阴极碳化 meaning in English

cathode carbonization

This article introduces briefly the process of design and characteristic of structure of db930 tube and discusses the main problems of technology and technique which was met during the manufacture and the measures having been adopted are emphatically . it discusses the solve measures in following six aspects : the filament current is too large , carbon deposits during the carbonizing of cathode , the capacitance between the first grid and the second grid is too large , transpiring happens inside the tube , the insulation resistance between the electrodes is too lower when the filament is on and the ability of bearing high voltage is too lower
本文简略地介绍了db930的设计过程及其结构特点,重点论述了在试制过程中遇到的主要工艺技术问题及解决问题的措施,围绕解决灯丝电流大、阴极碳化时积碳、一栅和二栅之间的电容大、管内蒸散、热态时极间绝缘低、耐高压的能力差等六个方面的问题进行了论述。
