先秦"动·之(其)·名"结构的重新考察

在前人研究的基础上本文对先秦“动·之(其)·名”结构作了重新考察,进一步论证了“之”可作领格,“其”可作宾格。认为在某种条件下,“其”也可等于“之”,“取类动词·其·名”和“取类动词·之·名”一样,属于等效双宾结构。

从边疆到腹地:中国多元民族的不同类型——兼论“多元一体”格局

“多元一体格局”这样的概括 ,对演变至今的中国历史及其多民族结构提供了一种有用的认识框架。但无论从历史、地理还是族群文化等方面来看 ,其值得论证、展开的地方还很多。理论上讲 ,“一体”有待界说 ;现实当中 ,“多元”尚不平衡 ;而从腹地到边疆、从大陆到海岛 ,各相互有别的诸“元”差异 ,也还需要深入分析和研讨。联系中国历史上的帝国治理传统 ,从“边疆”和“腹地”两个角度及其相互对照试作论述 ,对多元之“元”及其所体现的不同之“多”做出探讨。     

项目决策中“不可行性论证”的几点思考

重大项目决策前进行“可行性论证”已经成为一项常规制度,但“不可行性论证”却尚未引起必要的重视。本文分析了单一可行性论证的缺陷和原因,阐述了“不可行性论证”对于科学决策的重要意义,提出了解决“不可行性论证”的制度机制。

对“用笔”与“结构”关系的再认识

关于书法“用笔”与“结构”的关系问题,历来有不同的见解．复旦大学出版社出版的《大学书法》,提出“用笔产生结构”的观点,被认为是“在较高立点上认识和把握了两者的关系”．对此,笔者有不同看法．从赵孟“书法以用笔为上”提出的背景情况,用笔与结构各自的内容含义,以及点画与用笔和结构之间的关系进行了深入地分析、论证,结论是：结构统领点画和用笔的变化,用笔服务和服从于结构造型的需要．

走出认识的误区--关于议论文体的"三要素"问题

文章学界对“三要素”的理解尚不科学。论点应是议论文中被论证或不对别的观点进行论证的观点。据此可将论点从众多观点中区分出来。论据是论证论点的客观实在性事实材料。分论点、被逻辑学当作推理前提的判断及神话、寓言、比喻性材料都不是论据。论证只是证明论点的过程。论点是一切议论文的要素;论证只是论证型议论文的要素;论据只是运用论据论证和综合论证型议论文的要素;三者的要素性有逐渐递减的趋向。论点对论据具有制约关系。论据对论点具有支持关系,这要求选取具有“反向求证”意义的论据或增加其数量。论证对论点和论据具有阐释关系,论证实为或由论点向论据或由论据向论点或两头对接式阐释。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

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.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.

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.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
