摘　　要：相对色谱或色质联用分析,荧光分析法具有灵敏度高、选择性好、取样量少、分析结果快速等优点。三维荧光光谱是有机物种类鉴别领域的新技术,可应用于石油馏分的分类,且具有准备过程简单、信息量丰富和费用低的优点。分析了柴油、汽油、混合油3类石油馏分的三维荧光光谱特征,应用图像信息统计原理,提出了基于三维荧光等高线特征谱分析技术的一种新方法,研究了同一馏分和不同馏分之间特征谱的相关特性,并给出了利用等高线特征谱相关系数鉴别油品的新方法,对3类馏分的分析结果表明,此方法数据客观,识别结果准确。Compared with chromatography or mass spectrometry analysis, fluorescence analysis has the advantages of high sensitivity, good selectivity, using less sample and rapid analysis speed. Three-dimensional （3D） fluorescence spectroscopy is a new technology in organic species identification field, which can be applied to the classification of petroleum distillates, and has the benefits of simple preparing process, rich information and low cost. This paper studies the 3D fluorescence spectral characteristics of diesel, gasoline and mixture, and proposes a new analysis method based on the characteristic spectrum of 3 D fluorescence contour plot using image information statistical theo- ry. The correlation of the characteristic spectrums for the same distillate and different distillates is studied; and a new method using the correlation coefficient of contour characteristic spectrums to identify petroleum products devel- oped. The analysis results for 3 distillates show that this method can identify different oils with high accuracy.
