Abstract：
The Bjorken formula about maximal energy density in heavy ion collisions is modified,the effective way to increase the energy density is also analysed.The hydrodynamic equations and the equations of state in central and fragmental regions are discussed.It is pointed out that because of the energy diffusion caused by expansion of the system,it is lifficult to produce quark matter in fragmental region.For Au-Au collisions on the RHIC to be buict at BNL,the space-time region where phase transition occur d and the corresponding extent of impact parameter are predicted.
