英语翻译
By the late 50s though,as vacuum tubes were being replaced by bipolar junction transistors (BJT),tubes survived only in niche applications,such as wideband distributed amplifiers,as the BJT is basically a low to medium impedance device,and as such,is not very compatible with distributed amplifier theory.

但是到50年代后期,由于真空管被双极性接面电晶体(BJT)所替代,真空管只在小的应用欢迎幸存,如多频分布式放大器.因为BJT基本上是低阻抗到中阻抗的设备,由于此,不太兼容于分布式放大器原理.
尽管到了五十年代后期,伴随着真空管被双极结晶体管取代,于是真空管仅幸存于小环境应用中,例如应用于宽带(沿线)分布式放大器上,因为双极结晶体管基本上是一种中间阻抗装置,所以与分布放大理论不是很协调。
