摘要/Abstract

摘要： 通过大地表面阻抗来计算雷电产生的水平电场(表面阻抗法), 并对其计算结果与斜波法进行了比较.最后指出这种方法适用于计算离雷击点较近处的水平场, 而此时用斜波法计算会产生较大的误差.

关键词: 电磁场, 水平电场, 表面阻抗法

Abstract: A new method by using the expression for the surfaceimpedance of the earth with finite conductivity presented, and the results of horizontal field calculated from wave tilt and surface impedance with exact expression is compared. The new method is suit for calculating horizontalfield generated by return strokes at distances as close as 200m, while these close ranges the use of the wave tilt expression can cause large errors.

Key words: electromagnetic field, horizontal field, surfaceimpedance method
