Abstract：
Non-central Au+Au collisions at s_NN=200GeV are studied with the RQMD model. The dependence of elliptic flow on freezeout radius of final particles is analized. We find that elliptic flow increases with freezeout radius firstly,and then decreases, with a maximum value at the original size of the surface. The results show the different evolution of pressure gradient in different direction. The method to analyze the pressure gradient with mean radial velocity is used.
