2、丝掺配样品”较“传统梗丝掺配样品”的抽吸口数增加0.18El/支,焦油量降低0.867mS/支,烟碱量降低0.055ms/支,一氧化碳降低0.726ms/支;②接装纸不通风时,随梗丝掺配比例增加,传统梗丝掺配样品的抽吸13数有成比例降低趋势,而微波梗丝掺配样品的抽吸口数基本保持在7.7H/支不变;③较传统梗丝掺配样品,试验条件下6组微波膨胀梗丝掺配样品的吸阻均值高51Pa;④微波膨胀梗丝的自由燃烧速率略低于传统梗丝,分别为11.51mm·rain~、12.04mm·rain~;⑤微波膨胀梗丝降低焦油、一氧化碳的效果均优于传统梗丝,焦油、一氧化碳释放量均值分别降
3、低0.4mg/支、1.0ms/支,降低烟碱的效果略低于传统梗丝。关键词:微波膨胀梗丝;传统梗丝;主流烟气;抽吸口数;焦油;烟碱;一氧化碳中图分类号:0659.3文献标志码:AResearchontheinfluenceofmicrowaveexpandedcutstemonthereleaseoftheregularcomponentsinmainstreamcigarettesmokeZOUQuan,LIAOXiao—xiang,WUKai,ZHAOYun—chuan,CHENRan,DUANLi—yue,ZHAOJuan,LIXin,WEIHong,XUW
