| 摘 要： | 用原子吸收光谱法对青海土族、藏族和回族青年人体头发中的Ca、Fe、Zn、Cu、Mg、Mn和Cd等7种元素的含量进行了测定,采用概率神经网络方法进行了比较研究。研究表明,在3个民族的人发之间,7种元素含量的综合水平存在着较显著的差别,概率神经网络方法可以用于对这3个民族样品进行判别和预测,其预测结果优于F isher法或Bayes法。

| Abstract: | The concentration of Ca,Fe,Zn,Cu,Mg,Mn and Cd in the hair of young people from Tu、Zang and Hui nationalities of Qinghai was determined by atomic absorption spectrophotometry(AAS).A data matrix of concentration of elements existing in the hair from that here three nationalities is evaluated comprehensively by using probability artificial neural network method.The results show that there are considerable differences among these nationalities.Probability artificial neural network model used to classify and pre... |
