应用连续热力学方法，对实验测定的甲乙酮－蜡、苯－蜡、甲苯－蜡、丙酮－调合油、甲乙酮－调合油、苯－调合油、甲苯－调合油７个系统在常压下的汽液平衡数据进行了关联。将连续组分的密度分布函数Ｆ（Ｉ）分别用Γ函数和样条函数，并假定连续组分（油或蜡）间的相互作用参数、离散组分（溶剂）与连续组分之间的相互作用参数为常数，取得了满意的结果。并将该法与虚拟组分法进行比较，结果表明，连续热力学方法具有计算准确度高，计算效率高的优点，是一种值得推荐的好方法。
Seven systems of methyl ethyl ketone - wax, benzene - wax, toluene - wax, acetone - blending oil, methyl ethyl ketone - blending oil, benzene - blending oil and toluene - blending oil were measured by the method of continuous thermodynamics at atmospheric pressure The vapor-liquid equilibrium data is correlated. The density distribution function F (I) of the continuous components is respectively given by the Γ function and the spline function, and the interaction parameters between the continuous components (oil or wax), the interaction between the discrete components (solvent) and the continuous components The interaction parameters are constant, and satisfactory results have been obtained. The results show that the continuous thermodynamic method has the advantages of high computational accuracy and high computational efficiency, which is a good method to recommend.
