摘要：

We consider interpolation-characteristic schemes approximating the radiative transfer equation corresponding to the P-1 model. The model equations are modified by adjusting the rate of radiation energy transfer. This correction can reduce the influence of nonphysical effects in calculating radiative heat transfer in a medium with nonuniform opacity.
