对７９４名０～７岁汉族、苗族、布依族学前儿童进行了发中Ｚｎ、Ｃｕ、Ｆｅ元素含量及其相关分析。采用火焰原子吸收光谱仪ＡＡ－６４０－Ｂ型（日本产），数据由ＢＡＳＩＣ语言－多元线性回归（矩阵）处理，结果表明，三种元素分别与年龄、身高、体重存在相关关系（Ｐ＜０．０１）。
The contents of Zn, Cu and Fe in 794 pre-school children aged 0-7 years from Han, Miao and Buyi ethnic groups were analyzed. The data were analyzed by flame atomic absorption spectrometry AA-640-B (Japan) and the data were analyzed by BASIC-Multivariate linear regression (matrix). The results showed that the three elements were related to age, height and weight. 01).
