摘　　要：对SGRs的主要观测特征———在软伽玛射线波段的重复爆发及持久性的周期的X射线辐射———进行了回顾 ,介绍了SGRs的一些理论模型 ,其中磁星 (具有甚强磁场的中子星 )Soft Gamma ray Repeater (SGR) is a hotly pursued topic in recent year. This paper is an introduction to the progress on the research of SGR. Basic observational properties are reviewed. the main observed characteristics of SGRs are their repeated bursts in soft γ rays and persistent periodical X ray radiation. Several theoretical models of SGRs are briefly introduced, among them the magnetar (neutron star with ultra strong magnetic field) model accounts for their observations fairly well.
