摘　　要：本文应用DSC法评价了几种基础油及其添加剂的热氧化安定性,考察了单一添加剂和复合添加剂对基础油热氧化安定性的影响。实验结果表明,DSC是一种快速简便评价基础油及其添加剂热氧化安定性的方法,并可以用来选定添加剂的最佳浓度及研究添加剂之间相互作用对基础油热氧化安定性的影响。DSC was used to evaluate the thermal oxidation stability of base stocks and their additives. The effects of single additive and composite additives on the thermal oxidation stability of base stocks were investigated. The results indicate that DSC is a rapid and convenient tool to study thermal oxidation stability of lubricating oils. It can also be used to determine the optimum dosage of additives and to study the effect of the interaction between additives on the thermal oxidation stability of base stocks.
