The strength of the Asian summer monsoon is known to be notably driven by Earths orbital parameters over the last millions of years.Stable oxygen isotopic records of cave carbonates from southern China are dominated by climatic precession cycles of～23-thousand years duration driving summer precipitation intensity.

新一代厘米分米波射电日像仪已在内蒙古明安图观测站建成。在调试运行与试观测期间,得到了一些太阳爆发活动事件的观测结果。如2014 年11 月11 日04：22 开始的耀斑事件,该耀斑为日面中心的一个C 级耀斑,SGD 数据将与该耀斑一起发生的射电爆发事件归于该耀斑事件。这也符合经典耀斑爆发图像,即耀斑初期非热粒子会产生射电和高能辐射,加热大气后导致软X 射线辐射增强,达到峰值。可是,我们的成像结果却
超导相变边缘探测器(TES)在适用波长范围、噪声特性、响应线性度等方面比其他热探测器具有明显优势。目前,TES 阵列在地面毫米波天文观测已得到成功应用,并为下一代空间天文观测提供了有力的技术积累。此外,应用TES 探测器的太赫兹远距反射式成像、光纤耦合单光子探测等实验演示使TES 在安全检测、量子通信等领域的应用潜力逐步显现。在此背景下,我们开展了TES 制备和特性研究工作。我们对实验室制备的Ti
先前脉冲星射电辐射未考虑环区，伽玛射线辐射只考虑外间隙区。新观测显示，无论射电还是伽玛射线辐射，都应考虑环区。对先前理论工作的一些问题进行讨论。
