受温度及密度等环境效应影响,温稠密物质的电子结构发生显著变化,其理论描述非常复杂,精密实验测量亦极其困难.本文发展了基于X射线荧光光谱研究温稠密物质离化分布的实验方法,结合理论研究有助于深入理解温稠密物质的电子结构变化.在万焦耳激光装置上,设计特殊构型黑腔复合加载产生数十eV、近固体密度的稠密Ti物质,利用激光辐照V产生的热发射线泵浦Ti的荧光,并采用晶体谱仪诊断样品的X射线荧光光谱.实验中获得冷样品和加载样品的荧光光谱,观测到加载样品K_(α)及K_(β)荧光谱线相对于冷样品光谱在高能侧的显著变化,结合理论计算解释了加载样品荧光谱线的变化主要来源于其温度上升后离化分布的改变,建立了基于X射线荧光光谱的温稠密物质离化分布实验研究能力.

研究各向同性微细颗粒石墨ZXF-5Q的微结构及熔盐浸渗特性。使用光学显微镜、压汞仪、真密度仪、透射电子显微镜、X射线衍射仪以及拉曼光谱仪,对其气孔、煅烧裂纹、Mrozowski裂纹及晶体结构进行表征。结果表明,ZXF-5Q拥有均匀分布的气孔,非常小的入孔孔径(0.4μm),数量众多的透镜状Mrozowski裂纹以及良好的晶体结构。熔盐浸渗实验在不同压力(分别为1、3、5个大气压)650℃环境下进行。利用扫描电子显微镜和X射线能谱仪对其浸渗特性进行了观察分析。研究表明,由于其非常小的入口孔径,ZXF-5Q在5个大气压外加压强环境下依然可以很好阻止熔盐浸渗。尽管没有浸渗发生,在ZXF-5Q内部可以发现球形熔盐颗粒,可能是熔盐蒸汽凝结造成的。

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.
