摘　　要：研究了电路理论中有关置换定理的使用条件，强调置换定理必须在一定条件下才能使用，这个条件就是置换前、后的电路必须具有唯一解。当线性非时变电路中含有某种受控源时，可能不存在唯一解。Condition under which the replacement theorem is applied in network is studied.It is emphasized that a network using the replacement theorem must satify a certain condition:there must exist a unique solution before and after the network is replaced.If a linear nontime varing network containing a certain controlled source does not exist a unique solution,its response can not be worked out by using the replacement theorem.

关 键 词：线性电路 电路理论 置换定理
