摘　　要：本文探讨和论证了平衡移动法中Ａｍａｘ值对测定配合物组成和稳定常数的影响．确定当吸光度值Ａｉ≤０．８Ａｍａｘ时，在一定测量误差范围内的不同Ａｍａｘ值可得到相同的配合物组成，但对稳定常数测定的影响无法消除．用实例对上述结果加以验证。In this paper, the effects of A max on the mobile equilibrium method for the determination of the composition and stability constant of coordination compound were approached and proved. If the absorbances of the coordination compound (A i) were no more than 0.8A max , the same compostion was obtained with different values of A max within a limited range, but its effect on the determination of stability constant was not neglected. The results discussed were proved to be correct in real examples.
