Abstract：
From the full stopping scenario, we have studied the dilepton spectrum on the basis of the (3+1) dimensional RHE, and come to the conclusion that with increasing initial baryon density the dilepton production in invariant masses between 2 m_x to 1 GeV is shown to be suppressed, and an abnormal peak of the dilepton spectrum appears near the invariant mass 0.75 GeV if the baryon-rich quark-gluon matter is indeed created in ultrarelativistic nuclear collisions. These predictions will be tested in future experiments at CERN and Brookhaven.
