宋琬诗歌的艺术风格

宋琬是清初诗坛上的“国朝六大家”之一，在诗、词、曲、赋等各方面都取得了很高的成就，尤以诗胜。他的诗歌内容丰富，风格多样，很难对其作品做单一的概括和评价。但如果从其整体观照，宋琬的诗歌仍然在一定程度上体现出稳定的美学特征——“清刚”。     

关于宋琬生平的几个问题

针对近年来宋琬研究现状,文章将宋琬第一次被捕入狱的原因等五个问题提出来作了辨析,指出宋琬第一次被捕入狱同当时的“告密”风气和他的“文字馀孽”有关;宋琬第一次出狱后没有京官外任调芜湖抽分,而是在吏部继续供职;此后循序量移至顺治十八年晋升为浙江按察使,而不是山东按察使;宋琬两次入狱,身心备受折磨,但他乐天知命,顽强抗争,表现出“威武不能屈”精神,人品极高;宋琬康熙十一年起补四川按察使,十二年入蜀,十三年(1674)卒于京师。     

汪超宏《宋琬年谱》订补

汪超宏所著《宋琬年谱》,是近年来学术界发表的多种同题著作中学术价值最大的一部,但此书也有考订未详之处.方孝标《安雅堂文集序》、萧云从《同方尔止方位伯饮计部宋玉叔署中》和徐夜《杭州赠宋荔裳宪使先生》、《宋玉叔先生见示安雅堂诸刻集》等文献,汪著均未能采用.而这些文献所记宋琬与方孝标、萧云从、徐夜等3人的诸多交往均可系年,故据以对汪著作订补,以期促进对宋琬生平和交游的研究.

邓汉仪诗歌别集考略

邓汉仪不仅是清初重要的文学评论家和出版家,也是著名诗人,其对清初诗歌创作做出了很大贡献。但由于《诗观》等在乾隆年间受到禁毁,因而其诗歌作品大多散佚。我们通过文献考查,发现邓汉仪结集了《淮阴集》等一批诗歌作品集,这些诗歌别集既是邓汉仪诗歌创作的历程,也奠定了其在清初诗坛的地位。

论清代词人作品的文学价值

本文研究以纳兰性德为代表的清初著名词人,对他们的词风、写作手法及其作品在中国文学史中的价值和历史意义进行探讨和分析。     

张缙彦流放宁古塔期间作品的文化价值及特点

张缙彦是明末河南新乡人氏,清初因政治原因被流放到边寒的宁古塔地区。他的作品是流人文学的代表之一,对于考察宁古塔地区宗教和文化等方面有独特的价值。流人文学的另一个特点是"中原之思"写"北方之景",这在张缙彦身上体现得十分明显。他深受儒、释、道思想的影响,所以他在流放期间的作品不同于其他贬谪文学消极、苦闷的情感基调,而表现出纵情天地间的豁达和潇洒,并且含有深刻的道德观和哲理性。

"南洪北孔"遭难的深层原因

洪昇的<长生殿>和孔尚任的<桃花扇>是清初剧坛上的两朵奇葩,在清初产生了极大的反响.然而,两部剧本的作者,却在前后仅十年的时间内,相继遭难.洪昇和孔尚任之所以遭难,是因为他们的作品有着惊人的相似之处,那就是两剧在内容、创作动机、演出效果诸方面都触碰了清初统治者的忌讳.     

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.     

Exciton Seebeck in Molecular Systems

Various applications relevant to the exciton dynamics,such as the organic solar cell,the large-area organic light-emitting diodes and the thermoelectricity,are operating under temperature gradient.The potential abnormal behavior of the exicton dynamics driven by the temperature difference may affect the efficiency and performance of the corresponding devices.In the above situations,the exciton dynamics under temperature difference is mixed with
