A simple approach is presented to analyse a typical high frequency transistor stage.
本文介绍一种简便分析典型晶体管高频电路的方法。
Use single stage version to reach the temperature of 20 K is a difficulty for high frequency pulse tube cooler (PTC). Multi-stage version is a popular method to reach the low temperature.
单级高频脉冲管制冷机直接降低到20 K以下温区存在很大困难，采用多级方案是高频脉冲管制冷机获得更低温度的主要方法。
This technology is sensitive to minor structural damage on the early stage because of the high frequency scope of working frequency in the alternating electric field.
由于交变电场的工作频率高频范围，所以该技术对结构早期的细小损伤非常敏感。
