摘要 扩展的BLT方程主要是用来计算电磁场对传输线上负载的干扰,是电磁拓扑理论的基石。本文对一个简化的空间辐射电磁场对平行双线耦合的模型进行分析,重新推导了该模型情况下的BLT方程的表达形式,并用软件仿真验证理论计算结果。这种方法可以用来计算和预测机车电磁兼容中瞬态电磁场对信号线或电力线的干扰。 The extended BLT equation was used to calculate the coupling effects of eletromagnetic（EM） field on the load of transmission line and it was considered to be the foundation of electromagnetic topology（EMT）.This article analysed a simple model which described how EM field coupled to a parallel transmission line.Transmission line theory was used to deduce the BTL equation for this model according to the method of deducing the original BLT equation.Then the author used software to simulate and validate it.In rolling stock EM coupling area,this method was applicable for calculating and predicting interference on signal line or power line which was caused by transient EM field.
