摘      要：Narrow-band transmissivities in the spectral range of 150 to 9300 cml and at a uniform resolution of 25 cm-1 were calculated using the statistical narrow-band （SNB） model with the band parameters of Soufiani and Taine, the more recent parameters of Andr6 and Vaillon, and the line-by-line （LBL） method along with the HITEMP-2010 spectroscopic database. Calculations of narrow-band transmissivity were conducted for gas columns of different lengths and containing different isothermal and non-isothermal CO2-H20-N2 mixtures at 1 atm. Narrow-band transmissivities calculated by the SNB model are in large relative error at many bands. The more recent SNB model parameters of Andr6 and Vaillon are more accurate than the earlier parameters of Soufiani and Taine. The Planck mean absorption coefficients of CO2, H20, CO, and CH4 in the temperature range of 300 to 2500K were calculated using the LBL method and different versions of the high resolution transmission （HITRAN） and high-temperature spectroscopic absorption parameters （HITEMP） spectroscopic databases. The SNB model was also used to calculate the Planck mean absorption coefficients of these four radiating gases. The LBL results of the Planck mean absorption coefficient were compared with the classical results of Tien and those from the SNB model.
