通过对屋顶花园在城市建设应用中的价值工程分析,提出屋顶花园是城市建设生态化、人性化发展的必然结果。屋顶花园不仅可以净化空气、降温隔热、保护屋顶,还开辟了绿色空间、美化了环境、改善了城市气候环境、增强了城市立体景观。屋顶花园在城市建设过程中使自然生态环境与城市总体环境达到和谐,是城市文明与文化生活环境的完美和谐。  相似文献

近年来,城市建设取得了突飞猛进的发展,城市的发展对生态环境提出了更高的要求,而绿化是改善环境质量,美化城市的量重要途径。但增加绿地面积需要占用土地.屋顶绿化可节约用地,又可改善环境.根据屋顶绿化的特点,文中着重阐述屋顶绿化植物的配置形式和屋面设计施工中应解决的几方面特殊技术问题,为更好建设屋顶花园,提高城市的绿化覆盖率,改善城市生态环境提供参考。  相似文献

我国大中城市的土地资源已是“寸土寸金”,可以用于绿化的土地面积越来越少。为了提高城市的绿化覆盖率、改善生态环境、美化城市景观,在商用、住宅等建筑上实施屋顶花园是最有效的途径之一。但是屋顶花园是是以建筑物顶部平台为依托,进行蓄水、覆土并营造园林景观的一种空间绿化美化形式,其涉及建筑、农林和园艺等专业学科,是个系统工程,必须从设计、选材、施工和管理维护等方面进行综合研究和处理。  相似文献

所谓城市高楼的立体绿化,就是把高楼的四周上下全面绿化起来,上有屋顶花园、下有绿草地、四周墙壁有垂直绿化,以增加城市的绿化面积,削弱大厦与大厦之间的相互热辐射.  相似文献

旧城商业改造往往面临用地紧张、停车位不足和新建筑与旧城空间结构易脱离等问题。在东莞E时代广场设计中,建筑师首先将停车与货车车流引入地下(货物通过货梯到达各层),将基地设置为全步行环境。同时将建筑各向开口朝向周边旧城街道,延续了旧城空间交通结构,并在三层屋顶设置屋顶花园,利用大台阶将屋顶花园与街道相连接,将人流引向二、三层,充分发挥各层商业潜力,屋顶花园与基地中心小广场一起构成立体化的绿化景观,还绿地于城市,创造于舒适宜人的绿色购物休闪环境。本研究结合这一具体建筑设计,探讨立体交通、空间对位和绿色共享空间等旧城商业改造中具有普遍意义的手法。  相似文献

浅析屋顶花园防水施工问题   总被引:1,自引:0,他引:1  
屋顶花园降温隔热效果优良,能够美化环境、净化空气、改善局部小气候,能够丰富城市的俯仰景观,能够补偿建筑物占用的绿化地面,大大提高了城市的绿化覆盖率,是一种值得大力推广的屋面形式。其防水处理的成败直接影响屋顶花园的使用效果及建筑物的安全,一旦发现漏水,就得部分或全部返工。所以防水层的处理是屋顶花园的技术关键,也是人们最为关注的问题。  相似文献

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.  相似文献

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.  相似文献

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。  相似文献

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.  相似文献

In the 19th century the society was controlled by men, and women were just appendants of them, they had not any rights and freedom. But Jane was an exception, she showed some characteristics of early feminist. Jane showed her characteristics of feminism in three aspects: rebellion, equality, and independence. These characteristics were helpful to her success, and feminism is the only way out for women of that time.  相似文献

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-  相似文献

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-  相似文献

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  相似文献

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  相似文献

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of  相似文献
