| 摘 要： | 基于ASTM D2887与ASTM D86测试标准的馏程关联方法是气相色谱模拟蒸馏工程应用的一个重要技术研究方向，关联模型的泛化能力和鲁棒性是评价模型性能的主要指标。根据色谱模拟蒸馏技术的恩氏蒸馏馏程测定方法，以ASTM方法模型为基础，利用模型计算值与实验值之间的误差获得模型校正参数，对原始模型进行校正，提出了基于加权优化均方差及方差的关联建模方法。通过理论分析、数学计算及工程应用，验证该方法具有很好的鲁棒性和泛化性。工程应用结果表明：提出的色谱模拟蒸馏与恩氏蒸馏数据的关联方法，不仅能扩展模拟蒸馏的使用范围，而且为快速测定油品馏程提供一种可靠的分析手段。

| Abstract: | The test criteria of ASTM D2887 and ASTM D86 for distillation range is one of the important research area in gas chromatography.For correlation modeling the generalization and robustness is also the major target to evaluate.In this paper a modeling method based on the weighted mean-square deviation and variance optimization is proposed.This method is used in Engler boiling range distribution measurement which usually calculated by ASTM means,to calibrate the coefficients of the original model by the value errors between the model prediction and laboratory analysis.Theory study，mathematical calculation and technology application verified the robustness and generalization property of this method.The application results indicated that the correlation modeling method of the chromatography distillation range and Engler boiling range can be used to the application of simulation distillation and a reliable analysis means for quickly measuring the oil distillation range. |
