摘要：

We have suggested previously that baryons in gamma-ray burst fireballs come from the surrounding walls that collimate the fireball. The efficiency epsilon(b) for generating blast energy can then be angle-dependent. The delayed onset of afterglow can be interpreted as being due to a baryon-poor viewing angle.
