不同抽吸模式对主要减害降焦技术的影响研究

为研究不同抽吸模式对主要减害降焦技术的影响,测试了3种抽吸模式下卷烟样品中15种化学成分的释放量.研究表明:不同抽吸模式对主要减害降焦技术的影响程度不同,ISO模式下卷烟滤嘴通风率的改变对烟气释放量结果的影响程度较大;B模式下卷烟滤嘴通风率的改变对烟气释放量结果的影响程度减弱,烟丝配方调整对烟气释放量结果的影响程度增强;CI模式下烟丝配方调整对烟气释放量结果的影响程度较大.研究结果为新形势下新卷烟产品的研究开发提供参考.

Effect of different smoking regimes on main tar and harm reducing technology

In order to study effect of different smoking regimes on main tar and harm reducing technology, 16 different cigarettes were smoked under three smoking regimes, and the deliveries of 13 different fractions in mainstream cigarette smoke were analyzed. The results showed that:the influences of different smoking regimes on main tar and harm reducing technology were different, the effect of the cigarette filter ventilation rate was significant on the release of mainstream smoke in ISO smoking regimes; the effect of the cigarette filter ventilation rate on the release of mainstream smoke was decreased, and the effect of the tobacco structure on the release of mainstream smoke was increased in B smoking regimes; the effect of the tobacco structure on the release of mainstream smoke was greater in CI smoking regimes. These results can be used to design new cigarette under different smoking regimes.
