| 摘 要： | 本文基于分子热力学理论提出了硬球引力场的分子聚集模型。使用该模型从而将简单维里方程改造为分子聚集型维里状态方程，由它可准确计算包括极性物质在内的饱和汽相体积。计算结果表明，本方程的计算精度优于Ｔｓｏｎｏｐｏｕｌｏｓ方法。

| Abstract: | molecular aggregation theory was proposed based on the model of hard--spheremolecules and weak attraction by the statistical mechanics method. Considering molecularaggregation action, the simple Vinal equation was modified into the Vinal equation of statefor molecular aggregation which can precisely calculate saturated vapor volume for mostsubstances including polar ones. The calculated result shows that calculation precision byusing this equation is superior to that of the Tsonopoulos method. |
