XMM-Newton observations of the supergiant fast X-ray transients XTEJ1739-302, IGRJ08408-4503 and IGRJ18410-0535
XMM-Newton supergiant X-ray transients XTEJ1739-302 IGRJ08408-4503 IGRJ18410-0535
2011/9/26
We report here on the XMM-Newton observations of the three supergiant fast X-ray transients (SFXT) XTE J1739-302, IGRJ08408-4503, and IGRJ18410-0535. For the latter source we only discuss some prelimi...

In this paper, we study the evolution of vector magnetic field of AR 10656 by using the observations of Huairou Solar Observing Station (HSOS, China) and Big Bear Solar Observatory (BBSO, USA).The mag...
Concept of magnetic/current helicity was introduced to solar physics about 15 years ago. Earlier studies led to discovery of such fundamental properties as hemispheric helicity rule, and role of helic...

“嫦娥一号”卫星微波探测仪数据处理模型和月表微波亮温反演方法
“嫦娥一号” 微波探测仪(CELMS) 在轨定标 月球冷空 亮温算法
2009/8/25
“嫦娥一号”卫星(CE-1)微波探测仪(CELMS)是人类第一次在月球轨道上对月球表面进行探测的被动微波遥感器. 在发射前, CELMS在实验室进行了大量的关于系统响应参数和定标的试验, 但是由于月球轨道条件复杂, 特别是一轨之内温度变化很大, 使得辐射计的各个部件的温度变化剧烈; 冷空定标天线安装位置、月球轨道冷空背景的复杂性, 使数据处理变得非常严峻. 尤其是在轨两点定标数据的处理, 涉及冷空...
CELMS是世界上首次从月球轨道对月表进行探测的被动微波遥感器, 其探测的亮温是表面物理化学特性的直接反映, 包含了表面温度、介电常数、月壤厚度以及表面地形等的综合信息. 通过对微波辐射亮温特性的研究, 能够建立这些物理化学特征参数与亮温的关系, 从而达到对壳温的直接反演. 结果表明, 月壤厚度的分布范围多数在4~6 m, 5 m以上的厚度区域占全月的43%以上. 其次, 利用CELMS所获得的亮...
