摘　　要：对纯流体及其混合物的普遍化范德华配分函数的推导作系统阐述。由该配分函数可导出一些重要的状态方程、混合规则及活度系数模型。还分析了与密度有关的局部组成模型的低密度边界条件。A derivation of the generalized van der Waals partition finction for pure fluids and mixtures is provided. The results of the derivation can be used as a basis for understanding equation of state, their mixing reles, and activity coefficient models. The low density boundary condition of density dependent local composition thermodynamic models is clarified in this parper, and the theory will be the basis for the following papers in which a new developed density dependent local composition model will be proposed and applied in the fluid phase equilibrium calculations.
