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

1. Two cloned monkeys were born in China. After five years' efforts, the Sun Qiang team of the Institute of Neuroscience of China Academy of Sciences has cultivated cloned monkeys "Zhongzhong" and "Huahua", which indicates that China has successfully broken through the world problem that the existing technology cannot clone primates, and initiated the era of using macaques as experimental animal models.

2. The joint research team led by Peking University Jiang Ying and Academician Wang Enge of Chinese Academy of Sciences obtained the atomic image of hydrated ions for the first time, and found the "magic number effect" of its transport, which will show broad application prospects in ion batteries, seawater desalination, life sciences and other fields.

3. the domestic large amphibious aircraft AG600 successfully achieved its first flight on the water. AG600 is the largest amphibious aircraft under research in the world at present, which is of milestone significance to fill the gap of emergency rescue aircraft in China and meet the needs of national emergency rescue and natural disaster prevention and control system capacity building.

4. The Hong Kong-Zhuhai-Macao Bridge was completed and opened to traffic. Hong Kong-Zhuhai-Macao Bridge is the longest sea-crossing bridge, the longest steel structure bridge and the longest submarine immersed tunnel in the world. It is also the bridge with the most complicated technology, the most difficult construction and the largest project scale in the history of highway construction, creating a series of "the best in the world".

5. Build the first deep-sea real-time scientific observation network. China's new generation marine comprehensive scientific research ship "Science" returned to China in February 20 18 after completing its comprehensive voyage to the western Pacific Ocean on 20 17, marking the completion of China's first deep-sea real-time scientific observation network. The continuous real-time data obtained provide important basic support for climate prediction and environmental protection in China.

People's Network-The wave of scientific and technological innovation is surging, and major achievements emerge one after another.
