传输线的工作状态波形，包括行波和驻波，当参数改变时，传输线的工作状态也因此而改变-The operating state of the waveform of the transmission line, including traveling wave and standing wave, when the parameter is changed, the working status of the transmission line can also be changed

自己改编的代码，可以进行基本参量的计算（归一化阻抗和导纳，驻波比、行波系数和反射系数等），鼠标取点绘制并计算相关特性阻抗，计算距离负载d处的输入阻抗，单枝节匹配和双枝节匹配，圆图的绘制、保存图像等。且整个过程可视化~-Own adaptation of code can be calculated basic parameters (normalized impedance and admittance, VSWR, traveling wave and reflection coefficie
