电介质的击穿(breakdown of dielectric medium)电介质只能在一定的电场强度以内保持绝缘的特性。当电场强度超过某一临界值时，电介质变成了导体，这种现象称为电介质的击穿，相...

结果表明，电介质的击穿并不总是发生在电荷的注入过程中，也可以发生在空间电荷的脱阱过程中。
The experimental results show that not only space charge injection but its detrapping also makes samples breakdown.
因此击穿电压的检测必须重视电介质击穿现象的电参数值的测量。
The exact determination of the breakdown voltage must therefore be attached to the measurement of an electrical value characteristic of the dielectric breakdown phenomenon.
击穿性能是电介质材料最基本的要求，提高材料的电气强度是电介质研究最为重要的任务之一。
Breakdown property is the basis requirement to dielectric and the improvement of the electrical strength is one of the most important works in dielectric research field.
