| 摘 要： | 主要讨论了二端口网络的特性阻抗与影像阻抗。特性阻抗和影像阻抗是在电路分析中二端口网络部分引入的概念。在教学过程中，笔者发现，对于特性阻抗，不同版本的教材有两种不同的定义，有的认为特性阻抗与影像阻抗是同一概念。为了弄清楚二者的关系与区别，笔者翻阅了相关书籍并请教了部分专家，针对特性阻抗的两种不同定义，说明了自己的观点，澄清了一些比较模糊的概念。

| Abstract: | The characteristic impedance and image impedance of two-port networks are discussed in this paper. The characteristic impedance and image impedance are introduced in two-port networks of circuit analysis. It has been found that there are two kinds of definitions on characteristic impedance in textbooks. Some textbooks treats characteristic impedance and image impedance are the same in concept. Such inconsistency in definition can often cause confusions. This paper has distinguishes characteristic impedance and image impedance after reviewing literature and consulting experts. |
