| 摘 要： | 利用大气采样器、光学显微镜、CCD数码相机及图像处理系统设计了一套烟气气溶胶颗粒观测分析系统,分析了观测系统和图像处理及统计分析系统方法的可靠性,实现了烟气气溶胶颗粒的实时观测及其统计分析。试验结果表明,主流烟气气溶胶颗粒平均粒径为0.8~1.0μm之间,颗粒密度在1.6×107~2.9×107个/cm3之间,烟气气溶胶颗粒大小一定程度上与滤嘴的材料、长度、烟支长度等因素有关。此研究工作对卷烟降焦有指导意义。

| Abstract: | In order to realize real time observation and statistics analysis of cigarette smoke aerosol particles, a system made of atmosphere sampling implement, microscope, CCD cameras, and image processing system was established and reliability of the system and statistics method were analyzed. Results showed that the size of smoke aerosol particles were to some extent dependent on butt length and cigarette type. The average size of mainstream smoke aerosol particles exhibited from 0.8 μm to 1.0 μm with concentration from 1.6×107 to 2.9×107 particles per cubic centimeter. This research was of significantce in guiding future research for tar reduction in cigarette. |
