摘　　要：针对电路的等效变换,总结出两个性质:①如果两个电路等效,在两个电路的某些端钮(或端口)连接相同的任意电路,则得到的两个新电路也是相互等效的;②对两个电路,如果在两个电路的某些端钮(或端口)连接相同的任意电路,所得到的两个新电路是相互等效的,则这两个电路等效。利用该性质分析有关等效电路的问题,可达到事半功倍的效果。通过举例说明了该方法在电路分析中的应用。For the equivalent transformation of the circuit,two properties are summarized:①If two circuits are equivalent,the same arbitrary circuit is connected at some terminals(or ports)of the two circuits,then the two new circuits are also equivalent to each other.②For two circuits,if the same arbitrary circuit is connected at some terminals(or ports)of the two circuits,the two new circuits are equivalent to each other,then the two circuits are equivalent.Using these properties to analyze the problems about equivalent circuits can achieve twice the result with half the effort.Examples are given to illustrate the application of the method in circuit analysis.
