Abstract：
Based on the relativistic hydrodynamic model,the dilepton production in the quark-gluon fireball is studied.It is found that with increasing initial temperature the total dilepton yield mconotonicly goes up aftera plateau for the quark-gluon fireball of zero baryon number and shows a peak for the baryon-rich quark-gluon fireball.Such a characteristics as a signal of the quark-gluon matter formation in the collision could be tested in future experiments at CERN and Brookhaven.
