摘    要:海洋溢油是主要环境灾害之一,而且近年来其发生频率呈上升趋势。快速地对油品进行种类鉴别、来源评估有利于及时采取应急措施,因此具有重要意义。采用衰减全反射傅里叶变换红外光谱法(ATR-FTIR)对25种不同来源的油品进行了检测,用不同数据预处理方法对原始光谱进行了预处理,继而用主成分分析(PCA)和系统聚类分析(HCA)方法对光谱进行了分类鉴别。结果表明用多元散射校正(MSC)和连续小波变换(CWT)方法进行数据预处理可以提高分类的准确性,使分类结果与油样的实际来源一致。该方法对正构烷烃差异较大的油品进行了很好的区分,但对差异较小的油品其分辨能力仍有一定局限性。因此提供了一种快速的油品鉴别方法,可用于溢油事件的初步鉴定,从而为油品的进一步鉴定提供有用信息。

关 键 词:油品  分类  衰减全反射傅里叶变换红外光谱  主成分分析  系统聚类分析

Abstract:In the present work,the combination of attenuated total reflectance-Fourier transform infrared spectrometry(ATR-FTIR) and pattern recognition,including principal components analysis(PCA) and hierarchical cluster analysis(HCA),is used as a fast and convenient analytical tool to classify oil samples.Twenty five samples including crude oils and fuel oils with different total contents of n-alkanes were analyzed.It was found that multiplicative scatter correction(MSC) and continuous wavelet transform(CWT) as a p...
