镨钕分离系数与组成关系的数学模型

Mathematical Model of Separation Coefficient Between Pr and Nd with Regard to the Solution Composition

对生产实际中采集的数据 ,用回归分析的方法 ,建立了 4组分 2出口体系镨钕分离系数与组成关系的数学模型 ,并应用到动态模拟程序中 ,模拟结果与实际采样分析结果非常接近 ,证明了模型的正确性 .

Based on the data from production and practice, a mathematical model for the dependence of separation coefficient between Pr and Nd in four componentstwo outlets system on the solution composition has been built and used in computer simulation program. The simulation results are identical with actual cascade distribution, which proves that the model is correct.
