摘　　要：针对石油馏分质量平均、实分子平均、立方平均和中平均沸点的校正问题进行了研究 ,提出了新的计算数学关联式 ,并进行了参数估计和误差分析。结果表明 :新数学关联式的计算结果与石油馏分沸点曲线给出的数值吻合较好 ,计算准确度较高 ,尤其适用于在线优化计算。New and reliable empirical correlations for predicting the average boiling points of petroleum fractions,which include mass average boiling point, molar average boiling point, cubic average boiling point and mid-average boiling point,were proposed and the deviation was analyzed. It was showed that the results calculated by the new mathematic correlations coincided well with those obtained from the boiling point curve of petroleum fractions.The new mathematic correlations are especially applicable to on-line caluation optimization.
