Abstract: | Using entropy density of Dirac field near the event horizon of a
rectilinear non-uniformly accelerating Kinnersley black hole, the
law for the thermal radiation of black hole is studied and the
instantaneous radiation energy density is obtained. It is found that
the instantaneous radiation energy density of a black hole is always
proportional to the quartic of the temperature on event horizon in
the same direction. That is to say, the thermal radiation of a black
hole always satisfies the generalized Stefan--Boltzmann law. In
addition, the derived generalized Stefan--Boltzmann coefficient is
no longer a constant, but a dynamic coefficient related to the
space--time metric near the event horizon and the changing rate of
the event horizon in black holes. |
