Abstract：
The characteristic dilepton mass distributions from the decay of high temperature-density quark-gluon matter in ultrarelativistic nucleusnucleus collisions were calculated via the relativistic hydrodynamics.Both longitudinal expansion accompanying transverse expansion of the matter and the effect of phase transition leading to the re-distribution of the temperature were considered.The characteristic phenomena which have been suggested as a test for the existence of quark-gluon plasma were given and provided as a theoretical basis of experiment.
