【摘要】 Elliptic flow for non-central Au+Au collisions at s NN =200 GeV is investigated with a 2+1 dimensional hydrodynamic model.We analyze the softening effect by the velocity along the axis.The contribution of the elliptic flow from the QGP phase,mixed phase and hadron gas phase is studied.The relation between the sound horizon and evolution of the elliptic flow is discussed.
