提出了柯克伍德-巴夫解理论部分的另一种推导方法，它基本上使用了经典的热力学概念。该理论将溶液的热力学性质与存在的各种分子对的径向分布函数的积分联系起来。对电解质溶液、二组分溶液和三组分溶液导出了有用的表达式。特别重要的是中性电解质的主介质效应的一般表达式和三组分体系中一组分对另一组分溶解度的影响的一般表达式，这表明该理论可以作为讨论水性和相关现象的一般基础。
An alternative derivation of part of the Kirkwood-Buff theory of solutions, which uses essentially classical thermodynamic concepts is presented. This theory relates the thermodynamic properties of a solution to the integrals of the radial distribution functions of the various molecular pairs present. Useful expressions are derived for electrolyte solutions and for solutions of two and three components. Of particular importance are the general expression for the primary medium effect for a neutral electrolyte and the expression for the effect of one component on the solubility of another in a three component system, which shows how the theory can be used as a general basis for discussing hydrotropy and related phenomena.
