| Abstract: | The fingerprint of tobacco flavor was established by using GC/MS method.The cosines of included angle,correlation coefficients and extent similarities of 6 batches of samples,diluted samples and mixed samples of 12 tobacco flavors were calculated and compared.The results showed that the extent similarity algorithm could reflect quality difference among samples better. |
