雷电电磁场在建筑物内外分布的数值计算

Numerical Calculation of the Distribution of Lightning Electromagnetic Field Inside and Outside the Building

采用数值计算方法，对雷云对地放电所伴随的雷电电磁场在建筑物内外的分布进行了计算．解决了用解析解难以计算的介质突变等问题，得出了建筑场内外的电磁场的强弱分布，这对于计算机和电子设备的防雷及抗干扰有着重要的理论和实际应用意义．

In this paper, a numcrical method is put forward to calculate the distribution of lightning electromagnetic field inside thc building caused by lightning stroke. It has solved the problem of great changes in mcdium, which is dimcult to deal with in analyne solution. Thc distribution of clectromagnetic field intensity insidc and outside the building under the lightning stroke are given. It is significant in theory and prachce for thc lightning protCcting and ant-interference of the computors and elcctronic cquipmcnts.
