High-voltage (HV) discharge phenomena, which appear in the working process of electron beam bombarding furnace (EBBF), may result in failure of HV silicon rectifier stack (SRS) in the worst cases.
电子束轰击炉运行过程会产生高压放电现象，严重时可能损坏高压整流硅堆。

It has been verified in this paper, by theoretical analysis with two-phase fluid mechanics and hydraulic tests, that decreasing surface roughness in a wade stack can not increase critical discharge.
