摘　　要：为深入分析电子设备电磁敏感度测试中的容性脉冲干扰耦合方法,利用多导体传输线理论建立了耦合装置的计算模型及其方程.针对模型各部分不同的物理特性,结合使用解析、数值计算和实验数据推导的方法,获得了其各自的单位长度参数,进而通过参数整合建立起各部分共地的2n端口传输矩阵组合,以及包含激励源和终端负载的传输线方程组.验证实验表明,基于多导体传输线模型的计算结果与实验结果符合较好,该模型可用于预测容性耦合试验在电子设备端口产生的脉冲干扰强度及波形.An MTL （multi-conductor transmission line） model of the capacitive coupling clamp is developed to analyze the capacitive pulse interference injection method in the electromagnetic immunity test. According to different physical characters, the per-unit-length parameters of each part in the model are obtained by the analytical or numerical method as well as by deriving from experimental data. Then the 2n matrix and its equations are constructed. The solution of the MTL equations show a good agreement with the experimental results. The model can be used to predict the interference pulse entering the equipment.
