摘要
将Ｒｅｉｓ提出的硬球表面张力模型用于计算纯熔盐和混合熔盐体系的表面张力将硬球直径视为温度的函数，对２３个纯熔盐体系的表面张力进行了关联，得到相应的分子参数，表面张力的关联总体平均偏差为０４８％应用ｖａｎｄｅｒＷａａｌｓ理论－１混合规则，将Ｒｅｉｓ的表面张力模型推广到混合熔盐体系，对２７个二元熔盐混合体系的表面张力进行了预测和关联，总体平均偏差分别为３３８％和１０４％。
The hard sphere model of surface tension proposed by Reiss is extended to calculate the surface tension for pure and binary molten salts The surface tension of 23 pure molten salts are correlated by treating the hard sphere diameter of a molecule in molten salt as a function of temperature with the total average deviation of 0 48% The van der Waals theory-1 mixing rule is introduced into Reiss model for mixture of molten salts The surface tension for 27 binary molten salts is either predicted by taking k ij =0 or correlated by treating k ij as an adjustable parameter The total average deviation is 3 38% and 1 04%,respectively These correlations seem to provide satisfactory prediction of surface tension for industrial application
