1.引言1.1总的注意事项充气管的特性和(高)真空管的特性完全不同。因为管压降几乎与通导的电流大小无关,并且在放电开始之后,栅极一般是没有控制作用的,所以通过管子的电流主要取决于所加的电压及电路参量。在充气管中通常使用汞蒸汽。管子中的气压随凝汞温度变化得很快,并且影响管子的电
1. Introduction 1.1 General Precautions The characteristics of an inflatable tube are quite different from those of a (high) vacuum tube. Since the tube voltage drop is almost independent of the current conducted and the gate is generally not controlled after the start of discharge, the current through the tube depends mainly on the applied voltage and circuit parameters. Mercury vapor is commonly used in inflatable tubes. The pressure in the tube varies rapidly with the mercury temperature and affects the tube's electricity
