摘　　要：本文用电动势法测定了五个温度下总离子强度I恒定为0.2、0.4、0.6、0.8、1.0mol·Kg-1时的ZnCl2-C2H5OH-H2O体系中ZnCl2的离子平均活度系数.实验结果表明,在温度10,15,20,25,30℃时ZnCl2的离子平均活度系数能较好地符合Harnecl规则.The paper determines the activity coefficient of ZnC12 within ZnCl2-C2H5OH-H2O system with the EMF methed under five temperature ranges and gross ionic strength I identified with 0.2,0.4,0.6,0.8 and 1.0mol·Kg^-1 respectively.The result of the experiments shows that the activity coefficient of ZnCl2 is in accord with Harneel rule at temperature of 10.15,20.25 and 30 degree.
