摘　　要：最大功率传输定理是电路理论教学中不可缺少的内容。在电路教学过程中,多次遇到过通过调节线性含源一端口部网络内部的某个参数来实现端口负载获得最大功率的问题,这样设计的问题是容易引起学生对定理的误用。本文通过几个具体问题的分析,得出最大功率传输定理的应用前提,指出教学中应注意的问题。The maximum power transfer theorem is an important part of electric circuit theory. In teaching this course, the students often required to solve such problems that maximize the power of the load at the port of linear active one port network by adjusting some parameter in the one port network. Such problems probably lead students to misuse the maximum power transfer theorem. This paper analyzes several examples deeply and points out the prerequisite of applying the theorem.
