运用集对分析法评价烟叶化学成分协调性

Using set pair analysis to evaluate harmonic character of tobacco chemical components

根据集对分析原理,评价了UV-B辐射试验中12个烟叶样品化学成分的协调性,并将评价结果与指数和法的评价结果进行了比较。结果表明,通海大田的烟叶化学成分协调性最好,其余样品评价等级均较低。UV-B辐射强度低于自然环境处理的烟叶化学成分协调性较差,这说明减弱UV-B辐射对烟叶品质不利。评价实例说明两种方法的评价结果一致,但集对分析法结果更为直观。

The harmonic character of tobacco chemical components was evaluated based on set pair analysis （SPA） and compared with that tobacco leaves from Tonghai are the most harmonious. Leaves of 12 samples collected from ultraviolet B radiation outcome of integrated index method. Results showed with less ultraviolet B radiation intensity than their natural counterparts showed less harmony. It was found that ultraviolet B radiation had a positive effect on tobacco leaf quality. Two methods showed similar results with SPA method more intuitive.
