摘　　要：Wiener指数和Gutman指数是两个重要的拓扑指标,常用以刻画分子结构特性.假定Ln表示由n个六边形和2n个正方形构成的线性结构分子图,借助图的结构特点,确定Ln的Wiener指数和Gutman指数.Wiener index and Gutman index are two important topological indexes,which are commonly used to describe the characteristics of molecular structure.It is assumed that the molecular graph of linear structure is composed of n hexagons and 2n squares.With the structural characteristics of the graph,the Wiener index and Gutman index of L n are determined.

关 键 词：化学分子图 WIENER指数 Gutman指数
