在不降低照明标准、提高照明质量的前提下,对城市道路照明采取节能措施很有必要。该文对城市道路照明从采用优质高效的照明装置(电子节能灯、高压钠灯、金卤灯和高效灯具以及电子镇流器);采用照明专用变压器和三相四线式配线方式;采用优化道路照明的控制系统(如微电脑智能控制器、对道路照明进行分组控制、使用道路照明微机监控系统)等方面进行探讨来挖掘道路照明节能潜力,最终达到按需照明。 相似文献

LED作为照明光源正被大量应用到建筑物外观照明之中,而照明与建筑的一体化设计也倍受关注,因此LED建筑化照明正成为夜景照明的应用趋势。而建筑外立面的材料和构造形式的最新发展也对LED建筑化照明提出了更多的要求。本文对于当代常用建筑外立面材料及其构造方式进行了分析,并探讨了应用于不同形式建筑外立面的LED建筑化照明方式。 相似文献

Copper sulphate, added at the surface, was retained in the epilimnion of a stratified tropical reservoir. For 12 days after the addition, most of the copper was associated with the soluble fraction (MW > 50,000). Later the low molecular weight fraction (MW < 50,000) dominated and persisted for more than 19 days. There was an immediate decline in algal density after copper addition, followed by an increase in numbers of the more copper-tolerant chlorophyte species. Zooplankton (and other aquatic fauna) were also affected by the copper treatment. Two forms of the rotifer Brachionus calyciflorous recovered first, followed by Hexarthra mira, Copepoda and Cladocera. Growth of cyanobacteria was suppressed in the short term, but any possible long term effects of copper were masked by flow induced rapid destratification which interrupted and re-set algal succession. It is concluded that copper treatment is not an effective control of cyanobacterial growth under the seasonal flow regime to which the Solomon Dam is subjected. 相似文献

A model for transforming a non planar graph, presenting the interrelations interrelations required in the adjacency matrix, into a planar one, was developed. This is achieved through cancelling some of the links in the graph. The algorithm is based on trying to minimize two factors: the number of cancelled links and their weight. The planar graph obtained is unfolded to get a graph drawn without crossing links. A graph dual to this unfolded planar graph can be considered as a schematic layout. The suggested approach to the layout problem is demonstrated through some case studies. 相似文献

Building ventilation is affected not only by the steady mean effect of air pressures and temperatures around and within the building, but also by the turbulent nature of wind causing a diffusion of air through openings and cracks in the building envelope.The ventilation of an enclosure with a single opening subjected to a turbulent impinging airstream is studied and simple theoretical models are derived to assist in understanding the physical phenomena causing airflow through the opening. These are compared with the results of experiments on a large scale model. The need for further work on this problem is stated. 相似文献
