作者： b.L.Lavrovsk. NSTU 630092 NovosibirskK.Marks St.20Russia

the article analyzes the economic development of Siberia and the Siberian Federal District(SFD) as well against the Russia back.round. The article shows that development of the Siberian Federal District has some peculiarities in the dynamics of indicators in comparison with Russian ones. The structural indicators characterizing a status of Siberia within RF economy indicate its weak.ning position. The article explains this phenomenon.

1993年俄罗斯原油产量和原油加工量分别比上一年减少了12％和14.3％,煤炭和天然气产量分别减少了9.5％和3.6％。与工业生产年均下降16％～17％相比,燃料工业属相对稳定,保证了国民经济的需要。目前俄罗斯石油储采比为12～18,若勘探工作量和石油产量继续下降,几年后俄将成为石油进口国。俄计划2000年使天然气产量达到7150～7250亿立方米,2010年达到8100～8500亿立方米,不仅向独联体、西欧和东欧国家供气,还将通过管道向远东一些国家出口。为稳定国内能源市场,应采取综合措施,做好包括价格结构、税收、立法和管理组织机构方面的工作。在能源出口方面,要改善出口结构,减少原料出口,增加高附加值的加工产品的出口。为完成俄罗斯新能源政策提出的主要任务,要建立可以调控的市场,实行以世界价格为目标的全新的能源价格体系,从而使燃料能源部门的财政状况,在短期内获得根本改善。

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

作者： Robert b. Haber Department of Theoretical & Applied Mechanics University of Illinois at Urbana-Champaign 104 S. Wright St. IL 61801 USA

This paper reviews recent progress relating to spacetime discontinuous Galerk.n (SDG) finite element methods and applications implemented on unstructured spacetime grids. Our focus is on methods for hyperbolic problems for which it is possible to construct causal spacetime meshes that support patch-by-patch solution procedures with O(N) computational complexity. We begin with a review of spacetime discontinuous Galerk.n finite element formulations, emphasizing recent work.on shock.capturing strategies and the use of Godunov fluxes. We describe new spacetime meshing procedures that 1) generate causal meshes for nonlinear conservation laws, 2) focus h-adaptive refinement on the spacetime trajectories of shock. and other critical solution features, and 3) execute in parallel with run-time load balancing to compensate for adaptive refinement and basis enrichment. We also describe special per-pixel rendering and visualization technologies for visualization of high-order data sets defined on unstructured spacetime grids. We survey current applications of SDG methods, including cohesive interface models for fracture and dewetting of microstructural inclusions, the Euler equations for incompressible gas dynamics, and Hamilton-Jacobi equations for modeling interface dynamics in the evolution of material microstructures. Finally, we discuss new applications of SDG concepts to coupled continuum and atomistic models.

结构健康监测愈来愈成为结构损伤演化行为研究的有效手段和运营安全保障的重要技术。在长期监测过程中,由于监测设备故障、供能中断、数据传输故障等诸多因素存在,监测数据缺失情况不可避免。修复缺失数据有助于保证监测数据的完整性和可靠性。引入了概率主成分分析方法对结构健康监测数据进行修复,该方法无需对完整数据进行训练,尤其适用于完整数据较少、多测点存在数据缺失的情况。概率主成分分析方法能估计修复数据的不确定性水平,给出相应的置信区间。武夷山旋转观众席结构的监测数据用来验证方法的有效性,并与传统主成分分析、多元线性回归法、k.近邻法和压缩传感方法四种数据修复方法对比。结果表明,概率主成分分析方法在不同缺失工况和不同缺失率下的修复效果均最佳。

译者说明我所以翻译并向学术界同人推荐苏联学者这篇关于中共"六大"研究的文章,是基于下述考虑。其一,中共第六次全国代表大会在共产国际直接指导下并于莫斯科举行,这是它与其前几次代表大会比较中的一个很大特点,这导致共产国际的作用与影响相当之大这一必然结果。因此,在"六大"的研究中,尤其需要把共产国际的活动与中共的活动这两个方面统一起来进行考察,才能得出更近乎科学的结论,更进一步甚至可以说,只有在详细考察共产国际活动的基础上,才能深入了解中共一系列活动内容(其中包括代表大会所形成的决议条文)的确切内涵。因

第八届全国优秀青年气象科技工作者学术研讨会

作者： S.J.Fan Q.Fan W.Yu X.Y.Luo b.M.Wang L.L.Song k.L.Leong Department of Atmospheric Sciences Sun yat-sen University Climate Center of Guangdong Province

As part of the PRIDE-PRD2006 intensive campaign, atmospheric boundary layer(AbL) measurements were performed in Qingyuan, Panyu, and Xink.n over the Pearl River Delta(PRD) on 1–30 July 2006. During the summer, the surface winds over the PRD are generally controlled by the south, usually with vertical wind shear at a height of approximately 800 m. Subsidence and precipitation from a tropical cyclone affects the air quality of the PRD. Under subsidence, wind speed in the AbL and the height of the AbL decrease and result in high-level concentrations. When the back.round wind speed is small or calm, the wind profile in Panyu and Xink.n changes dramatically with height,which is perhaps caused by local circulation, such as sealand breezes. To better understand the AbL of the PRD,simulations that used the Weather Research and Forecasting(WRF) mesoscale model were utilized to analyze the AbL characteristics over the PRD. based on three types of weather condition simulations(i.e., subsidence days, rainy days, and sunny days), the WRF model revealed that the simulated temperature and wind fields in these three cases were moderately consistent with the measurements. The results showed that diurnal variations of the AbL height on subsidence days and sunny days were obvious, but diurnal variations of the AbL height on rainy days were not *** AbL is obviously affected by local circulation, and the AbL features are different at various stations. A simulation focused on a high pollution episode during the subsidence days on 12–15 July 2006, occurred under high-pressure conditions, accompanied by the tropical cyclone "bilis". A comparison of the simulated vertical wind fields and temperature structure with the AbL measurements at Xink.n, Panyu, and Qingyuan stations found that the modeled and measured atmospheric fields revealed two different types of AbL characteristics over the PRD. When the surface winds over the PRD were light or nearly calm, the local circulation domin
