摘　　要：电解质溶液中粒子并非简单的共存,体系中一般存在水化与缔合作用,溶液结构与性质通常与理想溶液存在差异比较复杂。为了解释复杂的溶液结构现象,分别采用Stokes-Robinson水化理论、BET模型水化理论、Debye-Hückel离子互吸理论、Bjerrum离子缔合理论和Pitzer电解质溶液理论阐述了离子的水化与缔合作用的存在原理及其发展简史,并通过举例实际数据证明在浓度较高的电解质溶液中离子水化与缔合作用的存在。The coexistence of particles in electrolyte solutions was not simple,and there were generally hydration and association interactions in the system.The structure and properties of the solution were often complex and differ from ideal solutions.In order to explain the complex phenomenon of solution structure,Stokes Robinson hydration theory,BET model hydration theory,Debye Hückel ion mutual attraction theory,Bjerrum ion association theory,and Pitzer electrolyte solution theory were used to explain the existence principle and development history of ion hydration and association.The existence of ion hydration and association in electrolyte solutions with higher concentrations was demonstrated through practical data examples.
