长余辉绿色照明材料研究

介绍了一种特制的长余辉材料，它能吸收天然光和灯光，并贮存光能， 经延时后直接射出可见光。该材料不但可以吸收紫外线、紫色光、蓝光和绿光，而且无放射性，发光强度是以前磷光材料的１０ 倍以上，余辉时间为２４ 小时以上，寿命为１０ 年以上，可作为指示照明等用。     

时代精神与建筑传统

传统是一个长久不衰的话题，本文试从时代精神的角度来阐释传统的意义。对于传统的继承从本质上说就是对这种精神的继承，而不是对形体的单纯模仿。而对于当今的建筑师，除了要明白传统的本质意义外，最重要的是要能够把握这种精神并表达出来。     

Urban water and nutrient flows in Kumasi,Ghana

Material flow analysis was applied to model different scenarios which help better identify and quantify water supply and wastewater pollution problems in the city of Kumasi, Ghana. Results show that despite a relative abundance of water resources in the surrounding area of the city, drinking water consumption will remain at a low level (from 49 ± 4 l/cap/day in 2006 to 59 ± 5 l/cap/day in 2015). Changing sanitation practices to using more flush toilets will require significantly more water if these toilets are to be used adequately. The water–nutrient balance shows that total nitrogen (N) and phosphorus (P) outputs of the modelled area are 10 times higher than system inputs, most of this being attributed to human wastes from sanitation. A number of possible measures to reduce nutrient flows into water bodies were identified and quantified, showing the usefulness of the applied model in providing estimates for municipal decision-makers.     

北方公共建筑供热节能空间探讨

通过对某办公大楼现有供热系统进行自动控制改造,并对其实测数据比较,得出改造后其白天工作时间内供热节能可达35％,如果夜晚休恩时间内采用防冻措施供热,能量节约效果更高的结论。     

漳州地下热水资源评价方法浅析

原《漳州地热详查报告》以开采模数法计算基岩裂隙热水允许开采量7598.2m3/d作为C级储量,《漳州盆地地下热水动态监测报告》以开采模数法加中温区试验推断法计算水温≥40℃基岩裂隙热水允许开采量5153.3m3/d,此二数值与实际开采量加基坑降水量之和对比分析,均偏小,以大井法计算水温≥50℃的孔隙热水允许开采量作为C级储量更为可靠,按水位降深5.45m计,并经垂向、侧向补给量保证验算修正后,允许开采量10208.97m3/d。     

浅谈企业施工定额的编制

随着我国工程量清单计价方法的步骤不断加快,作为施工企业,将面临着更为激烈的竞争与挑战,施工企业必须及早更新观念,提供竞争意识,在市场竞争中形成自己成熟有效的价格体系,才能在日趋激烈的市场竞争中处于不败之地.为此,本人根据实际经验,阐述了企业施工定额编制的意义以及施工企业定额编制的原则、依据及内容,对施工企业定额的编制提出了几点意见.

景观光环境规划设计方法初探

以“光”——这个独特同时又很重要的视角,探讨如何营造良好的景观光环境。目前对夜晚景观中灯光环境,社会及业内已逐渐关注,但对白天景观中自然光的研究国内外几乎空白。基于理论研究和工程实践,本文对景观规划设计中如何营造白昼时的光影、夜晚时的灯光氛围,以及在景区规划、景点设计、设施构筑和材料选取等具体过程中如何同时考虑昼和夜的理想效果而进行初步总结和探讨。
