【摘要】 根据溶液理论分析,通过固液之间的逸度比,将活度系数和溶质、溶剂的热力学性质联系起来,利用热力学性质计算溶解度数值。在理想溶液基础上,采用了可适用于非极性溶质-溶剂系统的正规溶液关系式,对水在液氮中的溶解度进行了计算,并将理想溶液理论的结果与正规溶液理论结果进行了对比。在计算结果的基础上对水在液氮中的存在形式进行了探讨。更多还原

【Abstract】 According to the theoretical analysis of the solution,the activity coefficient is related to the thermodynamic properties of the solute and the solvent by the ratio of the fugacity between the solid and the liquid,and the solubility value is calculated based on the thermodynamic properties. On the basis of the ideal solution,the normal solution relationship that can be applied to the non-polar solute-solvent system was used to calculate the solubility of water in liquid nitrogen,and the result of ideal solution theory was compared with the result of regular solution theory. The existence form of water in liquid nitrogen was discussed based on the calculation results.更多还原
