Abstract :
Afterglows from most gamma-ray bursts, such as GRBs 970228, 970508, 971214, 980329 and 980703, decay slowly and steadily. These bursts are widely believed to be due to isotropic fireballs. However, they in fact can also be well fitted by a cylindrical jet model. It is proposed that these bursts are probably generated by cylindrical jets, and not necessarily by isotropic fireballs.
