摘　　要：对30#机械油与4106#和4109#航空润滑油进行了加速老化试验;在此基础上,运用阿累尼乌斯方程和性能变化的时温关系式,采用线性回归方法推导出30#机械油粘度变化的老化动力学方程,以粘度增加率20％为使用极限值,预测它在25℃条件下的贮存年限为12 a。该方法可用于其它润滑油的贮存及使用寿命的预测。The oxidation stability of lubricating oils including 30^# machinery oil, 4106^# and 4109^# aircraft lubricating oils was studied out by accelerated ageing test. According to the property-aging time relation and Arrhenius formulation, the ageing dynamic equation of variance ratios of viscosity of 30^# machinery oil was obtained by linear regression method. If the invalidation criterion was selected as P=20%, the shelf-life of 30^# machinery oil was forecasted as 12 years at 25 ℃. The method can be used for forecasting the shelf-life of many lubricating oils.
