| 摘 要： | 直接求解无损传输线方程所得的通解包含了正向行波和反向行波两部分。本文在此基础上根据行波在传输线上多次反射的现象。推导出了在阶跃激励下无损传输线上任意一点的解析解，并对线上电压、电流的稳态值作了讨论。同时，该方法更加清晰地描述了线上电压和电流行波的暂态过程，更能体现出通解的物理含义。

| Abstract: | The general solutions that are obtained from lossless tansmission line equations are made of forward and backward travelling wave. In this paper , the analytical solutions of lossless transmission line equations are calculated in accordance with the phenomena of travelling wave＇s reflection time after time, and steady - state solutions of voltage and current on lines are analyzed. In addition the proposed method describes transient state process of travelling wave of voltage and current distinctly and indicated the general solutions＇ signification demonstrably. |
