RELATIVISTIC EFFECTS AROUND THE INNER REGION OF ACCRETION DISK AND THE "UV EXCESS" OF AGN

By comparing the various radiation fluxs from the inner region of accretion disks at Newtonian, Pseudo-Newtonian and relativistic frame, we point out that effective temperature of relativistic model is lower and less changeable than that of Newtonian model. So relativistic model is more suitable for single-temperature simulation of AGN's blackbody spectrum. A new simulation to the blackbody spectrum of some AGNs with "UV Excess" are performed by using relativistic accretion disk model and some characteristics of the region where the "UV Excess" generates are obtained in this paper.
