摘　　要：基于两种发展趋势综述了Debye-Hckel理论及其相关的理论研究进展。其一是在Debye-Hckel理论基础上添加新参数而引出的如Guggenheim、Bromley等修正模型,或者是考虑了电解质溶液溶剂化和离子缔合等影响而构成的如Stokes-Roberson理论和Bejumm理论等,这些理论(或模型)均只考虑粒子间长程相互作用;其二是考虑了粒子间短程相互作用,并与传统的长程相互作用加和形成如Pitzer、NRTL、CDH和三参数模型等。同时,简要概述了上述理论(或模型)在活度系数、相平衡等方面的应用。The progress of Debye-Huckel theory is reviewed based on two aspects, one is the modified models, such as Guggenheim and Bromley model derived from Debye-Huckel theory by adding some parameters, as well as Stokes-Robinson theory and Bejumm theory by considering of the solvation and ion association of the electrolyte solution. All these theories（or models） are just considering the long-range interactions among particles; the others are the new models such as Pitzer, NRTL, CDH and three parameters models proposed by combinating the short-range interactions and the traditional long-range interactions. Addtionally, the applications of these theories（or models） in activity coefficient, phase equilibrium and other fields are presented.
