管式电除尘器"伞形罩"结构特性研究

在高温、高湿窑炉烟气条件下,采用立式管式电除尘器“伞形罩”结构,能够解决其清灰不力、二次扬尘、除尘效率不稳定等问题。本研究了“伞形罩”结构的除尘机理及效率及清灰力度影响因素、抑制二次扬尘机制。研究结果表明,“伞形罩”结构除尘效率因集尘表面积的增加而提高;应用支铁框架式振打方式,振打强度明显加强;其分流机制能有效地抑制二次扬尘：从而为“伞形罩”结构的优化设计提供了依据。

Assessment of older drivers: relationships among on-road errors, medical conditions and test outcome

PROBLEM: It is essential that driver licensing authorities have a valid and reliable system for evaluating older drivers' continuing competency; road tests are usually required as part of such a system. This study sought to find information about the nature of driving errors made during license review tests, and about relationships between error type and test outcome for older drivers. METHOD: Data from licensing authority files from 533 road tests during a 12-month period were analyzed; medical and other referral information was included. Average driver age was 76 years. Performance scores were generated for intersection negotiation, lane changing, low speed manoeuvres, positioning and speed control, safety margin, and car control. RESULTS: Logistic regression analysis showed that test outcome was well predicted by a subset of driving performance scores; adding driver age to the model explained very little variance. Age alone was strongly associated with outcome. Relationships between referral information and test outcome are also reported. IMPACT: Results highlight several factors relevant to the development of more valid and reliable road tests for older drivers.     

长江流域生态环境的意义及生态功能区段的划分

中国加入WTO之后,中国经济进一步与国际市场接轨,融入世界经济体系,机遇和挑战同在。欧美各国近年大力推行的环境标志产品认证,对第三世界商品质量设置入关的环境门槛。长江产业带作为世界最大的内河产业带和制造业基地,现在世界通行的环境管理认证体系和环境标志产品的认证,对长江流域产业尤其是外贸出口产业有长远而深刻的影响。这种认证制度,一方面对我出口商品设置了新的障碍,另一方面又将环境保护压力直接施加到企业。重视流域生态环境将从政府行为、公民压力扩展到企业行动,由于流域生态环境的负荷愈来愈重,流域生态环境的自我调节和恢复功能大幅下降,引起了日益严重的流域性生态安全问题。根据长江流域生态环境特征、不同的生态功能及存在的主要生态安全问题,将长江流域划性生态安全问题。根据长江流域生态环境特征、不同的生态功能及存在的主要生态安全问题,将长江流域划分成以下五个不同的生态功能区段,即长江源地区、金少江段（直门达至宜宾）、长江上游段（宜宾至宜昌）、长江中游段（宜昌至湖口段）、长江下游段（湖口至入海口）。针对不同区段主要的生态安全问题,应因地制宜采取相应的防范和整治措施。为保护与恢复生态功能服务。     

火灾后钢筋混凝土损伤程度的灰关联分析

由于火灾对钢筋混凝土结构的影响存在不确定性,使得人们不能准确地确定火灾后钢筋混凝土结构的损伤程度,给评估和加固修复带来很大困难。本文运用灰色系统理论中灰关联分析数学模型定量分析了高温下钢筋混凝土梁的3种影响因素,并确定了各因素间的主次关系,为高温后钢筋混凝土结构的安全评估及修复加固提供了理论依据。

Matching response to context in complex political emergencies: 'relief', 'development', 'peace-building' or something in-between?

There is an ongoing debate over the value and pitfalls of the policy and practice of 'linking relief and development' or 'developmental relief' in aid responses to complex political emergencies (CPEs). Driven by concerns about relief creating dependence, sometimes doing harm and failing to address root causes of emergencies despite its high cost, pursuit of both relief and development has become a dominant paradigm among international aid agencies in CPEs as in 'natural' disasters. In CPEs a third objective of 'peace-building' has emerged, along with the logic that development can itself help prevent or resolve conflict and sustain peace. However, this broadening of relief objectives in ongoing CPEs has recently been criticised on a number of counts, central concerns being that it leads to a dilution of commitment to core humanitarian principles and is overly optimistic. This paper addresses these issues in the light of two of the CPEs studied by the COPE project: Eritrea and Somalia/Somaliland. It is argued that the debate has so far suffered from lack of clarity about what we mean by 'relief', 'development' and, for that matter, 'rehabilitation' and 'peace-building'. The wide spectrum of possible aid outcomes does not divide neatly into these categories. The relief-development divide is not always as clear-cut, technically or politically, as the critics claim. Moreover such distinctions, constructed from the point of view of aid programmers, are often of little relevance to the concerns of intended beneficiaries. Second, there has been insufficient attention to context: rather than attempting to generalise within and across CPE cases, a more productive approach would be to examine more closely the conditions under which forms of aid other than basic life support can fruitfully be pursued. This leads to consideration of collective agency capacity to respond effectively to diverse needs in different and changing circumstances.
