Abstract：
Using QMD model the time evolution of Au+Au system at 100MeV/u is studied.For very central collisions the conditions for freeze-out and how the different physical quantities approaching equlibrium are investigated.The calculated results show that for 100MeV/u Au+Au at b=0fm,the maximum density can reach 1.6ρ₀ and after that the system expands to a low density region.A position correlated central flow is developed during the expansion stage.By studying the two pamicle reladve momentum spectrum it is able to separate central flow from random thenmal motion.The dependence of this central flow on E.O.S.is also discussed.
