Abstract：
A Simulation is carried out for five different phases of nuclear equation of state. thegas, the liquid, the super heated liquid, the super cooled gas and the mechanical instability of spinodal phases, which are obtained from a deasity, tempemperature, and momentum depen dent mean field for ¹⁹⁷Au at finite temperature T=6MeV in real space and in momenturn space The nuclear cluster is sorted a coalescence model. lt is demonstrated that the intermittent pattern comes from the mechanical ionstability of spaiodal phase and the criti cal behaviour comes mainly from the mechanical instability of spinodal phase while there is also a small contribution from the super heated liquid phases from the analyses of the conditional moments and the scaled factorial moments.
