摘　　要：在雷电防护中,一般需要了解精确的雷电电磁场,因此,雷电电磁场的研究具有重要的现实意义。文章在假设大地为理想导体的情况下,从Maxwell方程组出发对雷电电磁场的空间分布进行计算和分析,并最终推导出雷电流周围的电磁场表达式,为进一步对雷电防护提供理论基础。In the lightning protection, accurate electromagnetic field of lightning must be got. So the research on the electromagnetic field of lightning has been important. Based on the assumption that the earth is ideal conductor, the spatial distribution of lightning electromagnetic field with Maxwell＇ s equations calculated and analyzed in this article. And the electromagnetic expression is deduced, which may provide the theoretical foundation for the lightning protections.
