政府引导 企业参与 市场运作 群众受益——云南省丽江市古城区束河古镇建设发展纪实

束河古镇位于云南省丽江古城西北4公里处,是纳西族先民在丽江坝子中最早的聚居地之一。自明代以来,束河古镇逐步成为茶马古道上的重镇和纳西文化交流中心。许多从事皮革加工和其他手工业的人云集束河,非常繁华热闹,束河皮匠“一根锥子走天下”,足迹远达西藏和印度。周边的宁蒗永宁等地还有束河皮匠发展起来的“皮匠村”。束河古镇是纳西族从农耕文明向商业文明过渡的活标本,是对外开放和马帮活动形成的集镇建设典范。拥有与全国重点文物保护单位白沙壁画同一时期的明代壁画、明代建筑大觉宫、清代建筑三圣宫等珍贵文物和建筑。它集纳西文化…

Nothing Like New: Our Post-Apocalyptic Imagination as Utopian Desire

Most apocalyptic films are considered dystopian based on their aesthetic terms, yet many of their narratives are structured in such a way to reveal our society's larger utopian desires—particularly in terms of our future relationship with nature, the role of the individual in society, and particular ideals of community life. This article traces several dominant themes found within this genre of cinema as related to contemporary urban design solutions and recent post-disaster strategies, in order to expose what collectively we may be hoping for, as well as still fear.     

电梯企业的生存与发展

随着21世纪我国经济持续发展,电梯行业新一轮竞争的到来,群雄并起、诸侯列国、谁主沉浮。电梯企业仿佛江河中的小舢板,在市场经济大潮中,如何将小舢板演变为大轮船,最后打造成一艘坚不可摧的航空母舰驶进太平洋,以适应全球经济一体化的市场需求,为什么有些企业在千变万化、激烈的市场竞争中脱颖而出,长久保持了企业可持续发展,而有些企业还未来得及咸鱼翻身却折戟沉沙、销声匿迹,最终被迫破产解体或被残酷的竞争淘汰出局。     

医院中央空调系统运行节能

中央空调是技术性要求较高．涉及面较广的大型耗能设备。近几年来．中央空调的使用日益广泛．其能耗所占社会总能耗的比例也日益增大。据有关资料显示．七十年代末,我国建筑能耗仅占总能耗的17．66％,低于欧美,前苏联等国家,而现在已接近全国总能耗的30％．基本与欧美等发达国家相同,增长速度很快。据专家推算．仅一座2万平方米的建筑．能耗最高和最低之比．每年运行费用就相差100多万元．节能潜力很大,因此研究中央空调节能技术意义巨大。     

我们的城市,我们的建筑,我们的空间

1.1987年10月下旬,我大学毕业经过一番辗转后从桂林来到南宁,那时已是秋天,朝阳路上依然绿树成荫,浓密的扁桃树在天空下犹如一片绿色的浮云,苍翠欲滴。走在街上,能明显感觉到     

我们的系我们的家

走进清华园二校门．右手一侧那栋古老的二层楼——“清华学堂”是我们建筑学人的家．是一个看似古老却充满活力的家。我在那里长大成人，度过了6年最多彩的青春年华．那真是快乐时光．既使自己一个人回顾那些趣味横生的段子．也总不由得笑出声来。当然．也曾有些很倒霉的事．但作为代价．却成为一生中最宝贵的“承受力”．换一个角度看也是受用不尽的。     

我们的住宅,我们的生活

从现代单元式住宅反观中国传统住宅, 两种住宅和两种生活有很大的不同。传统住宅有一些有趣的布局,传统生活中有一些有趣的情景是现代单元住宅所缺乏的。文章从几个片断进行探索,试图把两者进行一点结合,使一些传统的生活方式得以继承。     

Comparing computer run time of building simulation programs

This paper presents an approach for comparing the computer run time of building simulation programs. The computing run time of a simulation program depends on several key factors, including the calculation algorithm and modeling capabilities of the program, the run period, the simulation time step, the complexity of the energy models, the run control settings, and the software and hardware configurations of the computer used to run the simulation. To demonstrate this approach, we ran simulations for several representative DOE-2.1E and EnergyPlus energy models. We then compared and analyzed the computer run times of these energy models.     

The theoretical analysis of the filter run time

The article presents a number of formulas for relative volume concentrations of the suspension and sediment, head loss in a uniform medium obtained as a result of a strict decision of mathematical problems of filtration of a constant discharge with linear and nonlinear mass-exchange kinetics. The procedure of accurate computation of the relative filter run time based on indicated formulas on the basis of maximum admissible quality of water purification and head loss in the medium. Using numerous typical examples we investigated the impact of the initial concentration of the suspension and sorption properties of the filtration material on the time of the filter efficient performance.     

Laboratory investigation of polyethylene sheeting as a friction reducer in deep foundation

A testing program was undertaken in which the effectiveness of polyethylene sheeting in mitigating downdrag in cohesionless soils was investigated using a direct shear apparatus and a rod shear test. A large number of concrete blocks were prepared in the laboratory and furnished with various arrangements of polyethylene sheets. These arrangements included samples with one or two sheets with fixed or free boundary conditions. The concrete-polyethylene-soil samples were tested in the laboratory under different temperatures and shearing rates. Based on the parameters used in this investigation, the obtained results demonstrated that the polyethylene sheets can be used as a friction reducer in piles. Using single layer of polyethylene sheeting reduced the skin friction by 62–67% depending on the soil type. The best arrangement was found in the two free 0·15 mm polyethylene sheets. This setup increased the effectiveness of the sheets to 77%. Lubricating the two sheet arrangement with mineral oil improved the effectiveness to 98%. Considering the effect of the shearing rate and the temperature on the behaviour of the lubricated sheets, a formula is suggested     

Our New Environment and Our Old Universities

The image that most readily comes to mind in connection with the university and its attempts, in professional design schools, to comprehend and cope with the problems of the bio-social and physical environment, is that of the five blind men who discovered an elephant and respectively conceived it as very much like a tree, a rope, a wall, a fan and a spear.     

让建筑的未来植根于森林

现代木结构建筑通过对森林资源的长周期利用,延长了森林固碳时间,减少了碳排放.从建筑全寿命期的角度,木结构在取材、运输、建设、运行、维护和拆除等各个环节都具有显著的低碳环保优势.秉持可持续森林管理理念发展木结构,是对现有建筑形式的有益补充,可为建筑业实现碳中和作出贡献.
