摘　　要：在微波传输线理论教学中,由阻抗确定反射系数是一个重要的知识点。教科书一般只针对负载阻抗为实数的情况进行讲解,但是在实际工程运用中常会遇到负载阻抗为复数的情况。本文运用传输线理论阐述了阻抗和反射系数之间的关系,并分别应用功率方程和功率波的分析方法推导了复数阻抗条件下的反射系数修正公式。In the microwave transmission line theory teaching,reflection coefficient derived from the impedance is an important point of knowledge.Textbooks generally only explain the load impedance is real case,but the situation where the load is complex impedance is often encountered.In this paper,the relationship between impedance and reflection coefficient is expounded by transmission line theory,and the correction formula of reflection coefficient under complex impedance condition is deduced by using power equation and power wave analysis method respectively.
