| 摘 要： | 用ｘ射线荧光分析法（ＸＲＦ）测定了３０例成绩优良的学生头发中微量元素的含量，并与３０例成绩一般者相比。结果表明，成绩优良者头发中Ｚｎ含量显著高于成绩一般者的含量；两组中Ｃｕ、Ｐｂ的含量也有不同程度的差别。这说明Ｚｎ、Ｃｕ、Ｐｂ元素对神经系统的发育有一定的影响，这结果与现代医学理论相一致。微量元素的研究在教育学上也有一定的意义。

| Abstract: | Information on the contents of Zn. Cu and Pb in hair from 60 students is given. The contents of trace elements were measured by XRF. The results of analyses show that there are more contents of Zn in hair of excellent students than general students. The contents of Cu and Pb in hair also were differential. The difference have an influence on the nervous system. The analysis results were consistent with the theory of moden medical science. The study of trace elements were significant on the teach. |
