| 摘 要： | 有损均匀传输线的电压、电流既是时间的函数,也是距离的函数,需要用分布参数电路模型分析.有损均匀传输线方程是偏微分方程,正弦稳态解的手算求解比较复杂.应用PSpice对有损均匀传输线进行仿真分析,可得到传输线上任一点的电压、电流的频率特性和正弦稳态波形.本文介绍了有损均匀传输线的PSpice模型和参数,通过实例说明了其应用方法,通过对比可知仿真分析比手算求解更清晰地阐明了物理概念.

| Abstract: | The voltage and durrent of lossy uniform transmission lines are function of not only time but also distance . Lossy uniform transmission lines is distributing parameter circuitry , the equation is a partial derivative equation. Sinusoidal steady - state solution is very complex for manual calculation. Simulation analysis of lossy uniform transmission lines by PSpice can gain every point voltage and current in the lines. This paper explains the PSpice model and the parameters of lossy uniform transmission lines and gives an example. Simulation analysis clarify the physics concepts more clear than manual calculation. |
