| 摘 要： | 在Rand ic提出的分子支化度指数的基础上,引进了卤原子的电负性,提出了一种新的拓扑指数,并对饱和卤代烃在常压下的沸点与化学结构之间的关系进行研究,建立了回归方程,相关系数达到0.995,预测值与实验值基本吻合.

| Abstract: | On the basis of the molecular branching index of Randic,by adding Pauling molecular electronegative,a new molecular topological index was proposed and used to correlate between the chemical structures of haloalkanes and their boiling point at normal pressure.Regress equation was established,with the correlation coefficient of 0.995.This empirical data is consistent with the method by calculation. |
