摘要
本文考虑电解质在混合溶剂中的情况，采用非优先溶剂化观点，并注意到与γ±的关系，通过数学处理．建立了一个两参数（α°、ｈ）的活度系数公式．该式保留了ＳｔｏｋｅｓａｎｄＲｏｂｉｎｓｏｎ活度系数公式的优点，但不包含，且既可适用于单一溶剂体系，又可适用于混合溶剂体系．经对文献２２个体系的处理．表明新建止的公式具有良好的计算精度．所处理的２２个体系的年均相对偏差均小于１％．
Abstract In this paper a new formula of activity coemcicnt of electrolytes has been proposed in termsof Stokes and Robinson Theory (1948). The new formula has all of the advantages of Stokesand Robinson formula (1948), but does not contain osmotic coemcicnt(9). Futhermore, the newformula is applicable to single--solvent and mixed--solvent electrolyte systems. The achvitycoefficients of 22 electrolyte -- containing systems are calculated by the new formula. The resultshave shown good accuracy. The mean or relative deviation of every processed system is less than1%.
