和而不同--国务院参事室研究中心设计

国务院事室研究中心工程，地处东交民巷这一历史信息密集街区。笔者移植“和而不同”这一传统理念应用于历史街区局部更新，从建筑形式、整体比例、细部尺度、材料选择几个方面努力，基本达到了预期的设计目标：融合与共生。

垂直偏振态He-Ne激光自混合干涉的实验研究

从实验上研究了频率分裂激光器中偏振态相互垂直的o光和e光的自混合干涉现象,因为o光和e光之间的模竞争效应,所以在o光和e光的反馈曲线中,最大值和最小值相互对应,在一个周期中,最大值出现的次数是一般反馈曲线的2倍,幅值的变化也是一般反馈曲线的2倍。     

郑和下西洋的出国门——五虎门考辨

对于郑和历次下西洋的出国门, 在国内外郑和研究著述中, 尚未见专文论述, 而在这个问题上, 自明朝 至今还存在一些误解在传讹, 很有必要澄清。通过考证, 论定郑和下西洋的出国门应是五虎门, 而非其他港口。对五虎门在海疆中地理形势和其地名渊源及古今行政隶属进行了考辩, 对五虎门的古今功能进行了考证, 建议在地方命名上保持著名国门的历史名称。     

Frictional Effects in Thin 3He Films

The recent high-precision torsional oscillator experiments of Casey et al. involving thin films of normal liquid ³He showed that the film decouples from the substrate with a time constant which is proportional to T ⁻¹ where T is the absolute temperature. We interpret this experiment by adapting a theory due to Meyerovich which was developed for dilute ³He-⁴He mixtures flowing between two relatively smooth plates. The analysis of the experiment confirms the central idea that varies as T ⁻¹. The variation of with film thickness, d, is affected by the change in the shape of the free surface of the film, due to van der Waals forces, as the film becomes thinner.     

Test results after refurbish of cryogenic system for smiles

Superconducting Sub-millimeter-wave Limb-Emission Sounder (SMILES) is to be operated aboard the Japanese Experiment Module (JEM) of the International Space Station (ISS) in 2009. SMILES uses two superconductor-insulator-superconductor (SIS) mixers for sub-millimeter-wave atmospheric observation and they are cooled to 4 K levels by a cryogenic system with a two-stage Stirling cooler, a Joule-Thomson (JT) cycle cooler and a cryostat composed of three stages. Two-stage Stirling cooler precools the JT circuit and also cools radiation shields in the cryostat. JT circuit has three tube-in-tube type heat exchangers and an orifice for JT expansion in the cryostat. The cryogenic system is built, tested and delivered.     

50 mK cooling solution with an ADR precooled by a sorption cooler

CEA/SBT is currently developing a 2.5 K-50 mK cooling solution composed of a small demagnetization refrigerator (ADR) precooled by a sorption cooler, equivalent to the high temperature stage of a two-stage ADR system. Thanks to the use of this dual technology, a low weight cooler able to reach 50 mK with a heat sink up to 2.5 K can be designed. Because the sorption cooler is probably the lightest solution to produce sub-Kelvin temperatures, these developments allow us to propose a solution to face the drastic reduction in the mass budget of space missions like SPICA or IXO. The European Space Agency (ESA) is funding the development of an engineering model able to produce 1 μW net heat lift at 50 mK. It is sized so that the sorption cooler provides an additional 10 μW at 300 mK. The ESA main requirements are an autonomy of more than 24 h and a recycling time smaller than 8 h. We present the design of the system able to meet these requirements as well as the expected performances and preliminary measurements.     

辽河断陷烃源岩有机地球化学特征

为了研究辽河断陷东、西部凹陷烃源岩地球化学特征的差异及其与油气形成的关系,利用 RockEval 和气相色谱-质谱联用仪（GC-MS）对断陷内古近系沙河街组烃源岩进行了详细的有机地球化学特征研究。 通过对 18 块烃源岩可溶有机质饱和烃进行 GC-MS 测试和生物标志化合物的分析,并分别在东、西部凹陷烃源岩饱和烃馏分 m/z 191 和 m/z 231 质量色谱图中检测到了松香烷和甲基甾烷系列化合物,显示出相同（近）层段烃源岩不同的生物标志化合物特征。 研究结果表明：东、西部凹陷相同（近）层段烃源岩形成的古环境、母源输入等存在显著差异,这可能是造成东、西部凹陷烃源岩差异,并影响辽河断陷东、西部凹陷油气藏差异的重要原因。     

AVO技术在苏里格气田SQW区块的应用

SQW区块与苏里格气田总体构造特征相似,主要表现为地层平缓,构造圈闭不发育,以岩性气藏为主。由于区内各类岩石速度和密度等参数相互接近,应用传统的波阻抗反演方法难以识别盒8段气层,因此本文选用基于泊松比分析的AVO技术进行储层预测。参考Verm等提出的基于泊松比反射率的AVO技术,在区内利用岩石物理分析建立NI-PR彩色标定图板,通过彩色交会图解释技术分析实际地震道集AVO反演的NI和PR属性,可以获得较准确的含气储层空间展布信息。AVO储层预测结果与研究区内各井盒8段实际情况吻合率达80.5%。
