Abstract：
With the increase of the initial baryon density, the dilepton production in invariant masses between 2mπ and 1GeV is shown to be suppressed and an abnormal peak of the dilepton spectrum appears near the invariant mass0.75GeV if the baryonrich quark-gluon matter has been created in relativistic nucleus-nucleus collisions.These predictions are important for several large-scale experiments at CERN and Brookhaven.
