氯代烃的相对危险性分级

Relative risk classification of chlorohydrocarbons

选用分子结构拓朴指数，物理化学性质参数和毒性毒理指数共１１种作为危险性分级参数。采用模糊聚类相似系数法，Ｑ型系统聚类相似系数法和欧氏距离倒数法，以及平面投影对应变换法进行最终综合评判分析。将２４种氯代烃的大气环境事故中的相对危险性分为轻度、中度、高度和极度四个等级。

A method which estimates the relative risk classification of hazardous and dangerous chlorohydrocarbons has been advanced by means of fuzzy cluster analysis,Q type system stepwise cluster analysis, correspondence transformation of plane projection method and finally the comprehensive discrimination method including 11 kinds of risk classified parameter which are molecular connectivity index,physical and chemical properties and hazardous index The relative risk classification of 24 kinds of Chlorohvdrocarbons for air environmental accidents can be divided four classes i. e. light. middle. high and extreme.
