英文摘要：
Soot is one of the important combustion products,which play a key role for radiative transfer in various areas of engineering.Based on the improved RADCAL program,three soot radiative models were employed to investigate the non-gray radiation from combustion products between two planar plates.The spectral emissivity,total emissivity and intensities of soot and gases mixtures（soot/H_2O,soot/CO_2,soot/H_2O/CO_2）were considered in present paper.These comparisons can provide the basis for the research of radiation heat transfer characteristics under combustion mode.
