摘　　要：采用线性回归及动态吸氧的方法研究了碱性氮和非碱性氮对润滑油基础油氧化性能的影响。线性回归处理结果表明 ,非碱性氮对基础油的氧化性能影响最为显著。动态吸氧的结果表明 ,低氮含量时氮化物促进饱和烃氧化 ,高氮含量时氮化物抑制饱和烃氧化。饱和烃的氧化性能随非碱性氮含量的改变显著大于碱性氮 。The influence of basic- and non-basic-nitrogen compounds on oxidation of saturates was studied with mathematical regression and dynamic oxygen uptake method. The results indicated that nonbasic-nitrogen was the main influence factor to oxidation. The results of dynamic oxygen uptake unveiled the nature of the influence of non-basic-nitrogen compounds on the oxidation of saturates under different catalytic conditions.
