等值电路法列写线性网络的状态方程

本文介绍一种手算时用等值电路编写线性网络状态方程的方法。优点是不必列任何方程式，尤其是可以省略消去非状态变量的复杂计算过程。提出一种用检查“量纲”的办法，核对计算是否有误，以便及时纠正。

Linear Network State Equation Written by Means of Equivalent circuit

A method to write linear network state equation is intreduced by means of equivalent circuit. One of the advantages is that it is unnecessary to write any equations, and especially the complex calculating process of the non-state variables can be omitted. A method is proposed to check the dimension so as to determine whether it has any mistakes,it there is any, it can be corrected in time.
