电解质 NRTL模型是重要的热力学局部组成模型。本文阐述了电解质 NRTL 模型的研究进展过程，包括模型的提出、修正、改进和扩展，同时指出了不同模型的适用范围。介绍了模型在各种复杂电解质溶液体系关联计算中的应用，可以为一些工业生产过程的模拟、设计和优化提供理论指导。电解质 NRTL 模型的主要优势是适用的温度和浓度范围宽，不需二元以上高阶参数；但模型自身也存在缺陷，如参数的回归工作量大、在溶液体系临界点处的预测精度较差等，故模型仍需进一步完善。

The electrolyte NRTL model is a kind of important thermodynamic local composition model. This paper describes the research progress of the electrolyte NRTL model,including proposition, improvement,modification and extension of the model and the scope of application of different models. Some applications for correlation calculation of various kinds of complex electrolyte solutions are introduced,providing theoretical directions for process simulation,design and optimization. The main advantage of the electrolyte NRTL model is that it is applicable to a wide range of temperature and concentration with no need for high-order parameters. The disadvantages of the model are heavy regression work for parameters,and poor prediction accuracy at the critical point of electrolyte solution.
