Abstract: The method of calculation of saturated liquid density, based on the Hansons method, has been proved theoretically from Haggenmachers equation of state. A critical compressibility has been used as a parameter for dividing the compounds into groups to overcome the defeat of Hansons method. The error of Saturated liquid density, calculated by this method, was within 1%. In this paper, a method for calculation of Saturated vapor densities and mixture liquid densities and a generalized equation of heat of vapolyzation was also given. These results proved that the theorem of corresponding state, could be applied to two phases region.

摘要： 本文证实了Hanson计算方法的可能性,并应用了跨界压缩因子解决了Hanson方法中存在的缺点.计算饱和液体的密度,其误差在1%以内,本文尚提供了计算饱和蒸气的密度和混合液体的密度的方法.导出了一个计算汽化热的普遍公式.这些结果证明了在两相区域内可以应用对比状态的规律.
