摘要：

We consider Single Black Holes (SBHs) of 10(3) M. as possible parent objects for cosmological GRBs. The latter are the result of the energy release of SBHs magnetosphere inhomogeneities. The percolation nature of this release yields a unique power law for the GRBs energy distribution that is E-beta (with beta = 1.7 - 1.8), i.e. the same observed in solar flares, flare stars and X-ray sources. The number of GRBs per year per galaxy is about 10(-2) - 10(-1) with total energy 10(47) - 10(50) ergs for beaming factor of about 10(-2) - 10(-5).
