摘要
The wavelet basis functions are introduced into the radiative transfer equation in the frequency domain. The intensity pf radiation is expanded in terms of Daubechies' wrapped-around wavelet functions. It is shown that the wavelet basis approach to modeling nongrayness can be incorporated into any solution method for the equation of transfer In this paper the resulting system of equations is solved for the one-dimensional radiative equilibrium problem using the P-N approximation.
