中文摘要:

      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价，结果表明认为该体系形成有限固溶体较为合理。

英文摘要:

      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
