摘　　要：提出活度系数预测的新方法，用纯物质的一些性质参数按三参数溶解度参数法结合ＭＯＳＣＥＤ模型计算的无限稀释活度系数，选合适的单参数方程求得过量自由焓模型的两个参数，对１１７个二元溶液体系的２２２３个组成点的液相活度系数作了预测。与由文献数据相应方程求得的结果相比，平均相对误差约５％。篈 new method had been employed to predict the activity coefficients in isothermal bina-ries，The results predicted with the present method were compared with those obtained from literature data. For 117 binary systems containing non-polar or polar components，2223 pairs of activity coeffi-cient data were predicted and the overall average relative deviation is about 5％.
