【摘要】 从偏心因子(acentricfactor)的定义出发,分析了ω数据的确定方法和获取数据的手段,评述了国内外ω计算方法的近期进展,包括对应态蒸气压关联方程法、对应态基团贡献法(CSGC)、图论法及拓扑法等,指出了各种方法的优缺点及最新的计算发展方向。更多还原

【Abstract】 The paper analyses the methods of determination and acquire of acentric factor(ω)data, basing on the definition of acentric factor. The recent research progress of the calculating method of acentric factor was reviewed, including vapor pressure equation of corresponding state method, corresponding state group contribution (CSGC) method, Graph Theory and Molecular Topology Method, and their advantages and disadvantages, as well as the latest trend were also discussed.更多还原
