摘要

将经验击穿定律推广到非均匀场条件下击穿电压的评估。研究了压力和间隙长度的影响。结果表明，在非均匀场条件下，击穿电压与分子密度(压力)之间的指数关系不受影响。然而，在非均匀场结构下，不同的气体具有不同的行为。特别是，由于磁场的不均匀性，大大降低了氟利昂的破坏电压

Non-uniform field breakdown of gases

The empirical breakdown law is extended to the evaluation of breakdown voltage under nonuniform field conditions. The effects of pressure and gap length are investigated. It is shown that, in nonuniform field conditions, the exponential relation between breakdown voltage and molecular density (pressure) is not affected. However, the different gases do not have the same behaviour under nonuniform field configuration. In particular, the disruptive voltage of Freons is greatly reduced by the nonuniformity of the field.<>
