摘　　要：本文用常规油品测试方法和傅立叶红外光谱(FTIR)研究了石油地质钻井动力装置MB-820柴油机油在使用过程中的降解规律。润滑油添加剂和油品老化基团的特征红外吸收显示,不同品质的新油在使用中的变化规律差别较大。The conventional oil products testing methods and Fourier Fransform infra- red spectra have been used to study the degradation pattern of the diesel oil during its use in MB-820 diesel engine. The characteristic IR absorption of the aging groups in lubricating oils and additives indicate that the degradation pattern of oil in use varies significantly with the properties of the fresh oil.
