Abstract : A recently introduced modification of the standard moments method, applicable to radiative transfer problems in planar, radiating, non-scattering media without polarization effects, is examined for the general N-th order approximation. The modification is essentially a canonical transformation of the standard moment equations. It is shown that the transformed system is not only equivalent, but essentially identical, to the discrete ordinates method. The transformation is useful in that it provides more insight into the relationship between the moments method and the discrete ordinates method. (Author)
