摘　　要：顶点度距离是图的一个关联顶点度和顶点间距离的局部指标.针对一类特殊的多圈图——轮图,研究了其顶点度距离及极值问题.结果表明,轮图的顶点度距离在图的中心点取得最大值,在其轮上的顶点处取得最小值.The vertex degree distance is a local index of a graph that relates vertex degree and distance between vertices.For a special class of multicyclic graphs——wheel graphs,the vertex degree distances and extreme values problem are studied comprehensively.The results show that the vertex degree distances of the wheel graph reach the maximum at the center of the graph and the minimum at the vertices on its wheel.

关 键 词：顶点度距离 度距离 最值 轮图
