摘要

对水中非均匀场中的预击穿事件进行了实验研究。观察到以亚音速传播的分支树突和超声速等离子体通道的形成。研究发现，在去离子水中，加热对排放通道的形成和发展没有影响。进一步表明，放电次数为10/sup -4/ ~ 10/sup -3/时的EHD(电流体动力学)事件在不改变放电动力学的情况下影响慢枝的发育。

The effect of heating and EHD events on breakdown in water

Prebreakdown events in a nonuniform field in water were studied experimentally. Branching dendrites propagating with subsonic velocities and thin supersonic plasma channels were observed to form. It was found that, in deionized water, heating has no effect on the initiation and development of discharge channels. It is further shown that the EHD (electrohydrodynamic) events for discharge times of 10/sup -4/ to 10/sup -3/ affect the development of slow dendrites without changing the discharge dynamics.<>
