摘　　要：以不同生产工艺的润滑油基础油作为研究对象,通过对比不同润滑油基础油的动力黏度-温度变化曲线,比较了不同类型润滑油基础油的低温性能,并对其低温性能与组成之间关系及不同类型基础油对降凝剂的感受性差异进行了研究,结果表明,对于同一粘度级别的润滑油基础油,加氢异构基础油低温性能相对较好,而溶剂精制类基础油则对降凝剂表现出更好的感受性。The low temperature performances of lube base oils produced by different processing technologies were tested by the comparison of the dynamic viscosity - temperature curves. The relationship between the low temperature perform- ance and the chemical composition of base oil, and the base oil＇s sensitiveness to pour point depressant were studied in this paper. Research results showed that, the low temperature performance of hydroisomerized base oils is better among all the base oils which are in the same viscosity grade. And solvent - refined base oils are more sensitive to pour point depressant.
