摘要
通过分析分子图拓扑结构对物性的贡献,描述分子拓扑不变量的定量指标,以便详细地概括和综述Wiener拓扑指数的基本概念及性质。
The guantitative index of topological invariant for molecule is presented by analying the tribution arising from the topolagical stractare of molecule graphs. The basic concept and properties of Wiener topological index are outlined and reviewed in defail, and two methods for calculating Wiener index also presented.
