The presence of a cathode bias resistor and bypass capacitor is not an indication of class A operation. 在场的情况下阴极偏置电阻和旁路电容不能说明A类作业。
The cathode bias potential mainly affects the crystallinity of the films. 阴极偏压主要影响合成薄膜的结晶状况;
Meanwhile it is testified that cathode emissive area and grid bias are the most direct effective factors. The experimental results lay a foundation for accommodation of welding every specification material at single emissive area in using EBW welder. 同时验证了阴极发射面积和栅偏压是电子束束斑直径大小最直接的影响因素,该结果为适应电子束焊机在单一发射面积条件下适应各种规格材料的焊接奠定了基础。

These disadvantages can bo overcome by the use of delay readout and pulsing the cathode with suitable bias potentials. 为了克服这些缺点,可以用在阴极上加适当的偏压脉冲,并延迟读出的方法。
