摘要:
为研究烟叶原料常规化学成分与烟气成分之间的相互关系,运用数理统计方法对两者进行分析。结果表明:(1)烟气成分的形成与烟叶化学成分间的关系较为复杂,简单相关分析表明烟气中总粒相物、烟气烟碱和焦油量与烟叶烟碱、总钾和总氮含量呈显著相关关系,烟气一氧化碳与烟叶烟碱呈显著正相关,与钾含量呈极显著负相关。(2)偏相关分析表明,烟气中总粒相物、烟气烟碱和焦油量仅与烟叶烟碱含量呈显著的相关关系,一氧化碳和抽吸口数主要与总钾含量呈显著的负相关关系。(3)通径分析表明,对总粒相物、烟气烟碱、焦油量的生成起到主要作用的是烟叶烟碱含量,其次是钾含量,总氮则主要是通过烟碱的间接作用产生影响;烟气一氧化碳主要是受总钾含量的影响,而烟碱本身主要是通过钾的间接作用对一氧化碳起到一定的影响;抽吸口数受总糖和总钾的影响较大,还原糖主要是通过总糖的间接作用对抽吸口数造成影响。因此,对烟气成分影响较大的主要是烟碱、总钾,其中抽吸口数受总糖的影响较大。

Abstract:
In this paper, we focused on the relationship between chemical components and smoke constituents in flue-cured tobacco leaf. The relationships were studied by statistics method, partial correlation analysis and path analysis. The conclusions were as follows. (1) The relationships were complicated between chemical components and smoke constituents. The correlation analysis indicated significant relationships between total particulate matter, smoking nicotine, tar yield and leaf nicotine, K+, total nitrogen; there was a significant positive correlation between carbon monoxide in cigarette smoke and leaf nicotine, while a significant negative correlation between carbon monoxide in tobacco smoke and total K+ was founded. (2) The results of partial correlation analysis indicated that there were significant relationships between total particulate matter, smoking nicotine, tar yield and leaf nicotine, and a significant negative correlation between carbon monoxide in cigarette smoke, puff number and total K+. (3) The path analysis demonstrated that the yield of total particulate matter, smoking nicotine and tar were affected mainly by leaf nicotine, then by total K+, and they were affected by total nitrogen from leaf nicotine indirectly; the yield of carbon monoxide in cigarette smoke was influenced by K+, and by leaf nicotine through K+ indirectly; the puff number was affected by total sugar and total K+, meanwhile by reducing sugar through total sugar indirectly. The yields of smoke components were affected by leaf nicotine and total K+, and puff number was strongly affected by total sugar included.
