| Abstract: | Based on the near-infrared spectrograph of 300 samples of tobacco,combining the ratio method and multiple quadric regression method,we build a model which reveals the relationship between the near-infrared spectrograph with the contents of six fractions of tobacco.The model is tested with cross validation and actual measurements,the results show that the model gives good prediction.It offers an efficient method for fast detection of tobacco quality.Since it needs only several measurements,and the calculation is simple and convenient to realized,this method is easy to popularized and commercialized. |
