摘　　要：在２５±０．１℃，Ｉ＝０．１ｍｏｌ·Ｌ－１ＫＮＯ３条件下，应用ｐＨ法测定了甲酰基甲酸缩氨基硫脲（Ａ配体，缩写Ｈ２ＦＦＴＳＣ），甘氨酰甘氨酸（Ｂ配体，缩写ＨＧＧ）的质子化常数，它们与锰（Ⅱ）、钴（Ⅱ）、镍（Ⅱ）、铜（Ⅱ）和锌（Ⅱ）的二元配合物以及过渡金属（Ⅱ）－甲酰基甲酸缩氨基硫脲－甘氨酰甘氨酸三元配合物稳定常数，讨论了过渡金属席夫碱配合物的杀菌活性与其稳定性之间的关系。=\; The protonation constants of formylformic acid thiosemicarbazone (A, H\-2FFTSC) and glycylglycine (B, HGG) and stability constants of binary complexes formed they with Mn(), Co(), Ni(), Cu() and Zn() and trinary complexes of M()FFTSCGG at 250.1 and in the presence of 0.1 molL\+\{-1\} KNO\-3 were determined. The relation between the stability of binary complexes of M()FFTSC and their disinfectivity and disinfection mechanism were discussed.\=\;Z]
