| 摘 要： | 提出一种利用原油宽馏分数据，预测任何温度范围的馏分油收率和物理性质的方法。首先推导了馏分油性质与馏程起、止温度的二元关系式，然后对馏分油各种性质确定了预测策略，即整体拟合还是局部插植。经过对数百种原油的广泛检验，证明提出的预测方法是适用的。

| Abstract: | A method for the prediction of distillate yield and physical properties in whatever distillationtemperature range, basing on known data of wide boiling fraction from crude, was proposed. First, a dual polynomialcorrelating the distillate properties with the fraction TBP range was derived. Secondly, the prediction strategies, i. e,wholly curve-fitting or locally interpolation, were detendned to different crude fraction properties. Throughexathenation on hundreds of crudes, a satisfactory accuracy of this prediction method was proved. |
