用旋转氧弹法和加压差示扫描量热法考察了受阻酚类抗氧剂在基础油中的抗氧化性能。结果表明，大分子量的单酚抗氧剂和双酚结构的抗氧剂具有优异的抗氧化性能；计算所得抗氧剂在基础油中的氧化活化能数据对抗氧剂的应用有借鉴作用。
The antioxidant properties of hindered phenolic antioxidants in the base oil was studied by Rotating Pressure Vessel Oxidation Test and Pressurized Differential Scanning Calorimetry.The results showed that antioxi-dant of a single high molecular weight phenolic and bisphenol structure had excellent anti -oxidants properties.The oxidation activation energy of antioxidants in the base oil had been calculated by Software ,which was helpful in the application of antioxidants.
