The effect of charges remaining on a dielectric plate upon the 50% impulse surface flashover voltage U_ (50) in the non-uniform field (rod-plane gap) is investigated.

针对不均匀电场(棒-板间隙)中绝缘板上残余电荷对50%冲击闪络电压u _(50)的影响做了一些试验研究。

In this method, the non uniform media is approximated by multi layer dielectric media and modeled as a cascaded transmission line.

这种方法将一维不均匀介质用多层介质近似，并进一步用级联的传输线模型等效。
