1988年,我国要进行中长期气象预报,需要从美国购买一台超级计算机,但美国人提出了很多令人无法接受的条件。1992年,我国成功研制出了运算速度达每秒10亿次的“银河二号”超级计算机,开始用于气象预报。这时,美国人才不情愿地将机器卖给我们,可是他们却制造了一个令人刺痛的场景。据当时的技术人员杨学军回忆,当时放这台超级计算机的屋子由美国人24小时监控维护,不允许中国人进去。时至20年后的2007年,在国际计算机年会上,已经成为国防科技
In 1988, China needed long-term and medium-term weather forecasts, and it needed to buy a supercomputer from the United States. However, Americans made many unacceptable conditions. In 1992, China successfully developed the “Galaxy II” supercomputer with a computing speed of 1 billion times per second, and began to use it for weather forecasting. At this time, Americans reluctantly sold the machine to us, but they created a stinging scene. According to Yang Xuejun, a technician at the time, the room where the supercomputer was put was monitored and maintained by the Americans for 24 hours and the Chinese were not allowed to go in. When 20 years later, in 2007, at the International Computer Annual Conference, it has become a national defense science and technology
