人地关系理论的研究进展

人地关系和人地关系理论一直被认为是人文地理学研究的核心主题。随着社会的发展,人地关系理论在不断完善,新型人地关系理论不断出现且逐步形成理论体系。本文介绍了3种新型人地关系理论：人地关系危机论,人地关系调控论,人地关系目标论。

人地关系是地理学研究的核心,人地关系存在于地域系统之中对人地关系地域系统的基本类型作进一步扩展的尝试,以期对人地关系的地域系统类型有更全面的认识和了解。     

对人地关系中几个问题的探讨

从人地关系的界定、人地关系的哲学与伦理思辨、人地关系的属性、人地关系矛盾的表面和影响因素以及人地关系研究方法几方面对人地关系进行了初步的探讨。     

人地关系地域系统浅论

人地关系是地理学研究的核心，人地关系存在于地域系统之中对人地关系地域系统的基本类型作进一步扩展的尝试，以期对人地关系的地域系统类型有更全面的认识和了解。     

人地关系的协调及展望

人地关系研究是近代地理学发展的基础,本文从人地关系的含义和人地关系关系协调概念的含义出发,阐述协调人地关系的依据和原则,最后谈到我们时代面临的机遇与挑战,试图说明处在我们这个时代的人地关系的重要性。     

人地关系协调发展的途径探讨

人类文明是在人类认识、利用、改造和适应自然的过程中不断演进的。人地关系是人类生存与发展的基本关系。追求人地关系的和谐是实现社会经济持续稳定协调发展的基本原则和根本保证，也是人类文明的共同价值选择和最终归宿。如何实现人地关系的协调，则是当前人地关系研究中的核心所在。     

桂西地区人地关系类型划分及其特征研究——民族地区地质公园建设与旅游开发系列论文之二

人地关系分析是其他相关研究的基础,以桂西地区为例探讨基于聚类分析的人地关系特征定量研究方法:首先构建桂西地区人地关系评价指标体系;其次确定桂西地区各行政区划单元不同人地关系评价指标数值;第三,采用聚类分析法,将桂西地区划分为中心城市地区、旅游业发展较快的贫困地区、资源型工业(矿业、水电)地区、旅游业发展较好的少数民族聚居地区、较发达资源型工业(矿业)地区、欠发达农业地区6种人地关系类型.     

宁夏人地关系的历史演变及其特征

人地关系是人文地理学研究的核心问题，而位于半湿润向半干旱和干旱过渡地区的宁夏，长期以来一直是人地关系的敏感地区．从人地关系相互作用的主导因素、时空分布和作用方式等探讨了宁夏人地关系的历史演变及其表现特征，并对划分3个大演变阶段进行了分析，总结了宁夏人地关系演变中的敏感性、多民族的碰撞与融合，以及二元化地域结构等基本特点．     

人地关系的哲学思考

讨论了人地关系的哲学原理,认为单纯经验的人地关系研究在理论上是不完备的,缺乏基础理论。本文提出运用时间,空间,能量和事件这四要素对人地关系进行哲学思考与理论建构,以及提出人地关系的科学化问题。     

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
