What are the world’s first places in our country?

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 Lift off. 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 China Standardization, etc.

3. Supercomputer technology:

"Tianhe-2" is a supercomputer system developed by the National University of Defense Technology. It has a peak computing speed of 5.49 billion times per second and continuous computing. The excellent performance of 339 petaflops of double-precision floating point operations ranks first.

4. Manned submersible technology:

The Jiaolong manned submersible is a manned submersible independently designed and independently developed by China. The Jiaolong manned submersible The vehicle has carried out multiple diving missions in the South China Sea, with the maximum diving depth reaching 7,020 meters.

5. China’s Sky Eye:

The 500-meter aperture spherical radio telescope is known as the “China’s Sky Eye”. 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.
