中文摘要:

      应用电导法测定了NaCl在混合溶剂（1，2-丙二醇和水）中的活度系数，讨论了电解质溶液活度系数与浓度的关系，并计算了NaCl在混合溶剂中的相对偏摩尔自由能，对其相对偏摩尔性质的某些变化规律作了初步的讨论。

英文摘要:

      The activity coefficient of NaCl in mixed solution of water and 1,2-propanediol were measured using conductivity method, and the relationship between activity coefficient and concentration of mixed solution were discussed. The relative partial molar free energy of NaCl in mixed solution were calculated and change law of relative partial molar properties were discussed preliminarily.
