摘　　要：本文提出利用多波长量测数据测定二元配合物组成的新方法。首先以线性最小二乘求得各吸收组分吸收系数；继而应用多元线性回归获取各组分平衡浓度并据物料平衡求得配合物组成比及稳定常数。运用单纯形方法对５个体系测定结果进行了检验。The new method for evaluation of composition in metal-ligand coordination compound is proposed. The absorption coefficience of each absorbing species is evaluated by using least squares and the equilibrium concentration is calculated by multiple linear regression. The composition ratio and stable constants are obtained with mass equilibrium and the experimental results are tested by simplex method. The method is applied in determination of composition for five systems with satisfactory results.
