摘要
本文从距离矩阵出发,结合分子中各原子的支化度,产生一种新的拓扑指数Y_X,并将它用于研究饱和链烃类化合物的理化性质,获得了比较满意的结果。与其它已有的拓扑指数比比较,该指数具有良好的结构选择性和相关性。
In this paper, based on distance matrix and branch vertex of atomes in a molecule, a new topological index (Y_X) has been developed to be used in research on physical and chemical properties of alkanes.It is concluded that this index bears good structure selectivity and relativity when the results from index were compared with that of other ones.
