对11个不同基础油含量的50-1-4Ф润滑油样品（标准油）和从现场采集的28个在用50-1-4Φ润滑油样品（在用油）进行傅立叶变换中红外光谱分析。选择1465 cm-1作为测定其运动粘度的特征峰，分别对标准油和在用油样品的运动粘度和相应红外光谱的特征峰处的吸光度进行了相关性分析，给出了回归方程。用另外20个新油样品较正了标准油的回归方程。结果表明，利用傅立叶变换中红外光谱法测定未用及在用50-1-4Φ润滑油的运动粘度是可行的，测定结果是可靠的。

This paper analyzed 11 lubricating oil 50-1-4Φsamples of different base oil content (standar d oil) and 28 used oil samples by Fourier transform mid-infrared spectrometer (FTIR) .First ,the absorption peak of 1 465 cm-1 was selected as the characteristic peak for determining their kinematic viscosities .And then correlation of the kinematic viscosity and the absorbance at characteristic peaks of corresponding infrared spectrum of standard oil and used oil samples was analyzed ,re-spectively ,and two regression equations were proposed . Finally , the regression equation of standard oil was corrected through other 20 new oil samples .The results show that determining kinematic viscosity of new lubricating oil 50-1-4Φ and the used one by FTIR is feasible and reliable .
