Abstract
We investigate the dynamics of a relativistic fireball which decelerates as it sweeps up ambient matter. Not only the radiative and adiabatic cases, b ut also the realistic intermediate cases are calculated. We perform numeric al calculation for various ambient media and sizes of beaming expansion, an d find that the deceleration radius R-0 may play an important role for the hydrodynamic evolution of GRB afterglow.
