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 。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.
