摘　　要：对平衡移动法用于逐级配合体系的适用性进行了研究。结果表明，该法不适用于各分级配合物的稳定常数相差很大，以致各级配合物分步生成的逐级配合体系；而适用于各分级配合物同时生成且各级配合物的吸收曲线重叠和存在等摩尔吸光系数波长或吸收曲线完全不重叠的逐级配合体系。The determination of the composition and stability constant of stepwise complex by Thabile eqUilibrium methed was studied. It concluded that the tnethed was not applicable to the system which eachcomplex was formed separately, it was suitable to that which complexes were formed slinultanoouslyand, moreover, complexes formed had the wavelength Of isoahsorphvity or their absorphon curves weresepax'ated completely.
