居住区意象空间研究及应用

在回顾意象空间研究发展历史的基础上,整理并归纳了意象空间的研究内容、研究方法以及应用等方面的特点.将意象空间引入居住区的空间研究中,以张掖市新乐小区为例,对居民构想图的类型、构成要素及这两者的差异性特征,与城市意象空间的关系,以及意象空间研究在居住区规划中的应用进行了初步探讨.结果表明,该居住区居民构想图可分为3类,即序列型地图、空间型地图和单体型地图;居民性别、年龄和学历的不同均对居民构想图的级别有影响;居民意象空间的构成要素与传统的5要素一致,标志物和道路是居住区意象空间的主要因子,构成要素存在着居民属性差异.居住区意象空间研究为规划设计的构思、重点的把握以及特色环境的营造提供了可靠的依据,是促进规划公众参与的有效途径之一.     

城市现代居住区植物景观设计初探

1.前言居住区绿化是城市绿化的重要组成部分,最接近居民,与居民日常生活关系最为密切,它对提高居民生活环境质量,增进居民的身心健康至关重要。居住区的绿化水平,是体现城市现代化的一个重要标志。居住区绿地在城市园林绿地系统中分布最广,是普遍绿化的重要方面,是城市生态系统中重要的一环。随着社会的进步,生活方式的变化,人们也渴望有一个自然的空间接纳他们的生活和情趣。因此从发挥居住区绿化最佳的生态效益、改善城市小气候和居民的心理需求出发,,居住区绿化应以植物造景为主,由此所创造的环境氛围才充满生机活力和具生活气息,能做到景为人用。完美的植物景观,必须具备科学性与艺术性两方面的高度统一。既要满足植物与环境的统一,又要通过艺术构图原理体现出植物个体与群体的形式美,及人们在欣赏时的意境美。可以说,植物景观和人的需求完美结合是植物造景的最高境界。

基于生活空间质量的居住区规划与调控研究

居住区是城市生活空间的主要载体,居住区规划和建设水平的好坏直接影响着居民的人居环境和生活质量.因此,应该高度重视居住区的规划设计,从规划理念、规划方案、建设实施到运行管理,都必须有全新的思路和规划理念.而规划是龙头,居住区规划的好坏直接影响到居民的生活空间质量和人居环境的改善.因此,在居住区的规划设计中应该以打造良好生态环境、保证生活空间质量为原则,注重生态环境与开敞空间的有机融合、注重功能分区与多种空间的优化组合、注重安全防卫和邻里活动空间的合理设置、注重服务设施的完善与生活空间的综合利用,充分体现对人的关怀,坚持以人为本,大处着眼,整体设计,不断优化和改善人居环境.     

基于环境质量和环境负荷的可持续的居住区环境评价体系（Ⅰ）——居住环境质量

居住环境是提高生活质量的一个重要因素，也是经济、文化和社会等社会活动的一个重要支撑．然而，改善居住环境质量也一直在增加能源消耗和废气污染．文中同时考虑居住区的环境质量（Q）和居住区环境负荷（L），建立了系统化的方法来评价可持续居住区环境．Q部分是构建安全、健康、舒适、便利和社区性的人居环境；L部分是环境对居住和社区生命周期的影响．文中选择中国发展最快的、并给其他城市地区带来巨大影响的长江三角洲地区作为研究对象，来评价居住区的环境质量．作为该研究的第一部分，文中给出了在杭州和上海进行的针对居住环境质量的问卷调查结果，分析了人们对居住环境的满意度．在后续的研究中，笔者将进一步研究居住区环境负荷（L）的指标部分以及权重的确定．希望该研究成果能够为中国城市人居环境的可持续发展和质量改善作出贡献．     

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
