英文摘要	We investigate the number of gamma-ray bursts in two particular strips of the sky using the data in 3B catalog of Burst and Transient Source Experiment (BATSE). One stripe is related to the plane in which the intergalactic globular clusters (R > 25kpc) and Galactic satellite galaxies (45kpc < R < 280kpc) concentrate, the other is concerned to nearby galaxies (1Mpc < R < 11Mpc). We find that the density of GRBs in these two strips is higher than that in other parts of the sky with significance 2.8 and 1.9 sigma respectively. We also compare the peak flux distribution of GRBs in these two stripes with that in other parts of the sky, and find no difference in the former stripe but a difference in the latter with a significant level alpha = 0.05. This is consistent with the distance scales of these two planes. So it suggests that at least a substantial fraction of GRBs may be related to those objects in these two planes and thus originate within 11Mpc.
