房地产开发生态足迹模型构建及实证分析

基于生态足迹理论与分析方法,提出了房地产开发生态足迹和房地产开发生态承载力的概念,构建了房地产开发生态足迹及房地产开发生态承载力的简化计算模型,并以2005年南京市住宅开发为例开展了实证分析.研究结果表明,2005年南京市住宅开发处于严重的生态赤字和不可持续状态,其生态足迹约为生态承载力的116倍,应通过适当提高住宅容积率、建设生态住宅、提高建筑材料利用效率、发展循环经济等手段以降低住宅开发的生态赤字,促进住宅开发乃至房地产业的可持续发展.     

基于生态足迹的住宅项目可持续建设评价

目的对住宅项目进行可持续建设评价,为住宅项目前期策划乃至后评价提供必要依据。方法将生态足迹理论与能值分析方法相结合,并应用于住宅项目可持续建设评价中,通过构建住宅项目生态足迹评价模型,来判断住宅项目的生态盈余或亏损,评价项目对当地的生态影响及项目建设的可持续性,并以北京市某住宅项目为案例进行实证分析。结果案例所在区域的生态承载力明显大于项目建设所造成的生态足迹,生态盈余为12.2 hm~2,表明住宅项目的开发建设对当地生态环境压力较小,项目的开发建设在生态环境可持续发展上具有可行性。结论住宅项目的开发建设不可避免地会对当地环境造成一定的影响,利用住宅项目生态足迹模型可以有效评价这种影响的大小,生态足迹模型对于判别住宅项目建设可持续性具有较强的实用性。

专家访谈——生态住宅：科技渗透于细节之中

江亿教授现任清华大学建筑学院副院长、建筑技术科学系主任,还是清华同方总工、北京市政府顾问,城市集中供热中国暖通空调委员会委员以及英国J.of CIBS杂志编委。江教授同时担任工商联住宅产业商会的委员,也正是这一商会与中国太平洋经济合作理事会(PECC)中国委员会工商委员会联合发起“亚太村”生态住宅这一生态住宅品牌建设项目。 在电话采访中,江教授谈到了我国目前生态住宅的发展与外国的现实差距,谈到了目前存在的一些错误观点,还谈到了科技发展对生态住宅的影响。在江教授不多的话语中,记者分明能感受到他对现今生态住宅的“恨铁不成钢”,以及对其来来发展的殷切期望。

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
