广西普通中学体育整体优化改革实验研究

探索不同的学校体育模式,为落实每天一小时体育锻炼,根据学校自身的条件和特点,通过实验实施“234”含3+1体育作业.“234”体育模式:即每周2节体育活动,每天做3操:早操、大课间操(系列课间操、健力课间操、武术操)、眼保健操.3+1体育作业:学生每周自觉进行不少于3次晨炼,参加一次社区体育活动.实验结果表明,学生对新模式下的体育课、课间锻炼、课外活动等方面态度有明显变化.喜爱运动的学生参与率逐步提高.学生参与性的增加,促使学生的体质得到增强,发病率下降,上课时精神注意力更为集中,促进学生文化课学习效果的提高.     

如何在中学开发自编操课程资源

新世纪,随着体育课程改革的不断深入,学校体育中的各个层面也都进行了一系列的发展与变革,课外体育也得到的足够的重视。作为多年来我们一直在课间做广播体操的体育活动模式受到巨大的冲击与挑战,仅仅靠一套广播体操无法调动学生参加活动的积极性,由此提出“大课间”这一新的课间体育活动模式。无论如何变化,由于课间活动的时间有限,学校的各方面体育设施的限制,不是任何项目都适合在课间完成,作为占学校场地器材少,容易调动全体学生活动的自编操显示了独特的魅力,在课间体育活动中占主导地位,因此,充分发挥自编操的功能就显得尤为重要。     

义务教育阶段学校体育整体设计探索与实践

坚持"健康第一"的指导思想,根据学生生理、心理特点,遵循体育教育规律,对体育课堂教学、课间操、大课间、综合性体育竞赛、单项竞赛、特色活动、业余训练等学校体育活动,进行整体规划和设计,以提升学生体育学习和活动的质量和效益,提高"增强体质、提升素质"目标的达成度。     

关于开展课间体育活动的思考

课间体育活动是国家有关“每天运动1h”的指导性文件中的一个重要体现形式之一，我国各级学校尤其是广大中小学校在此方面进行了坚决的贯彻和落实。课间活动得到了大面积的推广，面对发展形势，仍然需要对其在具体实施过程中所面临的问题进行有效的总结和思考，力求探索出一条适合地方特色的课间体育活动实施路径。     

小学生落实“每天锻炼1小时”对体质健康的影响

目的：研究“每天锻炼1小时”和“大课间”对学生体质健康的影响。方法：对2008年入学6个班的新生,随机分为“实验班”和“对照班”,分别实施“每天锻炼1小时”和“大课间”体育锻炼。结果：2011年“实验班”的各项体质健康测试指标均比2008的指标有了非常显著性提高P〈0．01）,甚至是极显著性提高（P〈0．001）,也有多项指标比同期的“对照班”显著性提高（P〈O．05）甚至是非常显著性提高（P〈0．01）和极显著性提高（P〈0．001）;而“对照班”的指标虽有所提高,但没有统计学差异。结论：在体质健康水平方面,“实验班”比“对照班”具有更全面深刻的影响和显著性的提高。建议：教育行政部门、学校领导重视落实“每天锻炼一小时”的阳光体育运动,将对学生体质健康水平的提高大有益处。

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-
