| 1 | The common language of space:a way of looking at the social,economic and environmental functioning of cities on a common basis显示文摘This paper proposes that in addition to urban research which seeks to provide answers to policy questions, there is also a need for research which directly addresses the physical and spatial complexity of the built environment itself, and explores any effects it may in itself have on the functioning of the urban system. This type of research reflects the questions architects and urban designers typically ask, rather than those that preoccupy planners. For such research to be effective, the physical complexity variable must be controlled at the level at which real design decisions are made. “Space syntax” research attempts to do this by treating built environments as systems of space, analysing them “configurationally”, and trying to bring to light their underlying patterns and structures. Results from space syntax research into many aspects of urban space and how it works show a consistency which suggests that analysing spacial structure can be a general means of investigating the structure and function of cities. It may, in effect, be the common language of the city. | Bill Hillier Bartlett School of Graduate Studies, University College London, Gower Street, London WC1E 6BT, U.K. E\|mail:b.hillier@ucl.ac.uk | 1999 | Journal of Environmental Sciences1999,11,3: | 18 |
| 2 | COMPOSITE SOFT SWITCHING CONFIGURATION FOR INVERTERS USING BRIDGE LEG MODULES显示文摘The use of either lossless snubbers or resonant zero voltage switching (ZVS) and zero current switching (ZCS) techniques can increase efficiency and reduce electromagnetic inter ference (EMI) and noise of industrial power equipment at high switching frequencies. This paper presents an adaptive composite soft switching configuration which combines snubber functions and resonant ZCS circuits for switches in inverters using power bridge leg modules. Simulation and experimental results are included. | He Xiangning Yang Yuwen (Dept of Electrical Eng., Zhejiang University, Hangzhou 310027)Kuang Sheng(Department of Engineering, University of Cambridge, Cambridge, U.K.)Barry W.

| 3 | 用数值模拟法估量井筒保安矿柱稳定性的案例研究显示文摘在印度拉贾斯坦邦乌代布尔的扎瓦尔地区,莫奇亚铅锌矿是最古老的生产矿山。为了预测此矿山辅助井井筒保安矿柱的稳定性,采用伪三维边界元技术和二维有限元技术做了数值模拟。以位移不连续法为依据的伪三维边界元程序被用来模拟矿柱和矿房。由于这个模型不能估算封闭应力的量值,矿柱也用二维有限元法模拟。用沿脉平巷和辅助井井筒保安矿柱内岩石的渐进断裂以及应力计的观测成果,对该模型做了校准。由这两种技术获得的成果,使得有可能靠分析应力的增长来预测辅助井井筒保安矿柱的稳定性。根据这项研究得出的结论是:这两种数值技术的综合应用,为更逼真地预测矿山巷道周围岩体的受力现象缔造了适宜的工具。 | U.K.辛格 D.G.拉奥 宋彦琦 | 1995 | 国外金属矿山1995,20,7: | 5 |
| 4 | 与花岗岩有关的成矿流体与成矿金属研究显示文摘虽然分异结晶和热重力扩散对花岗质岩浆结晶过程中成矿元素的相对富集有重要的影响,但在此过程中富水流体相的分离却显得更加重要,温度、压力、流体成分及水的绝对含量决定着亲花岗岩类元亲从熔浆中分离出来的量.流体中成矿元素主要以Cl ̄-、F ̄-、OH ̄-、HS ̄-等的络合物形式迁移,而其沉淀环境则介于岩石缓冲及流体缓冲条件之间。 | Wang Cansheng(Dept.of Geology,University of Southampton,Southampton SO9 5NH,U.K.)Xia Weihua(China University of Geosciences,Wuhan,430074) | 1994 | 地学前缘1994,1,3: | 4 |
| 5 | A general finite element model for numerical simulation of structure dynamics显示文摘A finite element model used to simulate the dynamics with continuum and discontinuum is presented. This new approach is conducted by constructing the general contact model. The conventional discrete element is treated as a standard finite element with one node in this new method. The one-node element has the same features as other finite elements, such as element stress and strain. Thus, a general finite element model that is consistent with the existed finite element model is set up. This new model is simple in mathematical concept and is straightforward to be combined into the existing standard finite element code. Numerical example demonstrates that this new approach is more effective to perform the dynamic process analysis in which the interactions among a large number of discrete bodies and continuum objects are included. | WANG Fujun1, LI Yaojun1, Han K.2 & Feng Y.T.2 1.

