Abstract：
From the full stopping scenuio, the dilepton producdon in the baryon-rich quarktgluon fircball is studicd based on a reladvisdc hydrodynamic model. It is found that with increasing incident cnergy a characteristic plateau indicadng the formation of the baryon-rich quarktgluon matter appears in the total yield. This obvious characteristic can be tested in future experiments at CERN and Brookhaven.
