教学投入与教学适度

教学投入是教师应有的教学态度，而教学适度则是教师在某阶段的教学总体要求与某个特定“班情”具体结合的教学效果。本文着重谈教师在课堂上想取得预期效果，达到教学适度在注意的几个方面：教师在课堂上的作用是助学，不是替学；教学原则应是要站在学生水平上思考问题；教学战术灵活多样，但必须留有余地，引导学生自己思考，解决问题。     

教学基点转换中的微格教学

微格教学是教师教学技能培训的一种可行方式，随着教学基点由传授知识向培养学生完整人格和创新精神的转换，以及对教师专业素养认识的深化，微格教学必须完善自己的教学技能培训体系，必须使自己的组织实施向真实的教学情境延伸。

分层教学能够充分调动各个层面学生的学习积极性,培养数学兴趣,是提高大学数学教学质量的一个积极措施.本文对数学教学中的分层教学进行了分析和思考,从四个方面探讨了分层教学的途径.     

“机械效率”教学案例及教学反思

针对教师教学反思中的常见问题，以初中物理“机械效率”概念教学为例，从对教学目标的思考和概念教学的规律两个方面，对如何进行教学反思提出了自己的观点。即对教学内容的分析是反思的基础，教学内容是反思的落脚点，教学规律是教学反思的框架。     

浅谈启发式教学中的情感教学与问题教学

本文分别论述了作为启发式教学重要因素的情感教学和问题教学的涵义、形成的依据或分类与在教学中如何体现的方式等，并进而指出这两者的结合就是启发式教学过程的“动机”与“活动”的环节，在教学中抓好这两个环节，对保证启发式的实现与教学质量的提高有重要的意义。     

网络教学中的教学设计探讨

随着多媒体网络技术的迅速发展,网络教学已经成为现代教育的重要手段。许多中职学校以大力发展网络教学作为提高教学质量的突破口,而加强教学设计是发挥网络教学的优势,提高教学水平的重要因素。作者探讨了中职学校的计算机学科网络教学的特点,网络教学的设计和网络教学的评价。     

视频教学在肩周炎推拿教学中的应用

视频教学作为一种有效的辅助教学手段在医学教学中得到了相当广泛的应用。本文通过分析肩周炎推拿教学的特点,比较传统教学和视频教学优劣势,在教学的实践中探索和总结视频教学在肩周炎推拿教学中的应用优势,并且提出教学视频课件的具体制作要求,提出视频教学与传统推拿教学紧密结合的必要性。     

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.     

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     

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
