火花预处理是提高真空介质强度的有效措施之一。本文研究了不同非均匀电场和不同阳极材料下真空放电条件下击穿电荷的变化规律，并讨论了基于阳极加热和阴极加热的击穿电荷变化机理。实验结果表明，在基于阳极加热的BD情况下，差距距离越长，获得最大介电强度所需的BD电荷越大。另一方面，在基于阴极加热的BD的情况下，最大介电强度的BD电荷小于基于阳极加热的BD的情况。从这些结果中，我们可以估计最佳BD电荷的火花调节在真空中。
Spark conditioning is one of the effective measures to improve the dielectric strength in vacuum. In this paper, we obtained the breakdown (BD) charge dependence for spark conditioning in vacuum under various non-uniform electric field and anode materials, and discussed the BD mechanism in terms of BD based on anode heating or cathode heating. Experimental results revealed that, in the case of BD based on anode heating, the longer the gap distance was, the larger the BD charge to obtain maximum dielectric strength was. On the other hand, in the case of BD based on cathode heating, the BD charge for maximum dielectric strength was smaller than that in the case of BD based on anode heating. From these results, we can estimate the optimal BD charge for the spark conditioning in vacuum.
