分析了高压真空断路器“跳跃”的成因、类型及其危害,可在控制回路或断路器本体上采取防跳措施。综合继电保护装置中的防跳措施不能防止断路器第二类“跳跃”的发生。当与断路器本体防跳组合起来时,需解决组合防跳的寄生现象。文章给出了几种目前常用的防跳控制回路,探讨了其不足之处,并针对寄生现象,结合实际,给出了防跳控制回路的三种改进措施.  相似文献

本文通过泉州地区某单位控制楼的基础方案变更的实例,阐述不同型式的基础按变形协调原理共同工作的设计方法。原设计挖孔桩因渗水过大,孔壁稳定等原因无法实现。修改方案由柱下交梁基础、已成挖孔桩护壁侧阻与锚杆静压桩共同承担荷载。在变形协调的条件下,只需各承载构件引起的土体变形均控制在一定界限内,则总的沉降就一定能控制在该界限内。已建成的工程沉降观测结果较好地证实了这种设计处理方法的正确性。  相似文献

The Djoser funerary complex was meant to be a house for a god and a metaphor for the sky. Today, it is usually understood that this original work of classical architecture is a vacant house of stone “from which the gods have fled.”

This difference does not have to be understood as a further sign of an irrecoverable loss of meaning. It is a historical doubling of meaning, or a duplicity. This article explores the duplicity of meaning of the Djoser complex by comparing references to architecture in the Pyramid Texts with texts of contemporary criticism, in particular, “The Pit and the Pyramid” by Jacques Derrida.  相似文献

仲德崐:《中外建渤杂志每一期围绕一个城市做一个主题,以座谈的形式谈论城市、谈论建筑、谈论文化,我是受杂志社的委托来召开这次关于我们南京城市的论坛。今天我们论坛的主题是“山水城林,南京论建”,“建”非宝剑的“剑”,而是建设的“建”,如果是宝剑的“剑”,那么就有武林大会的意思了。我们请了南京各领域的专家,有规划方面、建筑方面、风景园林方面,还有一些不可缺少的文化人。我始终有一个观点,认为一个城市的建设绝对不仅仅是建设一个物质环境,而是一个文化的氛围。我记得沙里宁曾经讲过一句话,“让我看看你的城市,我就知道这个城市的人民在追求着什么”。  相似文献

Landscapes, tourism, and conservation   总被引:1,自引:0,他引:1  
One key aspect of global change is a decrease in ecological integrity as more and more landscapes are developed, leaving a mosaic of intact refuges and degraded patches that may not be sufficient for conserving biodiversity. While increases in human population and shifts in the distribution of people affect land use, the temporary movement of people can have major implications for conservation and biodiversity. Three examples are presented where recreation/tourism can enhance the conservation of land on a landscape scale, leading to habitat protection and biodiversity preservation: (1) Shorebirds often require a matrix of different habitat types during migratory stopovers, and ecotourism can serve as a catalyst for landscape scale protection of habitat. (2) Riparian habitats can serve as corridors to link diverse habitat patches, as well as serving as biodiversity hotspots. (3) Remediation and rehabilitation of contaminated lands, such as those of the US Department of Energy, aimed at developing recreational activities on the uncontaminated portions, can be the most economical form of re-development with no increase in human or ecological risk. Since large areas on many DOE sites have been undisturbed since the Second World War, when they were acquired, they contain unique or valuable ecosystems that serve an important role within their regional landscapes. In all three cases the judicious development of recreational/tourist interests can encourage both the conservation of habitats and the wise management of habitats on a landscape scale. While some species or habitats are too fragile for sustained tourism, many can be managed so that species, ecosystems and ecotourists flourish. By contributing to the economic base of regions, ecotourists/recreationists can influence the protection of land and biodiversity on a landscape scale, contributing to ecosystem management. The human dimensions of land preservation and biodiversity protection are key to long-term sustainability, and ecotourists/recreationists can be one management option.  相似文献

The author draws on his career by referring to (a) the type of knowledge which engineers acquire and lose over time, and (b) the importance of socio-economic and environmental aspects of civil engineering projects.
In Memories , he recalls particular incidents in thirty countries and being confronted by unfamiliar cultures, and follows two vital threads which are woven into his experience, namely human nature and mother nature.
Reflections , based upon adult education, reveal aspects of the psychological understanding of human nature and the importance of biological diversity. The author finds some areas of apparently unresolved conflict between civil engineering and the environment.
Finally, in Dreams , the author quotes a United Nations set of priorities which provide a satisfying guide to the broad view of world developments and which can help to show the importance of biological and cultural diversity.  相似文献
