摘　　要：选用几种加氢异构化的基础油作为试验原料,采用核磁共振波谱法分析其烃类结构组成;利用加压差示扫描量热法(PDSC)研究基础油的异构化程度与氧化安定性的关系,考察异构化基础油对抗氧剂的感受性。结果表明,异构化程度高的基础油氧化安定性较好,对抗氧剂的感受性也较好。Several kind of isomerizated hydrogenation base stocks were selected as the material, and their structure and composition were analyzed by NMR. The relationship between isomerization ratio and oxidation stability were investigated by pressure differential scanning calorimetry （PDSC）, and impressibility of the base stocks for antioxidant were also stud- ied. The results show that the higher isomerization ratio in base stock possesses better oxidation stability and better antioxi-dant sensibility.
