Abstract：
Baed on the BUU Model, the equilibrium process has been discussed in intermediate energy heavy ion collision, and some related physical quantities, collective flow, temperature and chemical potential have been discussed. Through our studies, we have found that the local equilibrium reaches at a certain time step. The local equilibrium begins from the central region. And for the peripheral collision, the local equilibrium has also been obtained. The temperature and chemical potential for the equilibrium is 5一7MeV and 30MeV, respectively.
