【摘要】 以石蜡基基础油数据为基础，建立了以调合组分的常用理化性质计算调合内燃机油基础油的低温表观粘度的６种数学关联式。用这些关联式预测了５种３组分调合石蜡基基础油的低温表观粘度取得成功。与实测结果相比，使用关联式的平均相对误差在３．６７％～７．１７％。效果最好的平均相对误差为３．６７％，最大误差为５．９３％，能够满足油品开发的需要。更多还原

【Abstract】 six correlation equations were established on the basis of the physico-chemical properties such as viscosity indices and densities of the blending components for calculating the low-temperature apparent viscosity of the blended base oil of internal combustion engine. Several apparent viscosities of the blended base oils were predicted by these equations. In comparasion with the test result, the average relative errors were in the range of 3. 67% to 7. 17%.更多还原
