摘　　要：本文分析了先导发展的过程， 提出了等效电容的概念； 进而在考虑了先导发展影响的基础上， 提出了适用于极不均匀场间隙伏秒特性的计算方法； 与实测结果的比较表明， 计算结果是可信的。From the analysis of the leader propagation,the concept of equivalent capacitor is put forward;in consideration of the effect of the leader propagation,a theoretical method to calculate the U? ?t curve is proposed.The calculated results and the measured results are in agreement with each other except for a few points in the range of time lag less then 1μs
