Abstract：
The Bjorken formula about maximum energy density in heavy ion collisions is improved. An effective way to increase the energy density is analyzed. Hydrodynamical equations and the equations of state in the central and fragmental regions are discussed. It is pointed out that because of the energy diffusion caused by the expansion of the system, it is difficult to produce quark matter in the fragmentation region. For the Au-Au collisions at RHIC to be built in BNL, the space-time region for the formation of quark matter and the corresponding range of the impact parameter are predicted.
