应用Ｘ射线多道能谱分析仪，检测了１２４７例男女儿童发中７种微量元素的含量，并作了统计分析。经对各种元素含量的分布进行检验，均不服从正态分布。报道了它们的正常值范围，与文献资料报道的基本一致。另外，还对男女儿童发中微量元素含量的差异作了显著性检验。 Using X-ray multi-channel energy spectrum analyzer, the content of 7 trace elements in 1247 male and female children’s hair was detected and analyzed statistically. After the distribution of various elements of the test, are not subject to normal distribution. Reported their normal range, and reported in the literature is basically the same. In addition, significant differences have also been found between the contents of trace elements in boys and girls.
