摘　　要：A parton and hadron cascade model, PACIAE, is applied to follow the particle transport in partonic and the hadronic stages in 0%-5% most central Au+Au collisions at energies from SPS to RHIC. WeA parton and hadron cascade modal, PACIAE, is applied to follow the particle transport in partonic and the hadronic stages in 0%-5% most central Au＋Au collisions at energies from SPS to RHIC. We have determined the specific heat of hadron matter （π^＋＋π^-） in the hadronic final state and the specific heat of quark-gluon matter （u＋d＋g） in the partonic initial state in Au＋Au collisions as a function of the reaction energy （excitation function）. It turns out that the QGM specific heat is hard to survive the hadronization and there is not a peak structure in the specific heat excitation functions in studied energy region .
