2003年10月18日,美国国防气象卫星计划成功发射搭载了专用传感器微波成像仪/探测仪的F-16卫星。然而由于天线自身热辐射和校准暖黑体的不稳定,第一个专用传感器微波成像仪/探测仪出现了一些重要的异常观测。美国海军实验室与美国国家海洋和大气管理局(NOAA)分别开发了两种算法来订正这些异常值。剔除了定标异常值后,专用传感器微波成像仪/探测仪资料目前在探空数据产品反演和资料同化中发挥了更加显著的作用。NOAA利用专用传感器微波成像仪已有算法生成了专用传感器微波成像仪/探测仪成像仪产品。此外,一些新开发的算法可以从专用传感器微波成像仪/探测仪资料中提取出云和降水的信息。在云冰云水的反演算法中,亮温是与云冰云水路径和粒子的平均直径相关的。利用一维变分反演系统,同时反演出了多数大气和地表条件下的大气温度、湿度以及水凝物的垂直廓线。在各种天气形势下,由专用传感器微波成像仪/探测仪资料反演得到的温度和湿度廓线的均方根误差通常分别小于2K和15%。为了同化专用传感器微波成像仪/探测仪资料,还发展了新的质量控制和偏差订正方法。在NOAA的全球预报系统中同化了专用传感器微波成像仪/探测仪资料后,对提高全球中期数值预报水平产生了中性和较小的正效果。

The focusing properties of azimuthally polarized hyperbolic-cosine-Gaussian (ChG) beam are investigated theoretically by vector diffraction theory. results show that the intensity distribution in focal region of azimuthally polarized ChG beam can be altered considerably by decentered parameters, and some novel focal patterns may occur for certain case. On increasing decentered parameters, ring shape of focal pattern can evolve into four-peak focal pattern, and azimuthal field component affects focal pattern more significantly than radial field component. Optical gradient force is also calculated to show that the focusing properties may be used in optical tweezers technique.

＜正＞It is well known that the dielectric constant of two-dimensional （2D） electron system goes negative at low electron densities. A consequence of the negative dielectric constant could be the formation of the droplet state. The droplet state is a two-phase coexistence region of high density liquid and low density "gas". In this paper, we carry out energetic calculations to study the stability of the droplet ground state. The possible relevance of the droplet state to recently observed 2D metal-insulator transition is also discussed.

The Sixth World Congress on Computational Mechanics in Conjunction with the Second Asian-Pacific Congress on Computational Mechanics

作者： L.Zhou ,W. x.Zheng School of Quantitative Methods and Mathematical Sciences, University of Western Sydney, Penrith South DC, NSW 1797, Australia

This paper presents a novel numerical method, the moving least square ritz method (MLS-ritz), to analyse the vibration behaviour of classical thin plates. A set of points is pre-selected on a plate domain and boundaries and the ritz trial function for the transverse displacement of the plate is established through the moving least square technique [1]. The weight function in the moving leastsquare technique is chosen to be ω(r)=(1-r2)n, where , d is theradius of support and n is an positive integer. The boundary conditions of the plate are satisfied by forcing the boundary points to meet the geometric bqundary conditions of the plate via a point substitution technique. Table 1 presents the convergence and comparison studies for a simply supported plate and a clamped square plate. It shows that the MLS-ritz method can obtain accurate frequency parameters for the considered cases. Comparing to the existing ritz methods, the proposed MLS-ritz method is highly stable and accurate and is extremely flexible for dealing with plates of arbitrary shapes, different internal point and line supports and boundary conditions. Several selected cases for plates of various shapes and support conditions are also presented in the full paper to demonstrate the versatility and accuracy of the proposed MLS-ritz method. The authors believe that the MLS-ritz method can be further developed to be a powerful numerical tool in computational mechanics.

晶格能U是晶体最重要的性质之一。并且利用他还可以计算各种性质(例如电子亲和势)。在研究很多化学及物理过程时(特别是热化学过程)这个量是十分重要的。自Partington一书出版及Pritchard评论性文章发表以后,几年来又发表了一些有关计算晶格能U的文章。这就说明了研究者们力图寻找比较简单的计算晶格能的方法,并修正及充实最基本的晶格能数据。以下我们将对最近发表的工作作一简短的概述。提出方程式:
