摘　　要：研究了三种有机溶剂、五种有机试剂、八种表面活性及水溶性高分子化合物对生命科学、环境科学上感兴趣的十一种元素Fe、Co、Ni、Mn、Zn、Cu、Cd、Cr、Sr、Pb、Mg等的增敏作用。它们对这些元素都有不同程度的增敏,最大值敏倍数达9.5倍。In this papar, studied the enhancement effect of three organic solvents, five organic reagents, eight surfactants and water-soluble polymers in FAAS for Fe, Co, Ni, Mn, Zn, Cu, Cd, Cr, Sr, Pb and Mg, which are interesting elements in the environment science and the life science. The results indicated that the degree of enhancement is different for every element. The maximum enhancement ratio is 9.5 times. The auther also investigated the enhancement effect and their mechanism of some three or four molecular assembles.
