摘　　要：在研究了平面机构运动链结构不变量的基础上,基于缩杆邻接矩阵提出了3个新的运动链结构恒量序列,这些恒量序列将杆的级别、运动副数目以及各杆的连接关系考虑在内。并进一步提出了以它们对运动链进行同构识别的缩杆邻接矩阵法,该方法具有操作简单、可靠性好、识别效率高等特点。We study the structural invariants of kinematic chains of a planar mechanism and then propose mree new structural invariant sequences of the kinematic chains which are based on contracted link adjacency matrices and for the purpose of identifying their isomorphism. The invariant sequences include the configuration degree of links, the relational degree of contracted links and the relational degree of configuration links. The method is easy to use and does not involve complicated mathematical calculation, and is suitable for computer programming. Its algorithm is efficient and takes less space.
