【摘要】 将电解质溶液的局部组成模型中的粒子间作用能看作常数 ,与温度无关 ,使得模型参数与温度成简单的倒数关系 ,利用 2 5℃的模型参数值 ,关联计算了在不同温度下NaCl KCl H2 O三元体系溶解度数据 ,结果表明在 0～ 1 2 0℃的范围内 ,关联计算结果很好 ,解决了局部组成模型在计算电解质溶液溶解度时缺乏其他温度下模型参数的问题更多还原

【Abstract】 In this paper , it is assumed that the energie s of interaction between species did not vary with temperature and , as a result , the model parameters were inversed with temperature . With the model parameters at 25℃, thesolubilities of NaC1-KC1-H 2O at O ～ 120℃ were correlated and calculated. Th e predicted solubilities agreed well with experimental data. The research had s olved the problem of the absence of the model parameters at various temperature s.更多还原
