卷烟烟气指标与烟丝化学成分的相关性

Correlation Between Smoke Indexes of Cigarette and Chemical Components of Cut Tobacco

为探明卷烟烟气指标与烟丝化学成分的相关性,采用灰色关联分析方法,研究了卷烟烟气指标与烟丝化学成分之间的关联度。结果表明:焦油关联度总糖最高,达0.80,各指标大小依次为总糖>还原糖>糖碱比>总氮=总烟碱>氮碱比>钾氯比>钾>氯;烟碱关联度总烟碱最高,达0.78,各指标大小依次为总烟碱>总糖=还原糖>总氮>糖碱比>钾氯比>氮碱比>钾>氯;CO关联度总氮最高,达0.71,各指标大小依次为总氮>钾氯比>总烟碱>氮碱比>糖碱比=总糖>钾>还原糖>氯。

The relational degree between smoke index of cigarette and chemical components of cut tobacco was determined by the grey correlation analysis.The relational degree between tar and total sugar was up to 0.80 （the highest）and the relational degree between tar of cigarette and chemical components of cut tobacco was total sugar〉reducing sugar〉sugar-nicotine ratio〉total nitrogen=total nicotine〉nitrogen-nicotine ratio〉K-Chl ratio〉K〉Chl The relational degree between cigarette’s nicotine content and total nicotine content of cut tobacco reached 0.78 and the relational degree between cigarette’s nicotine content and chemical components of cut tobacco was total nicotine〉total sugar=reducing sugar〉total nitrogen〉sugar-nicotine ratio〉K-Chl ratio〉nitrogen-nicotine ratio〉K〉Chl.The relational degree between cigarette’s CO content and total nitrogen content of cut tobacco was 0.71 and the relational degree between cigarette’s CO content and chemical components of cut tobacco was total nitrogen〉K-Chl ratio〉total nicotine〉nitrogen-nicotine ratio〉sugar-nicotine ratio=total sugar〉K〉reducing sugar〉Chl.
