Methods for the measurement of direct interelectrode capacitances of electronic tubes and valves 电子管极间电容的测量方法.第1次修改
It was tested on static characteristic parameter , including the interelectrode capacitance , voltage resistance and others . the test data are almost same as those of th558 . the design goal was achieved on static parameter 对样管的极间电容、耐压和静态特性参数进行了测试,测试结果与th558样管基本一致,静态参数达到研制目标。
During development db935 , the main responsibilities as follows : 1 . the db935 ’ s sizes , electrical parameters , interelectrode capacitance and the transmitter dynamic parameters must be same as those of th558 so that it can be applied to replace th558 在负责db935的研制工作中所做的主要工作如下: 1 、为使研制出的db935发射管能与进口的th558电子管互换使用, db935的外形尺寸、主要电参数、各电极间的电容以及整机动态指标均须与th558一致。
