【Abstract】 Kirchhoff′s laws and the methods of circuit analysis are applied to identify isomorphism of kinematic chains. The equivalent circuit models of kinematic chains are established firstly, which make the topological relationships of kinematic chains equal to the topological restriction of circuits. Then the isomorphism judgment criterion based on the circuit analysis is obtained by applying the circuit laws and the method of branch current to the circuit models. Finally, the method is illustrated with several examples which show that this method is simple, reliable and convenient.更多还原
