传输线方程是微波传输线理论中最基本的方程之一，是微波传输线理论的基础方程。本文从教学中发现的等效电路不对称性出发，深入考虑传输线的物理对称性，以分布参数为基础，建立了 T 型和П型两种对称的分布参数等效电路，并利用电路中的基尔霍夫定律，分别推导出了形式相同的传输线方程。本文推导可供“微波技术”课程的教师和学习者作为参考。

Transmission line equation is of the fundamental equations in the theory of microwave transmission line. Noticing that the equivalent circuit employed in books is not symmetrical,this paper presents T style and П style symmetrical equivalent circuits based on the distributed parameters of transmission line according to the physical symmetry of the transmission line. The transmission line equation is derived from these two equivalent circuits sepa-rately by using Kirchhoff's law. The derivation in this paper can be used by teachers and learners as references when performing relating courses.
