摘　　要：给出了冠图(G1·G2)·G3的Wiener指数W((G1·G2)·G3),得出了W((G1·G2)·G3)与三个图的边数和顶点数有关,且与G1的结构有关,而与G2、G3的结构无关.We gave the Wiener index W((G1(?) G2)(?) G3)of the corona graph(G1(?) G2)(?)G3,and obtain that W((G1(?) G2)(?)G3)is related to the number of edges and vertices of the three graphs,and is related to the structure of G1,but not to the structure of G2 andG3.
