摘要：
A new relaxation scheme is exhibited to approximate the weak solutions of the M-1 model to simulate radiative transfer. This numerical method uses better wavespeed approximations than the current schemes. In addition, it is proved to satisfy all the required stability properties and the asymptotic preserving property.
