This paper proposes a rational, explicit and practicable approach for incorporating the spectral non-uniformity of absorption coefficient within a narrow band into a nongray analysis of radiative heat transfer in a nonisothermal field including a single infrared-active species. In the development of this new approach, attention is paid to securing rationality and explicitness even when the approach is applied to nonisothermal fields. This aim is achieved based on the fact that the line center of each absorption line does not move even if the gas temperature varies. Validity of the proposed approach is examined in detail trough comparison of the results obtained by the proposed approach with the results of line-by-line analysis base on a high-resolution database of absorption lines. It was confirmed in a typical nonisothermal field that the proposed approach can properly incorporate the influence of narrow band non-uniformity into a nongray analysis of radiative heat transfer in a nonisothermal field including a single infrared-active species.
