Nonstatic solution of Dilaton-Maxwell compound field and Hawking radiation of its black hole

SINCE Balbinot studied the back reaction of the evaporation on the Hawking temperature of anonstatic radiating black hole by using and generalizing the method of Davies et al.,wideinterest has been aroused in this field.In general,radiation terms with Luminosity Lwere introduced into energy-momentum tensor in the course of deriving evaporating
