摘　　要：主要讨论雷直击建筑物时雷电流在防雷系统中的分布特性,介绍利用计算机进行数值计算的方法。通过典型算例、传统的电磁暂态计算程序——EMTP的计算结果和利用清华大学高压实验室的冲击大电流发生装置,对此结构模型进行模拟试验,将3种结果进行比较,从而验证了本研究所编制的计算机程序的正确性。为进一步研究室内电磁场的暂态分析做好基础。Discussing the distributing characteristics of the lightning current in buildings and in the lightning protection system occurred transiently at a shock by a lightning-bolt. A numerical computerizing method is also introduced. Through three ways,a typical calculating method,a traditional transient programming,a simulating experiment on a structure model,which is conducted in the High Voltage Laboratory of the Qin Hau University,and in comparison with them,a perfect accord is obtained and the correctness is manifested of the program. It has apparently laid a foundation for a further study of transient state of magnet field in a building.
