摘　　要：　提出求证电阻星形联接和三角形联接之间的等效变换关系的一种新方法,利用外接电阻或者外接电源的方法,将电阻星形联接和三角形联接之间的等效转化为二端网络电路之间的等效问题,在简化电路的分析基础上,求解代数方程组,从而获得电阻星形联接和三角形联接的等效变换关系式.In the paper, new method is successfully extended to construct the demostration of equivalent convert between Wye-connected and Delta-connected in rsistence circuts(BWDRC). the equivalent BWDRC are altered to the equaivalent both two-leader network by connected in rsistence or connected in voltage(current) source . The formula of the placement BWDRC is obtained by solving algebraic equations on the base of simplify and analyze the circuit.
