摘　　要：通过对石油馏分的焦点温度图和焦点压力图的拟合,提出了可用于计算机计算的数学关联式,并进行了参数估计和误差分析。通过应用实例表明:该数学关联式的计算结果与石油馏分焦点温度图和焦点压力图给出的数值吻合较好,计算准确度较高。New and reliable empirical correlations for focal temperature and pressure of petroleum fractions are proposed by fitting the focal temperature and pressure figures of petroleum fractions,which can be applied to computer calculation, and then carry on estimation of parameter and error analysis. Two correlations have been tested respectively by an example, and the result shows good accuracy as compared with data of the focal temperature and pressure figures.
