摘　　要：分析了市售柴油、机油、煤油、汽油及混合油水溶液的激发光和荧光光谱,研究了它们的光谱特性.在优化选择激发光波长和荧光波长下,对不同浓度的矿物油水混合液进行了荧光光谱分析,得到了荧光光谱强度与浓度的关系,并对实际环境的水样进行了测量分析.Excitation spectrum and fluorescence spectrum of diesel oil, machine oil, coal oil, gasoline and their mixture in aqueous solution were measured and characterized. The relations of intensity and concentration were obtained by measuring fluorescence spectrum of different concentration mineral oil in water at a certain excitation wavelengh. The difference of fluorescence wavelength and intensity at some excitation wavelength were explained, and the sample of actual water were also measured.
