ABSTRACT
In computing effective radiation, spectral characteristics of gas radiation must be taken into consideration. For that purpose, the infrared spectrum 1~5μm has been divided into 41 wave bands. The spectral effective radiation ,q efwλ , in these 41 wave bands will be computed, respectively, and summed up to get effective radiation in 1~5μm. All the other spectrums are taken as one wave band, and gas can be assumed as transparent, only radiation between wall cells needs to be computed.
