摘要
本文以Balaban在定义J指数时的距离度Sj为基础提出了一个表征烷基苯类化合物性质的信息拓扑指数Is.该指数如同信息拓扑指数Iz和Ix易于计算,与现有的一些拓扑指数相比较,无论对烷基苯的加和型性能(如标准生成热、摩尔折射度等)还是凝聚型性能(如沸点等)都是具有较好的结构选择性和性质相关性.
The paper gives a few information topological indices I_(s) of alkyl benzenes on the basis of distance degree S_(j) given Balaban. This index that is easy to calculate as information topological indices I_(z) and I_(x), is possessed of a good structure-selectivity and property-correlativity for either addition-property(such as standard heat of formation, molar refraction, etc.) or coacervation-property(such as boiling point, etc.) comparing with some extant topological indices.
