Abstract：
In this paper the dilepton spectrum from an expanding hot nuclear matter is studied.Comparing with the spectrum from hot quark matter,we find that they are quite different.Especially the former with respect to the initial temperature or particle density is monotonic,the latter is non-monotonic.This may serve as theoretical examination for the production of quark phase transition.
