对学生体质健康下降原因与对策的思考

近年来，我国学生体质健康状况不容乐观。认为不良的教育观念、学生的学习负担过重、学校体育的缺位、不良的生活方式、场地器材缺失等是导致我国学生体质健康水平下降的主要影响因素。为了提高学生体质健康水平，学校体育工作要从转变教育观念、调整指导思想，主要从学校体育的角度提出应对的策略与思考。     

对我校大学生体质健康现状检测分析与体育教学改革对策研究

根据《学生体质健康标准》实施办法的规定，对我校大学生进行体质健康检测，得到目前我校两届大学生体质健康的总体水平指标，并找出与体育教学密切相关的体质健康指标作为体育教学改革的切人点，应以体质健康教育为中心，加强体育课教学目标、教学组织形式、教学内容和实际操作等方面进行深入改革，开展体育与健康教育，建立以增强大学生体质为目标的多元体育教学体系．     

中学生体质与家庭社会经济因素的调查与思考

随着我国学校体育改革的不断深入，针对我国学生体质较差的问题，教育部、国家体育总局联合颁布了《学生体质健康标准》方案。新标准从身体形态、身体机能和身体素质等方面，综合评定学生的体质健康状况。新的体质健康标准围绕着“增强学生体质”这一中心任务，对学校体育领域和学校工作者都提出了更高的要求。本文从中学生体质与家庭社会经济因素之间关系的角度论述了我国教育方针求学生德、智、体、美全面发展，学校体育是学校教育的重要组成部分，是一种有目的、有针对性、事半功倍的发展学生体质的途径。     

浅谈德育教育与体育教学

我国学校体育教育的总目标是：“增强学生体质,促进学生身心的和谐发展,培养学生体育能力和良好思想品德,使其成为具有现代精神的德、智、体、美全面发展的社会主义建设者”在为实现我国学校体育教育总目标的过程中,体育教学不仅担负着传授体育知识、技术、技能、增强学生体质的任务,而且还担负着培养学生的道德品质和对其进行思想政治教育的重任。     

中国高校体育发展的障碍

体育教育是我国高校与社会发展最直接、最密切的部分，加快高校体育教育的改革和发展，关系到学生体质、健康水平，关系到学生终身接受教育和学习、生存能力的实践。当前高校体育发展滞后，与中小学体育薄弱，高校体育教学现状，体育运动竞技水平低，体育实践能力差、体育设施落后等严重阻碍了中国高校体育教育的发展。

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.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

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.

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-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that
