用微扰理论及平均球近似关联电解质水溶液的密度

CORRELATION OF DENSITIES FOR ELECTROLYTE AQUEOUS SYSTEMS BY PERTURBATION THEORY AND MEAN SPHERICAL APPROXIMATION

将微扰理论和平均球近似相结合，对纯溶剂采用软球直径和色散能参数（σ和ε／ｋ）两个可调参数，对电解质仅采用阳离子软球直径（σ＋）作为唯一的可调参数，将３６种纯极性溶剂和４０种强电解质水溶液的密度进行了关联，结果较为满意．

Correlation of densities for electrolyte aqueous systems is developed by use of the mean spherical approximation (MSA) and the perturbation theory For pure polar solvents only two adjusting parameters ( σ and ε/k) are needed and for electrolyte aqueous systems only the soft diameters of cations (σ+) are treated as the adjustable parameters The densities of 36 pure polar solvents and 40 electrolyte aqueous systems are correlated The correlation accuracy is satisfactory 
