As the thermal radiation of coating surface on Low E glass is strongly influenced by its spectrum, the nongray band model in diffusing enclosure was used to numerically simulate the surface radiative characteristics of Low E glass in combination with the glass properties of absorptivity and transmissivity.

Bearing in mind the imperfections of computational model for Non gray gases radiation properties, the modification of a revised band model is proposed to take into consideration, the effect of wavelength, temperature, total pressure and ingredients of gases mixture, and Line broadening degree and index band parameters are presented to justify the computer code.

The axial dispersion in chromatography models was discussed with vector method and the effect of diffusion on the bulk flow flux with its partial quantity form was pointed too.
