Abstract：
Under an Ansatz of density dependence of NNρ coupling,the phase transition of hot nuclear matter for Fumstahl,Serot and Tang's model is investigated.We have found that there is a limit pressure P_lim,when P>P_lim,the two-phase configuration and the liquid-gas phase transition cannot take place.
