摘　　要：端口伏安关系在电路分析中具有非常重要的地位;网络的端口伏安关系,一般在端口外加电压源或电流源,通过测量或计算方法获得;单口网络串联或并联后其端口伏安特性可通过图解法或解析法加以合成;端口伏安关系是判断两个单口网络等效的依据,其原理还可推广到三端网络及双口网络.The Volt-ampere re source or current source, generally when one-port network series or para lation of Port Play an important the volt-ampere relation can b llel connection, its volt-ampere role in arcuitry analysis. Using an applied voltage e obtained thtough measurement or computation; relation of the port can be compound by analytical method or by graphic solution. The volt-ampere relation or U-I relation of port is one of basic gist for solving general circuitry question, also can judge two one-port-network whether or not equivalent. This equivalent principle of one- port-network can be extend to three-terminal-network and two-port-network .
