摘　　要：采用偏最小二乘法 (PLS) ,对一价金属卤化物同阴离子二元系固溶体形成规律进行了研究 ,根据研究结果预报表明NaBr-RbBr系可能形成固溶体。并采用差热分析法和目测法重新测定了NaBr-RbBr熔盐体系相图 ,对实验结果进行了热力学评估 。The data of known phase diagrams of molten salt systems of halides of univalent elements have been processed by atomic parameter-pattern recognition method(PLS method) It is found that the solid solution formers and solid solution nonformers are distributed in different regions in a hyperspace spanned by ionic radii and Bansanov's electronegativities of constituent elements Based on the criterion found,NaBr-RbBr system is predicted as a solid solution former And this has been confirmed by our experimental results Based on these results,the thermodynamic evaluation of NaBr-RbBr system have been performed
