| 摘 要： | 本文将γ爆发事件分成三类,并认为第二,三类γ爆源于老年中子星且爆发谱由热轫致辐射、磁轫致辐射以及湮灭辐射谱组成。结果表明:①我们的假定可很好地解释第二、三类γ爆;②发射谱的性状依赖于发射区的磁场;③对于每个γ爆,它源于同一中子星的不同发射区。

| Abstract: | The observed gamma ray burst(GRB) events are divided into three kinds, and it was assumed that the second and third kinds of GRB' s originate from the old neutron stars and GRB spectra consist of hot bremsstralung, magnetobremsstralung and positron-electron annihilation radiation spectra. According to these suppositions, GB80982 and GB250378 are fitted, the results are at follow are (1) our suppositions can explain the second and third kinds of GRB spectra better;(2) the behavior of GRB spectrum depends on the magnetic field strength in the emitting regione; (3) each GRB comes from different emitting regions in the same neutron star. |
