摘　　要：讨论了图的Sei del矩阵特征值和邻接矩阵的特征值之间的关系;证明了图的Sei del矩阵的主特征值可从它的邻接矩阵的主特征值和相应的特征向量而得到.An eigenvalue of real is called main eigenvalue if it has an eigenvector the sum of whose entries is not equal to zero. In this paper, relations between the main eigenvalue and associated eigenvectors of adjacency matrix and Seidel matrix of a graph are investigated.

关 键 词：图谱 Seidel矩阵 主特征值
