摘要
用三次样条函数描述石油馏分实沸点蒸馏曲线，将连续热力学方法引入石油馏分饱和蒸气压的AP计算式，其结果经大庆、胜利和新疆等原油馏分饱和蒸气压试验数据的检验，优于经典的虚拟组分法。
On the basis of the true boiling point curve described by the cubic spline function, the continuous thermodynamics method was applied to the AN correlation of the vapor pressure calculation for petroleum fractions.The continuous thermodynamics method was investigaed by 430 data points of the vapor pressure of the fractious from three domestic crudes, giving better results than those from the oonverltional pseudocompolents method.
