关于学分制的一些思考

推行学分制是教学管理制度改革的重要方面之一。培养高素质创新人才是实施学分制的目的，顺利推行学分制必须具备相应的条件，所以说推行学分制是一个不断创造条件，不断完善的过程，是一个系统工程。     

对学分制的思考

我国高等学校教育要与世界接轨,必须进行学分制的教学改革。本文探讨了学分制的特征及它的现实意义,对进一步推行学分制提出了有益的建议。灵活而富有弹性的学分制是高校教学制度改革的必然选择,同时我们更关注实行学分制将引发的一系列高校内部制度的改革。     

浅议我国高校学分制改革面临的问题及对策

学分制在我国高校的实施具有重要现实意义，加速我国高校学分制改革的步伐已势在必行。针对我国高校学分制改革普遍存在的问题——学生选课的盲目性，教学计划的弹性不够，课程设置不尽合理，选课指导工作缺乏力度等，文章提出了完善我国高等教育学分制教学管理体制的一些具体措施。     

广西高专院校实施学分制的制约与对策

随着我国的入世，教育的国际竞争日愈凸现．党在十六大报告中明确提出．教育是发展科学技术和培养人才的基础，在现代化建设中具有先导性、全局性作用，必须摆在优先发展的战略地位。高校教育要在竞争中立于不败之地，就必须丰富其发展的内涵，重新审视现行的各项管理制度，进行教学计划、课程管理、考试管理、学籍管理等方面的改革。然而，要使这些改革获得根本性的突破，在于推行完全学分制。当前．要在广西高专院校全面推行学分制．会遇上不少问题和困难。因此，必须更新教育观念，积极调整专业设置，加强学科建设，改进各项教育教学管理制度、措施．为实施学分制搭建运行平台。     

对我区高校实行学分制的思考

高校在学分制实施中的网络信息安全

学分制已经在高校中逐步实行起来，相对于以往的管理制度，学分制强调以学生为中心进行教学。对于高校中数以万计的学生，必须借助网络信息系统来实行学分制，而在学分制的实行中网络信息安全显得尤为重要。针对常见的网络安全问题，论述了保障网络安全的措施，提高网络安全系数使高校网络更好的为学分制服务。     

学分制实施方案的设计

随着经济体制改革的不断深化，实施学分制已势在必行。学分制实施方案设计，要以学分制理论为指导，又要遵循重视学生个性发展、优化智能结构、实行目标管理等原则。在完善学分制的过程中，必须注意解决教学计划弹性化、严格学籍管理和建立健全综合配套的管理制度等问题。     

学分制教学管理的改革与实践

高等学校在教学管理模式上逐步实现由学年制向学分制转变，是深化高等教育管理改革的必然趋势。由于各学校类型和定位不同，历史文化底蕴不同，学校资源环境的差异，实行学分制不可盲目照搬，必须根据学校的实际，建立一套适合本校特点的学分制管理模式，才能保证学分制实施后，在教学管理中起到积极作用。     

高校实行学分制的可行性与措施

学分制是以学生选课为前提，以学分作为计量单位衡量学生的学业完成状况。社会主义市场经济体制和高等教育改革，在客观上要求高校必须实行学分制。学分制可调动大学生学习的积极性，实现各类教育问的有效衔接和优势互补。     

学分制教学管理的探索与实施

21世纪我国高等教育改革的一个重要特征是普遍推行学分制。本文根据学分制教学管理的形式和特点，探讨了学分制教学管理的机制和模式，提出了学分制教学管理实施的原则和方法。     

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.

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-
