摘　　要：为揭示电加热卷烟温度分布和关键成分逐口释放规律,分析测试了不同抽吸模式下,逐口抽吸时烟芯的温度分布和关键成分的逐口剩余量,同时检测表征了电加热卷烟烟芯内部温度场的体积平均温度和三维温度场。结果表明:①不同抽吸曲线(方形波和钟形波)下,烟芯不同位置的最大温差<10℃,烟气关键成分逐口剩余量最大相对偏差<5%。②抽吸容量不同时(35~55 mL),烟芯不同位置最大温差<20℃,烟气关键成分逐口剩余量平均相对偏差<10%。③电加热卷烟烟芯体积平均温度随抽吸过程呈锯齿形上升变化。To study the temperature distribution and the puff-by-puff release behaviors of key smoke components of an electrically heated cigarette(iQOS),temperature distributions in the tobacco section and the residual contents of the key components were determined under two different smoking profiles.The volume averaged temperatures and the three-dimensional temperature fields in the heated tobacco section were determined.The results showed that:1)By comparing a square-puffing profile and a bell-puffing profile,the maximum temperature difference between different positions of the tobacco section was less than 10℃,and the maximum relative deviations among the residual contents of the key smoke components were less than 5%.2)By comparing different puffing volumes(35-55 mL),the maximum temperature difference between different positions of the tobacco section was less than 20℃,and the averaged relative deviations of the residual contents for the key smoke components were less than 10%.3)The volume averaged temperature in the tobacco section of the electrically heated cigarette gradually increased with the puff number and displayed in a zigzag pattern during puffing.
