摘　　要：平面机构运动链的同构识别是运动链再生创新设计的重要组成。文中基于平面机构运动链的结构特征,提出了解决此问题的新方法-标号法。首先对运动链各构件按一定的规则进行标号,进行规范化处理,然后用规范化缩杆邻接矩阵表示该运动链图的连接关系,根据两运动链的缩杆邻接矩阵是否相同来识别两构件是否相似。Isomorphism indentification of planar mechanism kinematic chains is important composing in the regenerative innovation design of kinematic chain. Based on the structural features of planar mechanism, a method called mark is presented. First each components of kinematic chain are labeled according to the rules, then the contracted link adjacency are used for denoting the connections of Kinematic chain diagram. The different component＇s Isomorphism can be distinguished according to the two contracted link adjacency whether the same.
