Abstract：
Form the Lagrangian of QHD Ⅱ, the thermdynamic potential is given in the formalism of finite temperatrue field theory through introducing the effective nucleon mass and effective chemical potential. We analyse the equations of state and find there is a new phase transition in the region of high temperature for the nuclear matter. At last, we give the phase transition diagram.
