摘　　要：以超细碳酸氢钠粉末作为示踪粒子,并使用基于互相关算法的DPIV系统对不同抽吸容量下卷烟燃烧区的速度场进行了测量。结果表明,随着抽吸容量的增大,卷烟燃烧区速度场变活跃;与未点燃卷烟相比,点燃卷烟燃烧产生的烟气对燃烧区速度场有较大影响,烟气的热浮力明显改变了卷烟在抽吸时速度场的变化趋势;随着抽吸容量的增大,卷烟燃烧区内烟气对速度场的影响相对减弱。The velocity characteristics of cigarette combustion area under different suction capacities was studied by using the Digital Particle Image Velocimetry（DPIV） system which is based on cross-correlation algorithmand uses superfine sodium bicarbonate particles as tracer particles. The results showed that with the increasing of suction capacity, the velocity field becomes more active. The flue gas has a great impact on the velocity of combustion field and obviously changes the velocity field variation trend. And with the increasing of suction capacity, the effects of flue gas on velocity field are relatively weaker.
