摘　　要：应用拓扑学理论,提出一种新的空间机构有级边拓扑描述方法,推导出有级边拓扑图的几个重要的矩阵:邻接矩阵,关联矩阵和环路矩阵。在此基础上,分析了矩阵的性质,空间机构运动副轴线位置关系对运动特性的影响,给出了空间机构的结构描述特征字符串。Abstract： A new method ior describing spatial mecnamsms in topological grapn grauc terms of the topology theory, and three important matrices in topological graph with grade edge, including adjacency matrix, incidence matrix and circuit matrix are derived., Based on the above-mentioned, the characteristic of those matrixs and the effect of the position relations of kinematic pairs axes in spatial mechanisms on motion characteristic are analyzed, and the character strings of structure description for spatial mechanisms is promoted.
