Abstract：
The time processes of entropy production and collision number in intermediate energy heavy ion collisions were calculated by use of BUU equation with momentum dependence mean field and nucleon-nucleon collisions in the medium.The effects of momentum dependence mean field and nucleon-nucleon collisions in the medium on the entropy production and collision number are obvious and sensitive to impact parameter and bombarding energy.Especially these time processes reflect the properties of hot nuclear matter.
