| 英文摘要 | The statistical properties of the soft gamma repeater sgr j1550-5418 are investigated carefully. we find that the cumulative distributions of fluence, peak flux and duration can be well fitted by a bent power law, while the cumulative distribution of waiting time follows a simple power law. in particular, the probability density functions of fluctuations of fluence, peak flux, and duration have a sharp peak and fat tails, which can be well fitted by a q-gaussian function. the q values keep approximately steady for different scale intervals, indicating a scale-invariant structure of soft gamma repeaters. those results support that the origin of soft gamma repeaters is crustquakes of neutron stars with extremely strong magnetic fields. |
