Numerical calculation of emissivity using bi-spectrum mode

The principles and characteristics of a new scattering model named as bi-spectrum model (BSM) is introduced briefly in this paper. Using BSM to calculate the scattering coefficient, emissivity is calculated under different situations by using the simple relationship between scattering coefficient and emissivity. The results are compared with experimental data, also with the value calculated using the integral equation model (IEM), and validate the rationality of BSM.
