At present, China ranks first in the world in shipbuilding. According to the data released by British Clarkson Research Company in February this year, in 2065438+2009, the world shipbuilding was 98.82 million deadweight tons, of which China shipbuilding was 36.72 million deadweight tons, accounting for 37.2%. At present, this figure is ahead of other countries in the world.
In addition, in 2065438+2009, the global hand-held orders for shipbuilding were187.64 million dwt, of which the hand-held orders of China shipbuilding industry were 81660,000 dwt, accounting for 43.5%. In the past 10 years, China has gradually developed into the largest shipbuilding center in the world.
2. Cement production, chemical fiber production, automobile production, mobile phone production, total trade volume, Internet users and furniture exporting countries all rank first in the world.
3. In the fields of bridge construction technology, plateau railway technology and hybrid rice technology, China is also in the forefront of the world and even ranks first.
4.UHV transmission
Both UHV AC drive and UHV DC drive are well-deserved first in the world. In 20 10, two national demonstration projects of 800 kV Yunnan-Guangdong and Xiangjiaba-Shanghai were completed. 160 many units and tens of thousands of researchers Qi Xin worked together to tackle key problems, completed 14 1 key technology research, created 37 world firsts, and established the world's first UHV DC technology system, which stood tall in one fell swoop. At present, this technology has been exported to Brazil, India and other countries.
5. Petroleum seismic exploration field
China petroleum geophysical exploration technology began to develop from 1939. Since 1960s, China has entered the stage of large-scale geophysical prospecting. The 1970s witnessed the great development of petroleum geophysical exploration in China, with more than 350 geophysical exploration teams.
After entering the 2 1 century, China has made great progress in three-dimensional visualization system, borehole monitoring technology, depth domain seismic information display technology, full vector wave field imaging technology, intelligent oilfield development monitoring technology, supercomputer technology and other fields.
Strictly speaking, it is more accurate to define this item as oil land seismic exploration. Because companies such as BP should be better at marine seismic survey than China. By the way, the biggest breakthrough in the field of marine seismic oil exploration in recent years was made by a China scientist named Shen, but it's a pity that he is a researcher of BP.
