摘要
对我国土家族、瑶族青年人体头发中钙、镁、铁、锰、铜、锌、铬等７种金属元素进行了测定。用聚类方法对元素含量的综合指标进行了考查、比较研究。结果表明，土家族与瑶族青年人体头发中这７种元素的综合指标存在明显的差别。
In this paper, the concentrations of five trace elements and two common elments existing in the hair of young people from the Tujia Nation and Yao Nation were determined by inductively coupled plasma atomic emission spectrometer (ICP AES). A Data matrix of concentration of elements existing in the hair from two nationalities is evaluated comprehensively by using cluster analysis with satisfactory results which shows that there is considerable difference between these notionalities.
