摘要：

We discuss a scenario in which the highest energy cosmic rays (CR's) and cosmological gamma-ray bursts (GRB's) have a common origin. This scenario is consistent with the observed CR flux above 10(20) eV, provided that each burst produces similar energies in gamma rays and in CR's above 10(20) eV. Protons may be accelerated by Fermi's mechanism to energies similar to 10(20) eV in a dissipative, ultrarelativistic wind, with luminosity and Lorentz factor high enough to produce a GRB. For a homogeneous GRB distribution, this scenario predicts an isotropic, time-independent CR flux.
