摘　　要：按Ｓｉｇｅｌ建议的方法，用作图外推结合单点计算法，求出钙（Ⅱ）与丙二酸、氨基乙酸形成三元混配化合物，测出其Ｃａ（Ⅱ）丙二酸氨基乙酸＝１１１组成的稳定常数β１１＝２．１２×１０５，可能形成较为稳定的配合物．Basing on the sigel method, a mixed complex is theoretically found which is formed by Ca(Ⅱ) with Glycine and malonic asid.The stability constant of the complex, in which Ca(Ⅱ)∶malonic acid∶glycine=1∶1∶1,is determined to be β 11 =2.12×10 5,which implies that the complex may be a stabler one.
