20世纪50年代初，美国某军事科研部门在研制一种高频放大管的时候，科技人员都被高频率 放大能不能使用玻璃管的问题难住了，研制工作迟迟没有进展。后来，由发明家贝利负责的 研制小组承担了这一任务。上级主管部门在给贝利小组布置这一任务时，鉴于以往的研制 情况，同时还下
In the early 1950s, when a military scientific research department of the United States was developing a high-frequency amplifier tube, scientists and technicians were struggling with the problem of using glass tubes with high-frequency amplification. There was still no progress in the development of the research. Later, the research team led by inventor Bailey assumed this task. When the higher authorities arranged this task for the Bailey team, given the previous research and development,
