Abstract：
The time processes of collective flow were calculated by use of BUU equation with momentum dependence mean field and nucleonhucleon collisions in medium.It is shown that the momentum dependence mean field effect and the medium effect on the collective flow are obvious and sensitive to impact parameter and bombarding energy.
