一、卷烟纸的选择：卷烟纸有助于减少焦油放出量，主要有两个因素：１、燃烧率控制，达到一定抽吸次数（口数）；２、稀释度的增减，使烟雾浓度得于稀释。（一）燃烧率的控制：当卷烟纸卷制成烟支后，它的燃烧率就主要决定于此卷烟纸的透气度值的大小，透气度的单位：ＣＯ... First, the choice of cigarette paper: Cigarette paper helps to reduce tar release, there are two main factors: 1, the combustion rate control, to achieve a certain number of suction (number of ports); 2, the dilution of the increase, so that the concentration of smoke To dilute. (A) the combustion rate control: When the cigarette paper made into cigarettes, its combustion rate is mainly determined by the size of the cigarette paper breathability, the permeability of the unit: CO ...
