摘要
本文建议一种计算直接雷击时建筑物内脉冲电磁场的新算法。雷电脉冲电磁场的计算公式直接从时变电磁场的泛定方程导出，能计及各种分量场的影响．在对这些计算公式进行离散化处理之后，电场强度和磁感应强度的数值解能够被获得。为了检验所建议算法的有效性，本文给出了若干算例。
This paper proposes a new algorithm for calculation of the pulse electromagneticfield in a building struck by lightning. The calculation formulas are derived from the basicequations of tboe-varying electromagnetic field, in which dmerent kinds of field compo-nents are taken into account. With a discretisahon for the calculation formulas, the numer-ical solutions are obtuined to electric field strength and magnetic flux density respectively.Then, the calculated results are given to confirm thc validity of the proposed algorithm.
