【摘要】 采用回归分析的方法研究了纸通风率对卷烟理化特性的影响规律.结果表明,在实验范围内,纸通风率与烟支吸阻、滤嘴通风率、卷烟主流烟气常规指标、一氧化碳/焦油质量比、3,4-苯并[a]芘含量、烟草特有亚硝胺中的N-亚硝基去甲烟碱(NNN)含量都存在明显负相关性,并可拟合得到对应的回归方程;卷烟感官质量总体评价认为,纸通风率为5%～8%时,卷烟感官质量有所改善.更多还原

【Abstract】 Effects of degree of paper ventilation on cigarette physical and chemical properties were studied by regression analysis.Results indicated that there was negative correlation between the degree of paper ventilation and the investigated cigarette properties including draw resistance,degree of filter ventilation,the MSS conventional components,CO/Tar value,the content of B[a]P & TSNAs in cigarette smoke.Certain regression equation and fitted curves were also constructed.When the degree of paper ventilation was in the range of 5% ～ 8%,sensory quality of the cigarette smoke can be slightly improved.更多还原
