Abstract：
The thermalization,expansion and radial flow are discussed in the processes of intermediate energy heavy ion collisions via BUU model.Our results show that at lower energies,the thermalization is reached for the collision system,but at higher energies the global thermalization is violated and only local equilibrium exists.The expansion process in the heavy ion collision at medium energies is also discussed.
