摘　　要：建立了雷电参数的计算模型,其中水平磁带与垂直磁带的消磁长度差与雷电流最大陡度成线性关系。在介绍和分析磁带测量原理的基础上,提出了统计雷电参数的方法。考虑到工程应用的恶劣环境,提出将磁带封装在PVC塑料管中的方法,并进行了实际测量;拟合了适用于雷电流幅值分布的数学表达式。建立了一种简单易行的分析和统计方法,以期为我国大规模雷电参数及其分布的统计研究提供参考。A lightning parameter calculation model is built in which the difference between the length of erased magnetic record in horizontally arranged magnetic tape and that in vertically arranged magnetic tape is in linear relation to maximum gradient of lightning current. Based on the presentation and analysis on the measurement principle of magnetic tape, a method for the statistics of lightning parameters is proposed. Considering the harsh environment in engineering application, a method of packing magnetic tape in PVC tube is given and applied to actual measurement. The mathematical expression suitable to the amplitude distribution of lightning current is fitted and a scientific, canonical statistical and analytical method that is easy to implement is put forward in the hope of providing reference for large-scale statistical research on the amplitude distribution of lightning parameters in China.
