| 摘 要： | 均匀传输线可以采用电磁场理论来建立分析模型。而电路理论在电磁场理论基础上、加上集中参数假设,也可建立均匀传输线的分析模型。本文在推导出两种分析模型基础上,论证了两种模型的一致性,并从场和路两方面剖析了传输线传播特性与其周围媒质传播特性的差异、以及影响传输线传播特性的因素。本文的探讨,有利于从事"电路理论"和"电磁场"课程教学的教师加深对均匀传输线传播特性参数的理解。

| Abstract: | The uniform transmission line can be analyzed by electromagnetics. It also can be analyzed by electric circuit theory which is based on electromagnetics and lumped circuit assumption. Based on the derivation of two analyze models, this article proofs the agreement between the two models. The differences of the transfer characteristics between the transmission line and the medium are analyzed, and the influence factors to the transfer characteristics of a transmission line are analyzed. This research is helpful to the teachers who are teaching electric circuit theory and electromagnetics to understand the characteristic parameters of the uniform transmission line. |
