smith阻抗圆图演示，可以用于微波无损耗传输线教学。也可用于处学delphi者熟悉tcanvas控件使用。-impedance Chart demonstration can be used for microwave transmission lines without loss of teaching. Also can be used to learn delphi TCanvas familiar with the use of controls.

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
