巴音布鲁克高寒区气象观测分析

本文通过2011-2013年中天山高寒无人区自建的自动气象站获取的稀缺气象资料,客观地揭示了观测区域的气象条件,给出部分气象特征参数变化特征,为中天山高山达坂区气象观测研究工作奠定一定基础,并得出如下结果：（1）迎风坡盛行风向SE、N,SE占35%,N占25%,N向风力集中4级以下,SE明显偏大,3级风比重15%,4级风比重7%,5级风比重4%;6级风比重1%,6级以上的风力几乎为零。背风坡主导风向角度范围在247.5°-337.5°,风力基本在6级以下,6级及以上风力出现概率不足1%。3-5级风占的比重较大。（2）日平均气温≤-10℃日数所占观测总日数的百分比,其值分别为：0.0%（恰西）、44.5%（江不肯达坂）、9.8%（江巴口子）、15.1%（铁力买提达坂）。恰西、江不肯达坂、江巴口子、铁力买提达坂4站日平均相对湿度≥80%的频率分别为5.9%、18.4%、16.1%和22.6%。（3）换算得出恰西、江不肯达坂、江巴口子、铁力买提达坂观测期间10m高度最大瞬时风速与小时平均风速分别为33.8/27.9m/s、41.0/27.3 m/s、25.7/17.7m/s、34.0/17.2 m/s。     

平湖油气田凝析油回注油藏对开发效果影响机理研究

凝析油回注油藏是平湖油气田开发过程中为应对海底输油管线而采取的一种工程应急措施。凝析油回注油藏会引起油层内流体渗流特征的变化，并进而影响油井恢复生产后的开发指标。从室内物理模拟实验和油藏数值模拟两方面开展凝析油回注油藏的影响效果分析，并根据研究结果提出合理的回注方式，不仅从机理上为解决海上油气田开发工程中所遇类似突发事件的处理提供了依据，而且在物理模拟实验和油藏数值模拟研究相结合对油藏基础研究方面提供一些重要的结论。     

Cosmic‐ray rejection for single spectroscopic CCD images by means of template matching

This article describes a novel algorithm for cosmic‐ray rejection in single spectroscopic CCD images. This algorithm is based on a variation of template matching. It focuses on identifying those pixels belong to spectra, while other conventional algorithms tried to locate the cosmic‐ray hits directly. The main principle is applying template matching to find suspicious blocks, which is followed by surface patching to locate the legitimate pixels accurately. Therefore, the rest pixels are the ones corrupted by cosmic‐ray hits. Meanwhile, almost all the parameters are automatically extracted from the images. Examples of its performance are given for both simulated and observed images. It shows an advantage of significantly low false alarm rate with relatively high detection rate (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Hydration effects on crystal structures and equations of state for silicate minerals in the subducting slabs and mantle transition zone

There are potentially huge amounts of water stored in Earth’s mantle, and the water solubilities in the silicate minerals range from tens to thousands of part per minion (ppm, part per million). Exploring water in the mantle has attracted much attention from the societies of mineralogy and geophysics in recent years. In the subducting slab, serpentine breaks down at high temperature, generating a series of dense hydrous magnesium silicate (DHMS) phases, such as phase A, chondrodite, clinohumite, etc. These phases may serve as carriers of water as hydroxyl into the upper mantle and the mantle transition zone (MTZ). On the other hand, wadsleyite and ringwoodite, polymorphs of olivine, are most the abundant minerals in the MTZ, and able to absorb significant amount of water (up to about 3 wt.% H₂O). Hence, the MTZ becomes a very important layer for water storage in the mantle, and hydration plays important roles in physics and chemistry of the MTZ. In this paper, we will discuss two aspects of hydrous silicate minerals: (1) crystal structures and (2) equations of state (EoSs).
