摘　　要：利用多种国外中间基原油VGO的实验分析数据,采用Origin Pro8数据分析软件经二元回归,建立了50℃运动粘度和100℃运动粘度计算相对分子量的经验关联式,通过该三十三种VGO的相对分子量计算值与实测值对比,预测结果的平均相对误差为4.16%,表明此公式拟合精度较高、预测能力较强,可用于国外中间基原油VGO相对分子量的初步预测。Use of foreign middle base oil VGO experimental analysis of data,using the Origin Pro8 data analysis software,established by the binary regression 50 ℃ motion viscosity and 100 ℃ motion viscosity of calculating the relative molecular weight,through this experience relational VGO 33 kinds of the relative molecular weight compared with the measured values calculated,the average relative error of the predicted results for 4.16 %,showed that the formulas fitting accuracy is higher,forecasting ability strong,can be used for foreign middle base oil VGO relative molecular weight preliminary forecast.
