摘要
以多环芳烃作为变量,建立了原油、燃料油属性鉴别的费谢尔判别法。分别测定了来自不同国家和地区的26个原油样品和25个燃料油样品中8种多环芳烃的含量,并将它们作为判别变量。借助SPSS 16.0进行费谢尔判别分析,建立费谢尔判别函数。将未知样品的判别变量值代入后,可以快速地得知样品的类别。结果表明,以多环芳烃作为判别变量进行原油、燃料油费谢尔判别快速而准确。
Fisher discrimination of crude oil and fuel oil with polycyclic aromatic hydrocarbons（PAHs）as variables was built.8 kinds of PAHs in 26 crude oil samples and 25 fuel oil samples from different countries and regions were detected, which were used as discriminant variables. By running the SPSS 16.0 software, classification function coefficients were gotten and the Fisher discrimination function was built. The discrimination variables value of unknown species of oil was plugged into the function to quickly identify which class the sample belonging to.As a result, Fisher species identification of crude oil and fuel oil with PAHs as discriminant variables is quick and accurate.
