烟叶化学成分-品质综合评价物元模型的建立与应用

Establishment and Application of Matter Element Model for Comprehensive Evaluation of Tobacco Quality by Its Chemical Components

简要介绍了物元分析评价模型。为了根据化学成分综合评价烟叶的品质,将烟叶品质的评价等级、化学成分、品质指标作为物元,通过对评价级别和实测数据归一化,得到模型的经典域、节域、权系数及关联度,建立了烟叶化学成分-品质综合评价的物元模型,并用该模型对烤烟和白肋烟化学成分-品质进行了综合评价。结果表明,该模型适合于对烟叶样品的化学成分-品质进行综合评价。该方法算法简单易行,是一种较为简单的烟叶化学品质综合评价方法。

The conception of matter element evaluation model was briefly introduced. In order to evaluate the quality of tobacco leaf by its chemical composition, the quality grade, quality index and chemical compositions of tobacco leaf were used as matter elements, the evaluated grades and tested data were normalized to obtain the sutra field, controlled field, weighting coefficient, and degree of correlation, and establish the matter element model. The quality of several Virginia tobacco and burley tobacco samples was evaluated with the model. It was found that the model was a suitable and simple method for comprehensive evaluation of tobacco quality by its chemical composition.
