Abstract：
The equilibration in relativistic heavy ion collisions ie studied with relativistic BUU theory.It is found that the mean field still play an important role in addition to the collison term of the equilibration process in relativistic heavy ion collisions at energy arround 1GeV/n.The influence of the medium effects is studied.The light and medium systems do not reach complete equilibrium so that the concept based on the complete equilibrium is questionable for this case.
