(1) On June 65438+February 2, 2000, the second Beidou navigation test satellite developed by China was successfully launched, which together with the first Beidou navigation test satellite launched on June 65438+1October 3, 2000 constituted the Beidou navigation system. This indicates that China will have the first-generation satellite navigation and positioning system independently developed. After the system is completed, it will mainly provide navigation services for highway transportation, railway transportation, offshore operations and other fields, and will play a positive role in China's national economic construction.
(2) 20011China's "Shenzhou II" was launched from Jiuquan Satellite Launch Center in China and successfully entered the scheduled orbit. On June 65438+1October16th, the "Shenzhou II" unmanned spacecraft returned accurately and landed successfully. This is the first launch of China space flight in the new century and the second flight test of China's manned spaceflight project, which marks an important step for China to realize manned flight.
2. Great achievements have been made in the field of nanotechnology.
Scientists in China are at the forefront of international science and technology in nanotechnology research. Recently, scientists in China have directly discovered the "peculiar" property of nano-metals-superplastic ductility for the first time in the world. Nano-copper can be stretched more than 50 times at room temperature, which is known as "a breakthrough in this field, and it shows people for the first time how void-free nano-materials are deformed". Generally speaking, China ranks fourth in the world in the total number of nano-papers, and has occupied a place in the international research of nano-materials.
3. Supercomputer intelligence
On June 29th, 2000, the first humanoid robot independently developed by China, which has human appearance characteristics and can simulate human walking and basic operation functions, made its debut at Changsha University of National Defense Technology. The appearance of humanoid robot indicates that China robot technology has entered the international advanced ranks.
