The soot formation and oxidation characteristics of methane diffusion flames have been experimentally studied at the pressures from 0.2MPa to 0.4AMP. The measured spatially resolved soot volume fraction distributions indicated that there is a significant pressure effect during the soot formation process while the effect of pressure is relatively less obvious for the soot oxidation process. The increase of fuel concentration with pressure might be most responsible for the enhancement of soot formation through the pyrolysis and gas-phase reactions during a soot formation process. On the contrary, the decrease in oxygen diffusion velocity and the surface reactions during a soot oxidation process is the most likely to be responsible for the relatively small effect of pressure on it. The further information of soot panicle size. PAH concentration distribution and soot temperature will be experimentally obtained in the further in order to better understand the pressure effect.<br/>
