基于TTG理论和Pitzer理论 ,对Ca2 + ,Na+ ∥Cl-,SO42 --H2 O四元相平衡体系 35℃部分相区的密度进行了估算 ,并绘制了密度与溶液浓度关系图 ,估算结果与文献实验数据能较好吻合
Based on TTG theory and Pitzer theory, the density of partial phase region of the quaternary system of Ca2 +, Na + ∥Cl- and SO42 - H20 at 35 ℃ was estimated and the relationship between density and solution concentration was drawn. Literature experimental data can better fit
