| 摘 要： | 灰色关联分析是灰色理论中的一种分析方法，这种方法的基本思想是根据所研究的因子间变化的相似程度来判断关联程度。应用关联分析的这一原理，通过各种内在质量对综合评分的关联系数(k)及关联度r，研究影响综合评分的主要内在质量的影响程度，分析了烟草内在质量与综合评分之间的关联度，结果表明烟草主要内在质量与综合评分之间的关联度依次为糖碱比>糖差>总糖>还原糖>氮碱比>K2O% >总氮>蛋白质>烟碱，为云南优质烤烟质量标准体系建立提供一种简捷、科学的理论分析方法。

| Abstract: | Grey incidence analysis is an analytical tool based on grey theory. The basic ideology is to estimate the relation of factors studied by the change of their similarity. According to this theory, through the relation index (k) and relation R, to study the degree of incidence, we analyzed the incidence between the integral rating and the inner quality of tobacco. The results indicated that the order of relational grades of main qualitative characters is the ratio of sugar and nicotine>total sugar>reductive sugar>the ratio of nitrogen and nicotine>K2O%>total nitrogen>protein>nicotine. The results will provide theoretical base to the design of the standard quality system of Yunnan Tobacco. |
