摘　　要：针对实时仿真等工作对快速运行的苛刻要求,通过对石油馏分焓值图表的拟合,提出了可用于常压石油馏分焓值计算的简化数学关联式,并进行了参数估计和误差分析。通过实例应用表明:该式计算速度快与焓值图表吻合较好。In order to speed up the execution of real- time simulation, new and reliable empirical correlations for gas enthalpy and liquid enthalpy are proposed by fitting enthalpy of petroleum fractions, which can be applied to computer calculation, and then carrying on estimation of parameter and error analysis. Two correlations have been tested respectively by an example, and show fine accuracy as compared with data of enthalpy figures of petroleum fractions.
