Abstract：
Based on the Lurie model,a convenient scheme is constructed for calculating the equation of state approximately.The parametric equaion of state is given in the Lurie model.The phase diagram of the model shows the existence of critical point separating first order from second order chiral phase transition.The careful analysis of isotherms of pressure versus net baryon number density suggests the existence of overheat and overcool metastable state and the coexistence of broken phase and normal phase.
