【Abstract】In order to investigate the effects of cigarette circumference on combustibility and smoke aerosol properties, the solid-phase temperature of combustion cones and gas-phase temperature in filters of cigarettes of the same brand with three circumferences (24.37 mm, normal; 20.06 mm, medium; 17.02 mm, slim) were tested by infrared thermal imaging temperature measurement method and thermocouple thermometry, respectively. A smoking cycle simulator and a fast mobility particle sizer were employed to determine the particle size of mainstream smoke aerosol under ISO mode. The results are as follows. 1) The solid-phase temperatures of the medium and slim cigarettes were 100 °C higher than those of the normal cigarette on average under puffing. 2) The gas-phase temperatures of filters at the tobacco ends of the medium and slim cigarettes were about 5 °C higher than that of normal cigarette. However, the gas-phase temperatures in the middles of filters of the three sizes of cigarettes tended to be consistent. 3) With the decrease in cigarette circumference, the average particle number concentration of aerosols for all puffs increased significantly, while the count median diameter (CMD) decreased, which indicated that the number of fine particles increased. 4) With the decrease in circumference, the average particle surface area of aerosols for all puffs increased significantly, and the area median diameter (AMD) reduced, which suggested that the total area of fine particles increased significantly.
