1, Tianhe-2 supercomputer

In 2013, China's Tianhe-2 was officially unveiled, in the three years since then, Tianhe-2 in the global supercomputer list to maintain the "six consecutive titles", the first chair. Tianhe tops the list with peak computing speed of 549 million times per second, sustained computing speed of 339 million times per second double-precision floating-point operations with excellent performance. Tianhe-2 has been applied in many fields such as biomedicine, new materials, engineering design and simulation analysis, weather forecasting, smart city, e-commerce, cloud computing and big data, digital media and animation design, etc. It will also be widely used in the fields of large-scale science, large-scale engineering and informatization, and will provide an important support for the transformation and upgrading of the economy and society.

2, "Wukong" detector

China's "Wukong" dark matter detection satellite is tasked with the mission of searching for evidence of the existence of dark matter in space, which is the space detector with the widest range of observational energy bands and the best energy resolution to date, surpassing all similar international space detectors. It is the space detector with the widest observation energy range and the best energy resolution so far, surpassing all similar detectors in the world. The technical indicators of the scientific load have reached the international advanced level.

3. China's High-Speed Railway

The construction of China's high-speed railway started during the 11th Five-Year Plan. By the end of 2015, the mileage of China's high-speed railroad will reach 18,000 kilometers, and the high-speed railroad as the skeleton, including inter-area express railroads, intercity railroads, and speed-up lines of existing lines, etc., will basically complete the express railroad network, with a total scale of 40,000 kilometers or more, basically covering the cities with a population of more than 500,000 people.

4, domestically produced aircraft

Strictly speaking, the international shipping system, accustomed to more than 300 seats of the passenger aircraft known as large passenger aircraft; while in China, people usually more than 150 seats of the passenger aircraft known as large passenger aircraft. China's domestic aircraft C919 off the line reflects the country's progress in science and technology. C is the aircraft manufacturer - China Commercial Aircraft Corporation (COMAC) initials, while representing China (China). The first number 9 in "919" represents the Chinese symbol of "天长地久"; "19" means that the model has a maximum capacity of 190 passengers.

In the wheel of history, we came from the Stone Age to the Iron Bronze Age, then into the steam era, then came to the electrical era, and finally the current information age. Technology, like life, is constantly evolving. For example, the evolution of aircraft, the Wright Brothers manufactured the first aircraft to our current large aircraft, military aircraft; Richard? Trevithick created the world's first train, to the current Chinese high-speed rail.
