摘要
从距离矩阵出发,结合矩阵的数学运算,定义了1种新的拓扑指数SZ,并将它用于研究链烃类化合物的沸点,获得了比较理想的结果.与其他拓扑指数相比,该指数计算简单,具有良好的结构选择性和相关性.
A new topological index has been developed based on the distance matrix in this paper. It was used in study on boiling point of chain hydrocarbons. Compared with other topological index methods, it has better structural selectivity and correlation.
