| 摘 要： | 选取了光测法检测油液污染度，在适合的波段内，油样对光均具有一般吸收，透光率相对稳定且较大；油样粘度的变化对透光率影响较小，而油液颜色的深浅对透光率有影响。导出了定量分析油液污染程度、消除油液颜色影响和提高检测精确度的理论公式，讨论了影响检测结果的因素及相应的解决方法．

| Abstract: | On the basis of theory of light and lots of experiments, the proper light wavelength is determined. In the wave band, oil samples imbibe light with general absorp tion, intensity of penetrating light is more stable and higher relatively, variations of oil viscosity have little effect upon ratio of penetrating light,and change of oil color influ- ences ratio of penetrating light.With the Lambert-Beer law combined with the system of single source and double laser-lights, theoretic foundation is inferred for quantitative analy- sis of oil contamination, eliminating influence of oil color and improving accuracy of the device. |
