摘　　要： 为了解吸烟机抽吸模式对卷烟主流烟气相关测量方法与结果精密度的影响,针对卷烟主流烟气的常规指标(抽吸口数、总粒相物、焦油、烟碱、CO)、烟草特有亚硝胺[TSNAs,N-亚硝基降烟碱(NNN)、4-(N-甲基-N-亚硝氨基)-1-(3-吡啶基)-1-丁酮(NNK)]、苯并[a]芘、羰基化合物(甲醛、乙醛、丙烯醛、巴豆醛)、苯酚、氢氰酸、氨、挥发性有机化合物(VOCs,1,3-丁二烯、苯)等17个测试指标,在ISO和加拿大深度抽吸(HCI)两种模式下开展了卷烟主流烟气系列测量方法的协同试验,按照GB/T 6379.2—2004/ISO 5725-2:1994的统计方法进行分析,获得了9个测量方法 6个测试水平(m)下的重复性限(r)和再现性限(R),并确立了r、R与m的线性拟合函数关系。结果表明:焦油、烟碱、CO的测量精密度显著优于其他测试指标,相对重复性限(r%)和相对再现性限(R%)分别约为10%和20%,其他指标的r%和R%分别为20%和45%左右;与ISO抽吸模式相比,HCI抽吸模式下卷烟主流烟气释放量显著增加,但测量方法的精密度对于绝大多数测量指标并没有明显改善;HCI抽吸模式下相关测试指标的精密度对m的依赖性显著较弱,部分指标的两种吸烟机型测试结果差异较大;烟气在HCI抽吸模式下的捕集过程中,吸烟机卷烟抽吸参数(如抽吸口数)稳定性相对较差。因此,当前典型的吸烟机设计并不能较好地满足深度抽吸条件下卷烟主流烟气相关分析物的稳健测量。 In order to study the influences of two smoking regimes [ISO and Health Canadian Intense（HCI）smoking regimes] on the precision of specific measurements and results of mainstream cigarette smoke, a series of collaborative studies were carried out using seventeen smoke analyte indices including, puff number, total particulate matter,tar, nicotine, carbon monoxide（CO）; N-nitrosonornicotine（NNN）, 4-（N-methyl-N-nitrosamino）-1-（3-pyridyl）-1-butanone（NNK）; benzo[a]pyrene（B[a]P）; formaldehyde, acetaldehyde, acrolein, crotonaldehyde;phenol; hydrogen cyanide（HCN）; ammonia; 1,3-butadiene, benzene. The results were statistically analyzed, the repeatability（r） and reproducibility（R） of nine methods at six delivery levels（m） were obtained according to GB/T 6379.2-2004/ISO 5725-2：1994 recommendations, and the linear regressions of m with r and R for each analyte were determined. The results showed that： the relative repeatability（r%） and relative reproducibility（R%） for tar, nicotine, CO were about 10% and 20%, respectively, while those for the other analytes werebetween 20% and 45%. The precision for tar, nicotine, CO under both repeatability and reproducibility conditions were clearly better than that for the other analytes. In addition, no significant improvements for measurement precisions were found under HCI smoking regime even though the analytes＇ yields were much higher than those under ISO regime. In contrast to the samples smoked under ISO regime, a much weaker correlations of linearity between m and r or R were obvious for most of the analytes under HCI regime.Meanwhile for some analytes, the measurement differences between the two type（rotary and linear） smoking machines were higher under HCI regime. Following the existing mainstream cigarette smoke collection, the stability of smoking machine＇s puffing parameters, such as puff number, were lower under HCI regime. These results indicated that the typical smoking machines are not optimised for the robust
