Abstract

Mechanisms for the Energy source of g -ray burst are summarized. This includes: explosion of giant SN, collapse of magnetic white dwarf, birth of magnetic star, phase transition of neutron star. Besides, the influence of energy input of central pulsar and the environment on the afterglow of g -ray burst are mainly discussed. Finally, some prospective studies on the g -ray burst in the future are mentioned.

Key words	g -ray burst － mechanism － afterglow
