传输线分布参数模型与物理模型

The Comment on Distributed Parameter Model and Physical Model for Transmission Lines

本文详细分析了传输线的分布参数电路模型与真实的物理电路模型之间的关联,同时对均匀传输线模型给出了明确的适用范围。如此,可以解决"电磁场"和"电磁兼容"等课程中经常令学生困惑的问题,对正确理解二端口模型的本质,提高理论素养大有裨益。

In this paper, the relationship of distribute parameter model to physical model for transmission lines in detail is given. Meanwhile, the limits permitted by the parameter model are also defined. So, problems that often puzzle the college students and graduate students can be solved in the course of Electromagnetic Fields and Electromagnetic Compatibility. It is useful for them to deepen comprehension to two-ends model, and improve the theoretic attainments as well.
