两种美国混合型卷烟产品，一种通风，在16个吸烟制度下吸烟。用这些方案确定的“焦油”、尼古丁、一氧化碳（TNCO）和水烟产率被示出形成与抽吸强度（抽吸量和抽吸频率的乘积）和总抽吸量（抽吸量和抽吸次数的乘积）相关的连续函数的一部分。这使得可以预测任何方案的产量，并得出结论，使用这些分析物的卷烟产品的表征可以通过使用单一吸烟方案来实现。相对于TNCO，（颗粒相）水产量随着强度显著增加。总抽吸体积与TNCO机器产量在一系列状态下线性相关，重复人类产量和尼古丁和茄尼醇保留在废过滤器。这些烟雾成分的浓度基本上与用于产生它们的制度无关。水的情况并非如此，水的烟雾产量随总抽吸量呈指数增加，其浓度随强度迅速增加。(C)2013 Elsevier Inc.

Two US blend style cigarette products, one ventilated, were smoked under 16 smoking regimes. 'Tar', nicotine, carbon monoxide (TNCO) and water smoke yields determined with these regimes, are shown to form part of continuous functions linked with puffing intensity (the product of puff volume and puff frequency) and total puff volume (the product of puff volume and puff number). This allows the prediction of yields for any regime and leads to the conclusion that the characterisation of cigarette products with these analytes is achievable from using a single smoking regime.The rate of increase of TNCO yields decreases as the puffing intensity increases, due to the more rapid burning of the tobacco available for smoking, although (particulate phase) water yield, relative to TNCO, increases considerably with intensity.Total puff volume is linearly related to TNCO machine yields from a range of regimes, to duplicated human yields and to the nicotine and solanesol retained in spent filters. The concentration of these smoke components is essentially independent of the regime used to generate them. This is not the case with water for which the yield in smoke increases exponentially with the total puff volume and its concentration increases rapidly with intensity. (C) 2013 Elsevier Inc.
