the approval of the State Council, China's ITER negotiating team initialled the ITER Plan Agreement with the European Union, India, Japan, South Korea, Russia and the United States on behalf of the China government.

China's participation in ITER is based on its long-term basic demand for energy. 20 13 1.5, Hefei Institute of Matter, China Academy of Sciences announced that the neutral beam injection system of the auxiliary heating project of the "artificial sun" experimental device successfully realized the extraction of hydrogen neutral beam with a long pulse of 100 second on the comprehensive test platform.
