有效燃吸体积折算法判定卷烟主流烟气指标的研究

Determination of mainstream smoke index by effective burning volume conversion method

为探索卷烟规格对卷烟主流烟气指标检测及判定的影响,建立了标准烟支体积折算法,即以标准烟支的有效燃吸体积为基准对其他规格烟支主流烟气指标进行修正。研究表明:(1)经标准体积折算后,使不同规格卷烟的主流烟气指标有了较为科学的可比性,有利于检测口径的统一;(2)国际品牌卷烟在降焦减害方面要好于国内大部分卷烟产品,但国内少数低焦油产品也已具备了很高的降焦减害水平,说明国内卷烟在降焦减害方面仍有很大潜力可挖。

A standard cigarette volume conversion method was established to study effect of cigarette size on detection and determination of mainstream smoke,i.e.the amount of mainstream smoke of different sized cigarettes was amended based on effective burning cigarette smoke volume.Results show that（1） by standard volume conversion,mainstream smoke of different sized cigarettes were more comparable,which was conducive to the uniformity of testing methods;（2） international cigarette brands were better than many of domestic cigarette products in less tar,however,some domestic low-tar products already had a very high level in reducing tar and harmness,indicating that domestic cigarettes still had great potential.
