摘　　要：建立了混和图的特征值与匹配数、直径以及拟悬挂点数的关系,推广了简单图上若干关于特征值分布的结论.In this paper, we establish some relations between the eigenvalues and matching number, diameter, and the number of quasi-pendant vertices of mixed graphs, which extend some known result of simple graphs on eigenvalues distribution.

关 键 词：混和图 特征值 匹配数 拟悬挂点
