Abstract：
Based on thermodynamic relations, the initial values of the quark gluon system from relativistic nucleus-nucleus collisions are obtained. Using these initial values we have studied the dilepton production on the basis of the relativistic hydrodynamic model, and found that with increasing incident energy a characteristic plateau indicating the formation of the quark-gluon plasma appears in the total yield, which may be tested in future experiments in CERN and Brookhaven.
