在阴极的工作温度下,测量氧化物阴极静态情况下的发射能力是研究氧化物阴极时一个很困难的问题。因为发射电流经过氧化物阴极的涂层就引起涂层的过热而使阴极损坏。已知的求氧化物阴极发射能力的方法,用于大量地测试电子管时是太复杂太费事了。 为了大概估计氧化物阴极在工作温
Measuring the emission capacity of oxide cathodes under static conditions at the cathode operating temperature is a very difficult issue for the study of oxide cathodes. The cathode is damaged due to overheating of the coating as a result of the emission current passing through the oxide cathode coating. Known methods for seeking the oxide cathode emission capability are too complicated and complicated to test the tube in large quantities. In order to roughly estimate the oxide cathode temperature at work
