我国物理教育研究的现象学进路

我国物理教育研究缘起于1978年以来提升物理教学质量以及物理教师培训的实践,并在发展中提出了建设"物理教育学"的构想.当前物理教学论发展中蕴含着现象学的意蕴,包括物理概念与规律的教学、物理科学方法教学,以及物理问题解决领域.现象学视域下"物理教育学"的内涵是自我教育、自主学习.走向物理教育学的现象学路径包括让物理教育学成为智慧之学,开展物理教学的微观历史研究,并开展物理学习研究.

高师物理教育专业物理课程师范化研究

高师物理教育专业的课程设置始终沿用着“综合大学物理专业的专业基础物理课程 教育类课程”的模式,这不利于师范院校学生的物理专业从教能力的提高.由于高师院校与综合大学的培养目标不同,在物理课程的教材与教法方面也应有所区别.物理教师除具备一般的教学能力外,还应具备与物理专业相关的专业从教能力.     

浅析如何做好初中物理演示实验

物理演示实验,是物理课堂教学的重要组成部分,是学生由表入里、由浅入深认识物理知识的重要领域,在物理教学中成份较重.因此,在初中物理教学中,一定要做好物理实验,给学生学习物理知识创造宽松愉悦的环境,培养学生主动获取物理知识的习惯和能力,促进科学品质和世界观的形成.

中学物理实验教学初探

物理是一门以观察和实验为基础的科学.物理规律的发现和物理理论的建立都必须以严格的物理实验为基础,并受到实验的检验.物理实验是人们研究物理学的重要方法.所谓物理实验就是人们根据研究的目的,利用科学仪器、设备,设法控制或模拟物理现象,排除次要因素,突出主要因素,研究物理的一种方法.在物理研究中物理实验可以为发现物理规律提供丰富的感性材料;可以检验物理理论、假说的正确性;还可以开拓物理学应用的新领域.在中学物理教学中更有其特有的作用首先它可以使学生获得丰富的感性认识,加深学生对物理概念、原理和定律的理解,激发学生学习物理学的兴趣;其次可以培养学生的观察和实验能力,发展学生的智力;再者可以使学生初步了解物理学的研究方法,培养学生实事求是的科学态度和遵守纪律、爱护仪器的优良品质.     

中专物理学习中数学知识运用的几点注记

物理学是一门用定量方法研究的学科.因此.它与数学的关系极为密切.这不仅因为数学是表达物理概念和物理规律最简洁、最准确的“语言”,而且利用数学还可以反映确切的定量关系.但数学知识也有负迁移作用.在理解物理概念或运用物理规律时,常常见到不顾物理对数学的制约.把物理问题当成纯数学问题看待.造成对计算结果物理意义的错误理解和对物理问题的错误解答.     

民族地区初中藏汉双语物理教学质量研究

藏族文化中的物理实例研究

藏族传统文化中包含许多物理思想,而物理教学过程中利用身边的物理现象和物理实例,可以激发学生对学习物理的兴趣,加深学生对物理概念的理解和物理原理的应用.新课程本着"从生活走向物理,从物理走向社会"的教学理念,以藏族传统文化背景下的藏区中学物理教学为例,分析和研究了将学生所熟悉的藏族格言文化和民俗文化中的物理实例和物理原理如何切实有效地引入到物理教学中,以提高民族中学物理教学质量.     

基于隐喻认知的物理概念教学

从认知角度探讨了隐喻的认知功能,提出物理概念教学中隐喻构建的策略.隐喻为认知者理解物理概念提供了新思路,同时也为教师把隐喻应用于物理概念教学提供了新方法.物理概念教学中隐喻构建的关键,在于把握认知者所熟悉的事物与物理研究对象双方在特征属性、研究方法以及物理内涵方面的关联.     

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
