What achievements does our country have that ranks first in the world?

1. Quantum communication technology

The Micius quantum science experimental satellite was successfully launched from Jiuquan at 1:40 on August 16, 2016 using the Long March 2D carrier rocket. null. The complete success of this launch mission marks another important step in my country's space scientific research. The quantum communication technology led by the Chinese Academy of Sciences has achieved the most advanced status in the world.

2. High-speed rail technology

China has independent high-speed rail technology, which is mainly reflected in the independence of IGBT technology, the localization of high-speed train chips, the construction of high-speed railways by national civil engineering central enterprises, and the high-speed trains in China Standardization etc.

China is already at the forefront of the world in this research. In 2007, this project was listed as a National Natural Science Foundation project. A large number of related patents applied by experts such as Professor Zhang Yaoping have been accepted. A transportation revolution is imminent. The operating speed of the vacuum tube maglev train can theoretically approach the first cosmic speed, reaching 20,000 kilometers.

3. Supercomputer technology

"Tianhe-2" is a supercomputer system developed by the University of Defense Technology, with a peak calculation speed of 5.49 billion times per second and a continuous calculation speed of The outstanding performance of 339 petaflops of double-precision floating point operations ranked first, making it the world's fastest supercomputer in 2013.

4. Manned submersible technology

The Jiaolong manned submersible is a manned submersible independently designed and independently developed by China. It is also one of the 863 projects. Major research projects. From May to July 2010, the Jiaolong manned submersible conducted multiple dive missions in the South China Sea, reaching a maximum diving depth of 7,020 meters.

On March 4 and 7, 2017, the "Jiaolong" manned submersible conducted the 38th China Ocean Voyage in the Wocan No. 1 hydrothermal area and Dalian hydrothermal area in the northwest Indian Ocean respectively. The 3rd dive and the 4th dive of a leg.

Both dives discovered hydrothermal vents and obtained sulfide samples in the survey area. On May 23, the "Jiaolong" completed the deepest dive in the world. The submersible stayed underwater for nearly 9 hours, and the submarine operation time was 3 hours and 11 minutes. The maximum diving depth was 4,811 meters.

5. China’s Sky Eye

The 500-meter aperture spherical radio telescope is known as the “China’s Sky Eye”. It was conceived by Chinese astronomer Nan Rendong in 1994 and took 22 years to build. It was inaugurated on September 25, 2016. It is led by the National Astronomical Observatory of the Chinese Academy of Sciences and is the world's largest single-aperture and most sensitive radio telescope with my country's independent intellectual property rights. The comprehensive performance is ten times that of the famous radio telescope Arecibo.
