【Abstract】 It has been proved in this paper that the radial part of the Klein-Cordon equation can be reduced to the standard form of wave equation near an event horizon when a generalized tortoise coordinate is adopted in the general circularly symmetric 2+1 dimensional non-stationary space-time. The universal relations determining the location of event horizons and the radiation temperature are found.更多还原
