摘　　要：通过把图论的矩阵理论的性质应用到平面机构学中构建出新的特性矩阵,提出平面机构系统特性矩阵的构建方法,还定义了构件关联矩阵和运动副关联矩阵,同时通过矩阵主对角戏谱的概念说明平面机构矩阵中主对角戏谱包含的具体物理含义。In this article,the matrix properties based on graph theory are applied to the planar mechanism. Thus,the new characteristic matrix is constructed. In addition,how to set up a systematic characteristic matrix in the planar mechanism？ This question is also illustrated. What＇s more,both the correlation matrix and pair correlation matrix are defined. Based on the main diagonal spectrum of the matrix,the concrete physical meaning of main diagonal spectrum in the matrix of planar mechanism is illustrated.
