本文介绍了1900+14和1806-20两个SGR的朱雀卫星观测的光谱和时间研究。X射线静态发射光谱可以用两个黑体函数或黑体加幂律模型很好地拟合。INTEGRAL发现的非热硬组分由PIN二极管检测，其光谱由INTEGRAL报道的幂律模型再现。XIS检测到SGR 1900+14的周期性P = 5.1998+/-0.0002 s，SGR 1806-20的周期性P = 7.6022+/-0.0007 s。脉冲分数与SGR 1900+14的爆发活性相关。
Spectral and timing studies of Suzaku ToO observations of two SGRs, 1900+14 and 1806-20, are presented. The X-ray quiescent emission spectra were well fitted by a two blackbody function or a blackbody plus a power law model. The non-thermal hard component discovered by INTEGRAL was detected by the PIN diodes and its spectrum was reproduced by the power law model reported by INTEGRAL. The XIS detected periodicity P = 5.1998+/-0.0002 s for SGR 1900+14 and P = 7.6022+/-0.0007 s for SGR 1806-20. The pulsed fraction was related to the burst activity for SGR 1900+14.
