We present results from a pulse timing analysis of the
accretion-powered millisecond X-ray pulsar SAX J1808.4–3658 using
X-ray data obtained during four outbursts of this source. Extensive observati...

X-ray Emission Characteristics of Flares Associated with CMEs
X-ray flares: rise time duration peak intensity CME:linear velocity acceleration
2009/5/6
We present the study of 20 solar flares observed by “Solar
X-ray Spectrometer (SOXS)” mission during November 2003 to December
2006 and found associated with coronal mass ejections (CMEs) seen by
...
We present some methods of X-ray data analysis employed in
our laboratory for deducing the physical parameters of flaring plasma. For
example, we have used a flare well observed with Polish instrum...

利用资源一号卫星和神舟二号留轨舱上搭载的高能粒子探测设备对2001年2～6月同一时段内的资料进行了对比分析. 神舟二号飞船X射线探测器的观测结果反映的空间高能电子的分布, 表明在400km的较低高度上, 地理纬度40°附近以及SAA地区也可以观测到数百keV的高能电子. 资源一号卫星的探测结果显示了在800km高度附近, 同一时段内若干兆电子伏特的高能电子的全球分布. 后者出现的最低地理纬度和相...
小角X射线散射中porod正偏离的校正
Ｘ射线小角散射分析 Porod定理 正偏离校正
2007/12/24
摘要 当散射体系中除散射体外还存在微电子密度起伏时，实测散射强度将形成对Porod定理的正偏离，从而使散射体的散射失真。提出了一种在长狭缝准直条件下应用模糊强度校正正偏离的方法：作出In[q^3I(q)]～q^2曲线，用公式n[q^3I(q)]=InK'＋σ^2q^2拟合大波矢区直线，求出斜率σ^2，作出In[q^3I(q)]-σ^2q^2～q^2曲线即为无偏离的Porod曲线，由此曲线再还原出无...
碳化硅多型体连生现象的X射线研究
2007/12/12
本工作用劳埃法对分布于三十二炉的四百多个碳化硅单晶进行了类型分布、连生规律和结构完整性等的分析。大量的观察表明,碳化硅片状晶体中的共轴平行连生是一种普遍的现象,二种以上类型的连生占晶体总数的三分之二。文中列出了各种连生类型的统计。系统地报导了SiC晶体连生状况的X射线法实验结果。对各炉晶体所作的类型分布的分析表明,不同的制备条件下影响较大的是颜色和结构完整度。类型分布的规律性并不明显,邻近的晶体类...

2007/12/12
本文提出了一种研究碳化硅多种类型连生的晶体中连生次序的实验方法。用超声波研磨法将极硬的薄片状碳化硅单晶逐层磨薄并逐次摄取双套劳埃照片。对劳埃法得出的SiC多型类型数据的分析可以确定各种连生多型体的次序和比例。用一晶体的实验结果对Mitchell的碳化硅多型性机理作了讨论。
