| 摘 要： | 基于一种新的描述回击通道底部电流的脉冲函数模型，利用偶极子法对距离回击通道底部不同距离处的LEMP进行了计算，把几种闪电回击的工程模型的计算结果与实测结果进行了比较，表明MTLL模型能够与实际结果更为吻合。

| Abstract: | Dipole technique is used to calculate the lightning electromagnetic pulse fields of different distance from lightning channel base on basis of a new pulse function which is used to describe channel base current. The results calculated from several kinds of return stroke engineering models are compared with the measured results, which shows that the result of MTLL model is in agreement with the real fields. |
