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.
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 )模型较合理地解释了现有的观测事
Following 20-years long silence in satellite magnetic survey after POGOs in1967～1971 and MAGSAT in 1979～1980,the magnetic satellites Orsted,Champ and SCAC were launched in February 1999,July and November,2000 by Denmark,Germany and Argentina,respectively.
自此之后,卫星磁测沉静了20年。
