摘　　要：研究了双绞线的场线耦合模型,对外部电磁脉冲以及双绞线进行了建模。研究了在电磁脉冲激励下双绞线的终端响应。基于传输线理论,使用场线耦合模型,在远场强电磁脉冲入射的情况下,求解了电磁脉冲干扰信号耦合对双绞线终端的响应。最后,分析了不同终端阻抗对双绞线终端响应的影响。A field-line coupling model of twisted pair was theoretically investigated. The external electromagnetic pulse （EMP） and twisted pair model were established. The terminal response of twisted pair under EMP excitation in frequency domain was studied. Based on transmission line theory, the field-line coupling model of twisted pair was used for calculating the interference coupling response of twisted pair under strong EMP incident. Coupling terminal current of twisted pair with different terminal impedance was analyzed.
