【摘要】：将相似度计算法引入到汽油的溢油识别中,将油品的谱图信息转化为二维向量,利用夹角余弦法计算二维向量间的相似度,并以此来表征谱图之间的相似度。对2个组成相似的催化裂化汽油进行了模拟溢油识别。结果表明,催化裂化汽油萃取油E-1与样品油C-1、C-2的相似度分别为0.996、0.974,前者大于后者,萃取油E-2与样品油C-1、C-2的相似度分别为0.983、0.992,前者小于后者,2个萃取油与对应原样品油的相似度结果均高于其与另外一个样品的相似度。在重复性限法和t检验法均无法完全识别的情况下,利用相似度计算法可以准确找到萃取油对应的原样品油,解决了相似油品识别、汽油识别的难题。
[Abstract]:The similarity calculation method is introduced into the oil spill recognition of gasoline. The spectrum information of oil products is transformed into two dimensional vectors, and the similarity between the two dimensional vectors is calculated by means of the angle cosine method, and the similarity between the spectra is represented by this method.Two FCC gasoline with similar composition were identified by simulated oil spill.The results showed that the similarity between E-1 and C-1C-2 was 0.996N 0.974, the former was higher than the latter.The similarity between the extraction oil E-2 and the sample oil C-1C ~ (-2) was 0.983n 0.992, the former was smaller than the latter, and the similarity between the two oil and the sample oil was higher than that of the other sample.Under the condition that the repeatability limit method and t-test method can not be fully recognized, the original sample oil corresponding to the extracted oil can be accurately found by using similarity calculation method, and the problem of similar oil identification and gasoline recognition can be solved.
