The temperature had great effect to the triodes performance and made the quiescent operation point in circuitry unstable.

温度对三极管的性能影响较大，使得电路中的静态工作点出现不稳定现象。

In the early 1950s, a new technology based on semiconductor construction would replace triodes with transistors, in cases where low-power amplification was needed.

在上个世纪五十年代初期，基于半导体结构的新技术，在需要低功率放大的情况下可用晶体管替换三极管实现这一功能。
