初探现代远程开放教育的教与学

与传统的教育相比较现代远程开放教育在教与学方面存在着一些优越性，但目前推行现代远程开放教育仍然存在一定的制约因素，通过在开放教育教学中的几点尝试浅淡如何加强现代远程教育的教学工作。     

关于现代远程开放教育学生思想道德建设的思考

现代远程开放教育的人才培养模式与传统的高校人才培养模式既有共同点，：又不完全一样。必须认真研究现代远程开放教育学生思想道德建设的重要性、特殊性，正确认识面临的机遇和挑战，探索适合现代远程开放教育学生思想道德建设的原则、方法和载体，以求现代远程开放教育的培养目标落到实处。     

浅谈远程开放教育基层教师角色转换

根据现代远程开放教育的特点和中央电大开展的“人才培养模式改革和开放教育试点”的要求，结合基层电大在开放教育中所处地位以及两年多来的实践经验，提出基层电大教师在远程开放教育中的角色转换应定在“导”上，即指导、辅导、疏导和督导。     

我校召开现代远程开放教育研讨会

为交流我校现代远程开放教育的研究成果，进一步深化教育教学改革，2005年3月22日，校科技处、成教处、实验实训中心联合举办了“镇江高专现代远程开放教育研讨会”。此次研讨会由科技处唐祥金处艮主持，校领导、系部和有关部门领导、开放教育任课教师等近40人出席了会议。     

现代远程开放教育精神文明建设模式探讨

研究现代远程开放教育的精神明建设有着十分重要的意义。现代远程开放教育精神明建设面对教育观念、对象、时空、形式、资源以及环境等6方面的特殊要求，应当遵循“两全”统筹、“两手”并重、“两主”协调、集散结合、虚实互补等原则。现代远程开放教育精神明建设(思想道德建设方面)的一般模式主要有：学生自主探究教育模式，学生参与体验模式，交互合作交流模式和教师主导交互沟通模式。

统筹规划优化组合加强远程开放教育资源建设

“中央广播电视大学人才培育模式改革和开放教育试点”项目的开展，确立了中国广播电视教育的发展方向。整个电大系统对现代远程开放教育这一人才培养模式改革进行了积极的探索，取得了许多成功的经验。但是，各自为政所带来的小而全等不足逐渐显现出来，直接影响到试，占、项目的深入进行。因此，必须充分发挥系统优势，统筹规划，合理分工，优化组合，加强现代远程开放教育资源建设。

后现代主义视野下的现代远程开放教育

后现代主义对于知识的实用化与不确定性的强调、对于知识的多元性与生成性的推崇，以及对于智能机器的重视进一步凸显了以全民教育与终身教育、教育形式开放性与对话性、媒体技术的充分运用等为主要特征的现代远程开放教育的存在价值；与此同时，后现代主义的一些教育理念也在教育目的、课程设置、教学形式、课程评价等方面为现代远程开放教育的发展带来了种种新的观照和生长点。     

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.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

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.     

Jane Eyre——A Feminist In The 19th Century

In the 19th century the society was controlled by men, and women were just appendants of them, they had not any rights and freedom. But Jane was an exception, she showed some characteristics of early feminist. Jane showed her characteristics of feminism in three aspects: rebellion, equality, and independence. These characteristics were helpful to her success, and feminism is the only way out for women of that time.     

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-
