摘要

A new approach, called DRESOR (Distributions of Ratios of Energy Scattered Or Reflected) method, based on Monte Carlo methods, is developed to solve the radiative transfer equation. The method was applied to a gray plane-parallel medium filled with isotropic scattering and absorption media bounded by cold back boundaries and exposed to collimated irradiation. Using this method, the intensity with high directional resolution at any point can be obtained with high precision and without the requirement of radiative equilibrium and alterative computation.
