康有为与近代文化过渡形态

我们过去强调康有为是近代中国的改革家、思想家和教育家是对的，但却忽视了他在改造中国传统化、会通中西化方面的历史地位。其实，他是一位学贯中西兼容古今的化理论家、诗人和章大家，是近代中国化的代表之一。他是中西兼容古今的化理论家、诗人和章大家，是近代中国化的代表之一。     

古代近代之交的杰出政治家陶澍——论陶澍的历史地位

陶澍是清朝后期中国经世学派在政治领域的杰出代表，而且，他和林则徐、魏源，是经世派转变为洋务派的关键人物，他的思想与政治实践开了中国近代洋务派经济改革的先河，并为洋务运动作了人才准备。陶澍还是湖南近代人才群体崛起的先导者。     

中德科技交流与合作的历史启示

众所周知,中国与德国在科学技术领域有长期交流与合作的历史.19世纪,中国就从德国的克虏伯、西门子等公司引进技术,装备近代工业和军队.蔡元培在1907年后三次留学德国,考察德国学术.他带回了洪堡(Humboldt)办大学的理念,对于改革北京大学,乃至中国的高等教育产生了重要的影响.他在创建中央研究院过程中吸收了德国的经验.     

刘彦:以外交史研究著名的外交家

刘彦一生未正式在外交部任职,却是中国近代有影响的外交家.他关于废除“二十一条”、收回旅大的提案,振臂一呼,全国响应.他研究中国外交史的著述丰富而影响深远.周恩来在青年时代受刘彦著作的影响很大,解放后曾向外交界推荐过刘彦的外交史著作.刘彦是中国近代第一代有民族意识、致力于维护民族利益的外交家和外交史学家.     

吴经熊与近代中国司法——以其在上海临时法院担任推事为考察对象

吴经熊被称为20世纪中国最享有世界性声誉的法学大家。他有幸直接见证并亲自参与了近代上海租界的司法改革,而且在很多司法领域都取得了重大的成绩。他自1927年至1929年底担任上海临时法院推事期间,审理了许多当时影响海内外的案子,是近代中国有节操的法官典范,推事生涯极为成功。     

张之洞教育思想对我国教育改革的启示

被赞誉为晚清"重臣名儒"的张之洞,在中国近代史上具有重要影响.他把兴学育才作为强国安邦的重大举措,一生与教育结下了不解之缘.其改造旧式书院、创设各类新式学堂、派遣留学生、构建中国近代教育体系的举动,开我国近代教育之先河,堪称中国近代教育的先驱.     

中国近代行政法规及其特点述论

中国近代具有现代意义的行政立法始于清末法制改革,在其后的40余年间,晚清政府、北洋政府、南京国民政府制定和颁布了数以百计的行政法律法规.这些行政法规是中国近代整个法律体系的重要组成部分,也是中国传统行政法律迈向现代行政法律的开端.中西法律文化冲突的时代色彩,现代法律形式和法律实质的对立和悖离,以及突出的阶级性和多变性,对中国近代的政治制度和行政管理产生了相当的影响.     

丁文江对中国地质地理学的贡献

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.

Perspherical Approaches for Electrons in Atoms and Charged Excitons in Quantum Wells

Instead of following Fock’s expansion,we solve the Schrodinger equation for some quantum mechanical manybody systems such as electrons in atoms and charged excitons in quantum wells in a similar way in hyperspherical coordinates by expanding the wave functions into orthonormal complete basis sets of the hyperspherical hannonics(HHs)of hyperangles and generalized Laguerre polynomials(GLPs)of the hyperradius.This leads the equation to     

Advances in broadband wireless communications under high-mobility scenarios

Future mobile communication systems aim at providing very high data transmission rates, even in high-mobility scenarios such as high-speed wheel-track trains, maglev trains, highway vehicles, airplanes, guided missiles or spacecraft. A particularly important commercial application is the strong and increasing worldwide demand for high- speed broadband wireless communications （up to 574.8 km/ h test speeds or 380 km/h commercial speeds） in railways, providing data, voice and video services for applications such as onboard entertainment services to passengers, train control, train dispatch, train sensor status handling and sur- veillance. In such high-mobility scenarios, there are a number of communication challenges, including fast hand- over, location updating, high-speed channel modeling, estimation and equalization, anti-Doppler spreading tech- niques, fast power control, and dedicated network architec- ture. Because signal transmission in very high-speed scenarios will inevitably experience serious deterioration, it is imperative to develop key broadband mobile communi- cation techniques for such high-speed vehicles.

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。     

Scale-based spatial data model for GIS

Being the primary media of geographical information and the elementary objects manipulated, almost all of maps adopt the layer-based model to represent geographic information in the existent GIS. However, it is difficult to extend the map represented in layer-based model. Furthermore, in Web-Based GIS, It is slow to transmit the spatial data for map viewing. In this paper, for solving the questions above, we have proposed a new method for representing the spatial data. That is scale-based model. In this model we represent maps in three levels: scale-view, block, and spatial object, and organize the maps in a set of map layers, named Scale-View, which associates some given scales.Lastly, a prototype Web-Based GIS using the proposed spatial data representation is described briefly.
