摘要/Abstract

摘要：应用遗传算法推算溶液热力学数据，并对标准遗传算法作了适当的改进，得到改进的遗传算法.举水+DMF (二甲基甲酰胺)，正丙醇+DMF，水+正丙醇体系推算水+DMF+正丙醇三元体系为例，并与POWELL法比较.计算结果表明，遗传算法比POWELL法不仅在二元参数关联上有更强的能力，而且对预测三元数据也有更好的效果.

Abstract: Genetic algorithm was used to estimate the parameters of thermodynamic model of solution,and a modified genetic algorithm was proposed by modifying the strategy of mutation and the mode of competition.DMF+water+1-propanol VLE system was taken as an example,and the results were compared with those of PWELL method.It is found that the optimization ability of genetic algorithm is much more powerful than that of POWELL method not only in binary composition system but also trinary composition system.

Key words: Modified genetic algorithm, thermodynamic model of solution, parameter estimation
