Abstract: Ornstein-Zernike（OZ）integral is solved for unsymmetrical sticky electrolyte solutions with overlap at various distances between ions equal to or less than the collision diameter.Based on the mean-spherical (MSA),all correlation functions and thermodynamic properties can be expressed explicitly in terms of the sticky parameters obtained through a self -consistent procedure.With the reference of an ideal-gas mixture,numerical results of osmotic coefficient and activity coefficient for mixtures with stickiness between oppositely charged ions are presented.

摘要： 在粘性电解质模型（SEM）的基础上，研究了不等直径离子间有缔合作用的电解质溶液，其缔合位置小于或等于硬球的接触直径.求解Omstein-Zemike积分方程时，在核内和核外分别采用超网链近似（HNC）和平均球近似（MSA）作为封闭条件．系统的相关函数和热力学性质均表示为系统状态所决定的特性参数，并给出广泛的数值结果．
