Ⅰ、电子管内残余气体压强测量的一般原理电子管内因真空度不高,会引起一系列问题,例如管子噪声增加,工作电压降低,阴极寿命缩短等等。因此,把电子管内残余气体压强测量出来,作为分析管子性能和合理确定管子制造工艺规范有重要意义。 Ⅰ, General Principle of Residual Gas Pressure Measurement in Electron Tube The vacuum inside the tube is not high, which will cause a series of problems, such as the increase of tube noise, the decrease of working voltage, the shortened cathode life and so on. Therefore, measuring the residual gas pressure in the tube is of great significance for analyzing the performance of the tube and for properly determining the specification of the tube manufacturing process.