| 6 | Fracture Mechanics,Crack Propagation and Microhardness Studies on Flux Grown ErAlO_3 Single Crystals显示文摘Results on fracture mechanics and crack propagation have been obtained, making use of Vickers microhardness studies on two different crystallographic planes [(110) and (001)] of flux grown erbium aluminate crystals in the load ranging from 10-100 g. The variation of microhardness with load which is best explained by Hays and Kendall’s law leads to the load independent values of hardness. Classification of cracks is dealt with and it is reported that the transition from Palmqvist to median types of cracks occurs at higher loads. The values of fracture toughness (K_C), and brittleness index (B_i) are calculated using median types of cracks. | K.K.Bamzai and P.N.Kotru (Department of Physics, University of Jammu, Jammu 180006, India) B.M Wanklyn (Department of Physics, Clarendon Laboratory, Oxford University, Oxford OX1 3PU, U.K.) | 2000 | Journal of Materials Science & Technology2000,16,4: | 3 |
| 7 | 自然环境、健康和行动障碍者--丹麦行动障碍者绿色户外实验室项目前期探索性研究简述显示文摘研究表明,自然是人类重要的健康资源,而行动障碍者因自身活动能力所限,接触自然的机会少,以致难以充分享受自然赋予的健康福利。本文描述了丹麦行动障碍者绿色户外实验室项目前期探索性研究的主要成果,旨在通过设计和利用自然环境提高行动障碍者的健康水平。结果表明,残疾人群体对在自然中的活动有着浓厚的兴趣,尤其偏爱自然环境。同时,自然环境对他们的机体、心理和社交健康均具有积极影响,而结构性障碍、个人内在障碍和人际交往障碍限制了他们对自然环境的利用。在自然中提供无障碍路径、无障碍设施以及清晰并及时更新的信息,有助于残疾人更好地利用自然环境。根据前期探索性研究结果,将设计、建造一个户外实验室,用于开展更全面的研究,具体涉及基于证据的健康设计的发展、项目的实际效果测试与评价、基于自然的活动和在自然中开展的康复项目等方面。 | 张高超 | 2018 | 残疾人研究2018,0,4: | 2 |
| 8 | SIMULATING REGIONAL SYSTEMS: A SYSTEM DYNAMICS APPROACH显示文摘System dynamics is a rigorous method for qualitative description,exploration and analysis of complex systems in terms of their processes, information flows, orgaruzational boundaries and strategies, which facilitates quantitative modelling and analysis for design of system structure and the improvement of system behaviour. It can be applied to the study of a wide range of systems, and its ability to describe socio-economic characteristics and behaviour makes it suitable for the analysis of the regional development process. Three examples of System Dynamics models are reviewd to demonstrate the suitability of the method for regional analysis, and on the basis of this review the potential use of system dynamics models in China is discussed. | Colllin Lee(School of the Built Environment, Coventry University, Coventry, U.K.)Guo Rongxing (Beijing Graduate School of CUMT, and Paking University, Beijing 100871 People’s Republic of China ) | 1996 | Journal of Geographical Sciences1996,6,2: | 2 |

| 18 | ADVANCED QUALITY CONCEPTS AND COMPOSITE RELIABILITY THROUGH STATISTICALPROCESS CONTROL显示文摘The physical properties of thermosetting resins and resin based composites may be influenced by changes in any one of the mang formulating or process related variables involved in their manufacture. When resins and composite materials are required to perform in aggressive environments, reliable and predicable performance is essential and therefore these materials must be prepared and tested in accorkance with a strictquality plan. This paper outlines the elements of statistical process control (S.P.C.)as it may be applied to non-metallic materials and discusses the concept of Capability Index (Cp). | D.
