怎样利用中学地理与相关学科的联系深化教育

<正> 中学地理与中学许多学科有广角、密切的联系(以下简称“联系”),在教学中注意并善于科学、合理地利用这些联系,对提高中学的教育质量有着很重要的意义、如何充分发挥中学地理的这种特殊职能,更好地深化中学教育,必须注意以下几点:1 找出“联系”点首先要钻深钻透中学地理教学大纲和教材,找出与其它学科有联系的地方,在教材中相应的地方作下标志;然后在其它学科的教材中找出与本学科有联系的地方,制卡记下。     

新时代的中国—东盟相处之道

中国与东盟国家比邻而居,山水相连,有着割舍不断的天然联系。东盟是东南亚国家的联合体,有了东盟,中国与东南亚各国的关系就有了"双轨":一是与东盟各国的双边关系,二是与东盟整体的关系。二者既有区别,也有联系,定位和处理得好,对发展双方的关系至关重要。二战后,中国、东南亚国家以及双方的关系都经历了转折性变化。     

科学与技术的辩证统一

科学与技术,是两个不同的概念。二者既有区别又有联系,是辩证的统一。只有弄清科学与技术的辩证统一关系,才能克服片面强调技术而忽视科学或者片面强调科学而忽视技术这两种错误倾向,使二者协调发展。     

关于科技发展规律的几点认识

科学,技术和工程是人类在认识和改造自然的伟大实践中获得的丰厚知识财富。它们分别对应于认识自然、改造自然的不同环节,因此,彼此之间有区别,更有联系。科学是认识自然现象、探索物质运动的客观规律所形成的基本理论、概念或原理:技术是运用科学理论,为提高效率、节约资源和开辟新生产领域而发展的方法、手段;工程是综合运用科学技术和经验,在生产实践中产生的设计、工艺、流程、装备和质量控制等。随着当代科学技术和生产实践活动的发展,三者之间的联系越来越密切。科学向技术、工程的转化和渗透更加快速、广泛,工程技术对科学进步的推动作     

躁动中的沉思—第六届全国科学哲学会议述要

7月10日,来自全国各地的70多名代表汇聚河南新乡召开第六届全国科学哲学大全。上届年会是1987年开的。本届年会的主要目的就是对6年来学术成果和研究队伍的状况作一次检阅。哲学和科学自古以来就存在着紧密的联系。在亚里士多德身上,哲学家和科学家的角色融为一体;爱因斯坦既是伟大的科学家,也是伟大的思想家和哲学家。如果说哲学是人类知识最高殿堂的话,那么自牛顿以后两百多年间,科学就是堂主。由于科学和科学应用的巨大成果,人们相信,科学和科学方法是获取知识的最可靠来源,靠着确凿无疑的知识的不断积累,人类最终将对自然规律和社会规律作出准确无误的描述和把握。然而,本世纪量子力学和相对论对牛顿体系的革命,把这种传统的科学观及其科学的世界图景冲得支离破碎,于是,围绕着科学与非科学的划界,理论与观察的关系。科学进步的模型等问题,涌现出逻辑实证主义,波普尔的证伪主义,历史学派,科学实在论,直到最近的后现代主义的科学哲学诸多流派。尽管它们在许多问题上存     

科学和技术:相互转化的史实和机制

一、科学和技术相互转化的历史事实 纵观近代以来科学和技术的发展历史,不难看到,任何科学进步都有它的赖以发展的技术基础、前提和手段,都有着获得进化动力的社会技术需要和刺激;另一方面,历史上任何新技术的产生、每次技术革命都有着或大或小、直接、间接的科学理论准备。科学和技术之间的相互联系是毋庸置疑的。但这种联系并不是一成不变的。如果我们考察近代自然科学产生以来,科学技术的历史发展,就可以发现它们的相互关系明显地经历了三个阶段的微妙变化。 (1)近代自然科学前期(1543—1788)与第一次技术革命(1764—1828) 近代自然科学…     

交叉科学方法初探

自本世纪三十年代后,科学的发展出现了一种独特的现象——不仅每一科学领域内部各学科之间的联系、渗透、结合等相互作用空前加强了,而且不同科学领域之间的联系、渗透、结合等相互作用也在加强。这种独特现象主要表现在各层次、各级别的交叉学科蜂涌出现和     

不妨给材料做点文章

“材料引起学习，材料引起活动。”材料是学生解决科学问题、获得科学知识、提高探究能力的基本载体，是学生感受科学与生活的联系，体验科学价值的重要资源。选择有结构的材料供学生探究活动，是提高科学探究活动效率的前提。所谓有结构的材料就是教师经过精心设计的典型教学材料的组合。这种材料的组合，既要揭示教学内容有关的一系列现象，体现教材的科学性．

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.     

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
