凹顾真空电子技术的发展历史,人们往往想起1883年爱迪生在研究白炽灯性能时发现金属加热到足够高的温度时能发射电子的爱迪生效应。1904年英国科学家弗莱铭在此基础上发明了真空二极管。但是,能把电子管造福于人类,开创电子学发展新时代的还 Despite the history of vacuum electronics, people often think of Edison’s effect of emitting electrons when the metal was heated to a sufficiently high temperature by Edison in 1883 to study the performance of incandescent lamps. In 1904 British scientist Fulai Ming invented the vacuum diode on this basis. However, the benefits of electronic tubes to mankind, creating a new era of electronics development also
