| 摘 要： | 从传输线模型出发，分析了二平行直导线间串扰的低频模型有效性，得出允许3dB误差的条件下，低频模型在工程计算串扰中的电学短线和频率足够小的具体限值；同时分析了端接阻抗大小对串扰耦合的影响。对电磁兼容性中的串扰耦合的工程应用有实际指导和参考意义。

| Abstract: | The validity of low frequency model of crosstalk between parallel lines in engineering calculation is studied by making a comparison between transmission line model and the low frequency model. The specific condition is given for errors less than 3dB when estimating crosstalk using the low frequency model. The influence of terminal impedance to parallel lines on the crosstalk are also presented. The results are helpful to the engineering application on the electromagnetic compatibility. |

| Keywords: | low frequency model electric short line terminal impedance influence crosstalk |
