混凝土施工机械可持续发展的一些技术措施

随着我国基础建设形势的蓬勃展开和西部开发战略的推行,我国的建设施工机械获得了一个大好发展机遇。同时国家也加强了在发展中对保护生态环境的控制力度。例如对发动机废气排放的控制,对施工机械的作业噪声控制等。施工机械的使用不能损害人类的生存环境,这种要求已是必然趋势。这就促使我们提高和改善混凝土施工机械的技术品质。如果只注重降低成本,而不同时注重自己的产品与时俱进,最终也将影响到产品本身的前途。我们认为,目前混凝土施工机械可持续发展技术主要应致力于:①节约能源;②减少污染;③改进性能;④提高效率。本文主要就节约能…

What can be taught in architectural design? — <Emphasis Type="Italic">parti,poché</Emphasis>, and felt qualities

This essay begins with a reflection on what has been taught in architectural design since the turn of the twentieth century. I shall trace back to the two disciplinary foundations of the French École des Beaux-Arts — parti and poché — in the education of an architect in the eighteenth and nineteenth centuries. I shall then attempt to superimpose parti and poché on a modern disciplinary framework, say that of mathematics, which leads to musings on a series of architectural problems that include pattern versus type, stability versus mobility, orthogonal versus oblique, confinement versus transparency, and aging versus metallic sheen. These paradoxes, I suggest, demand the education of an architect to address both the instrumental pattern of a building configuration and the ambient felt qualities of a room, rather than vision alone.

Spatial competition and regulatory change in the grain handling and transportation system in western Canada

The grain handling and transportation system (GHTS) has been a defining component of the western Canadian economy since the early part of the last century. Only two major railways serve the grain handling industry, so the potential for the exercise of market power in transportation appears to be significant. In fact, spatially oriented regulations applicable to railways exist in Canada to mitigate this, but to date they have not often been used by shippers. While the reasons for this are not completely clear, we suggest that the regulations are now inadequate for the current state of the GHTS. Using a unique data set from the year 2000, we assess the effect on the grain handling industry of modifications to these regulations, and find that significant gains for shippers from these modifications are possible. These gains are computed to be on the order of C$10–15 million per year for grain shippers alone. We would like to thank conference and presentation participants (Transportation Research Board, Canadian Agricultural Economics Society, University of British Columbia, University of Leeds and California State University, Long Beach) as well as the anonymous reviewers who commented on the earlier versions of this paper. We would also like to acknowledge support from the Saskatchewan Department of Highways.     

如何搞好实验室仪器设备的期间核查

根据GB/T 15481-2000 idt ISO/IEC 17025-1999<检测和校准实验室能力的通用要求>第5.6.3.3条<期间核查>的要求"应根据规定的程序和日程对参考标准,基准,传递标准或工作标准以及标准物质(参考物质)进行核查,以保持其标准状态的置信度".这就要求检测和校准实验室的仪器设备应建立期间核查的程序文件并实施,其目的是为了及时发现运行的仪器设备是否有问题,防止使用不符合技术规范要求的仪器设备,以及可以缩短失效后的追溯时间.
