We know that the discrete ordinates method is an important numerical method for solving transport equation. For the steady state transfer equations, the rationalities of this method have been proved by many authors. But there is no result whether this method is valid for nonsteady state transport equations. In this paper, we solve this problem by means of the theory of integrated semigroups[1-3] which was first considered by W. Arendt[1,2].
