摘　　要：用两种数值分类方法对19种瓶装饮用水所含挥发性有机物(VOCs)进行聚类分析,EDC法的分类选用欧氏距离为相似性测度,聚类采用重心法;CBM法选用绝对距离与中位数法.结果得到两系统聚类树形图及一统计量表,表明水样可分为四类和定量分级评价为三个等级:不合格(水样M6)、合格(水样M2、D4)、较好(其他16种水样).聚类分析能同时实现瓶装饮用水的分类与定量分级评价.A cluster analysis of 19 bottled drinking water samples was studied based on their volatile organic compounds(VOCs) by using two numerical classification methods. Method EDC used Euclidean distance as similarity measure and centroid method as clustering algrithm;Method CBM used absolute distance and median method. The result showed that 19 water samples could be classified into 4 groups and quantitively evaluated as 3 grades:unqualified(M6),qualified(M2,D4),better(other 16 samples).Cluster analysis could be used to classify and quantitively grading evaluate on VOCs of bottled drinking waters.
