摘要
在Pitzer提出的求解活度系数数学模型的基础上,建立了四元体系液-固相平衡数据的计算方法和计算机程序。计算结果同实验数据比较的结果表明,该方法能用于NaCI-KCl-NaNO_3-KNO_3-H_2O体系相平衡数据的计算。
Based on the mathematic model of activity coefficient made by Pitzer, presents a calculating method and program for liquidsolid phase equilibrium with the 4-components system.The comparition between calculating and experimental results shows that this method is suitable to calculate the phase equilibrium data for NaCl-KCl-NaNO_3-KNO_3-H_2O system.
