本文所叙,係改制雷达用的1B24式TR管,以自动调节3厘米波带的微波讯号的强度,以便用于各种雷达控制装置之中。在1B24式TR管中有两个主要电极,上面一个电极是尖端的,下面一个电极则是圆锥形而中空的。在中空的电极内另装一个所谓保活电极(keep-alive electrode)。此电极系连接 Described in this article is the use of a Type 1B24 TR tube for radar reconditioning to automatically adjust the intensity of the microwave signal in the 3 cm band for use in a variety of radar control devices. In the 1B24 TR tube there are two main electrodes, one above the electrode is the tip, one electrode is conical below the hollow. In the hollow electrode another so-called keep-alive electrode (keep-alive electrode). This electrode is connected
