摘要
利用等离子体发射光谱法对中国苗族、畲族青年人发中７种金属元素的含量进行了测定，用聚类分析方法对７种元素含量的综合指标进行考查，比较研究发现这两个民族的青年人体头发中７种元素含量的指标在整体水平上存在明显的差别。
The concentrations of 7 metal elements in the human hair from Miao and She nationalities were determined by analysing the inductively coupled plasma atomic emission spectrometer(ICP-AES).A data matrix of concentrations of 7 metal elements in the hair from Miao and She nationalities is evaluated by using cluster analysis with satisfactory results comparing.
