Theoretical investigation is made on the unsteady radiative heat transferthrough an absorbing and emitting gray medium which occupies a semi-infinitespace bounded by a semitransparent gray plate. The system is initially in a uniformstate. At an instance the temperature of the plate is changed to a constant valuein addition to the imr>ose of a beam ?madiation throush the rlate. Thev are main-tained hereafter. It is found that the problem has two stages of time evolution:the initial stage and the large time stage, whose time scales as well as spatial scalesare different each other. At first, the temperature rises rapidly in the radiationlayer. The solution is solved in a form of time series expansion. In the large timestage, the temperature rises gradually in the asymptotic region. The solutionis solved by the matched asymptotic expansions.
