对配制的不同3号喷气燃料含量的50-1-4Ф润滑油样品作为航空润滑油燃料污染水平测定的标准模拟油样进行红外光谱分析，选择红外谱图中805~755 cm -1区域作为测定滑油燃料污染水平的定量区域，对此区域峰面积与相应的样品燃料污染水平的相关性进行分析并给出回归方程。结果表明利用傅立叶变换红外光谱法测定航空润滑油的喷气燃料污染水平是可行的，测定结果是可靠的。

A series of lubrication oil 50 - 1 - 4Ф samples with different RP - 3 content were prepared. And then these samples were analyzed by Fourier transform mid - infrared spectrometer (FTIR). The infrared region of 805 ~755 cm - 1 was selected as quantitative area for determining fuel pollution level of aviation lubrication oil. Finally, cor-relation of the peak area and the fuel pollution levels of corresponding samples were analyzed, respectively. And the regression equation was proposed. The results showed that determining jet fuel pollution level of aviation lubricating oil by FTIR was feasible and reliable.
