高层建筑火灾中安全疏散的评价分析

由于高层建筑的迅猛发展,高层建筑的火灾防范和安全疏散成为一个重要的研究课题。笔者阐述高层建筑的火灾特点,以及人员安全疏散的安全评价在消防中的重要作用;综述火灾危险分析的方法;介绍几种可以用于安全疏散的评价方法,并结合各种评价方法的优缺点进行了比较。根据实际情况,选择了模糊综合评价法对某一高层建筑作了简单的算例,从其结果中可以看出:疏散楼梯、防排烟和通风空调系统及事故疏散标志、通信设备存在一些问题,需要整改,以确保人员疏散的安全性;制定相应的应急预案,调整人员疏散策略,确保火灾中人员安全、及时、迅速撤离火灾现场,至安全区域。     

防灾高专非外语专业英语口译课教学工作探讨

本文对高职高专院校里在非外语专业开设及如何开展外语口译课程的教学工作进行了两方面的初步探讨。首先介绍了我国目前高校里的外语教学普遍以小班教学的模式,接着就如何在高校非外语专业学生中快速培养实用型的涉外口译人才而采用的另外一种教学模式,最后分别就其所在学校如何抓口译教材建设和抓课堂教学质量等方面工作并结合自己的教学实际进行了探讨。     

火灾烟气中有毒气体的体积分数分布与危害

研究火灾烟气的成分与其体积分数分布是火灾科学的一项重要内容。为了更好地研究建筑火灾烟气的释放过程并为建筑材料评价提供依据，采用文献综述的方法论述了建筑火灾烟气的主要有毒成分、体积分数范围(即浓度范围)与危险含量(即危险浓度)，还介绍了常用的烟气分析方法，说明了对火灾烟气的产生机理和火灾烟气成分的检测方法等还需要进行深入的研究。     

Policy implementation of the Republic Act (RA) No. 9003 in the Philippines: A case study of Cebu city

Municipal Solid Waste Management (MSWM) is considered to be one of the most serious environmental issues in the Philippines. The annual waste generation was estimated at 10.6 million tonnes in 2012 and this is expected to double in 2025. The Republic Act (RA) No. 9003, widely known as the Ecological Solid Waste Management Act of 2000, provides the required policy framework, institutional mechanisms and mandate to the Local Government Units (LGUs) to achieve 25% waste reduction target through establishing an integrated solid waste management plan based on the 3Rs (reduce, reuse and recycling). Although the initial impact of the LGUs is still very limited in implementing the national mandate, this article highlights the successful experiences of Cebu, the second largest city in the Philippines, in reducing its MSW generation by more than 30% in the past three years. This study also explores the implementation process, innovative actions taken by the Cebu City Government in implementing the national mandate at local level and identifies the factors that influence the policy implementation. The findings suggest that the impacts of the national mandate can be achieved if the LGUs have the high degree of political commitment, planning and development of effective local strategies in a collaborative manner to meet with local conditions, partnership building with other stakeholders, capacity development, adequate financing and incentives, and in the close monitoring and evaluation of performance.     

Proposing of new building scheme and composite towards global warming mitigation for Malaysia

The building sector has been regarded as a potential sector where there is large capacity to reduce the climate change effect. This study has proposed solutions to mitigate environmental impacts and achieve low CO₂ emission from residential sector. Therefore, full life cycle assessment (LCA) has been run to assess the CO₂ emission and its effect on the atmosphere and climate change. Based on the result, timber scheme is the best choice due to releasing less CO₂ emissions to the atmosphere. However, house builders in Malaysia have almost completely neglected timber as a building material, with timber use as building components reduced to 5%. In this study, LCA Software was used to assess CO₂ emissions from different wall construction. The alternative building scheme has been made by reinforce steel stud, wooden beam and timber wall (S8) to improve the scheme deficiency while releasing less CO₂ emissions compared to other schemes. Therefore, S8 has a decreased CO₂ effect by 85% less than precast concrete frame and 90% less than brick over their lifetime. (S8) increased the load bearing compared to conventional timber beam. Thus, new scheme S8 could be replaced by current scheme and promote more adjustable scheme for Malaysian housing.     

西北地区水资源—生态可持续发展的若干问题探讨

基于对西北地区大开发的关键性难题与一些违背自然规律的不良倾向的讨论 ,认为大开发的实施需要在系统科学思维的基础上综合考虑资源—环境—经济的协调发展。近年来 ,许多科学家从各种角度揭示了我国西北乃至北半球中纬度地区持续干旱的发展规律 ,对干旱化趋势与水盐失衡的分析表明 ,西北地区气候干旱化将长期存在 ,生态将继续退化 ,这种趋势是人力不可抗拒的。人为活动尤其是水资源的开发利用 ,对土壤生态的影响是非常明显的 ,应该在严格控制水资源利用总量的前提下 ,调整用水格局 ,发展节水经济 ,科学确定社会经济用水和生态用水的比例 ,保证必须的生态用水 ,大力发展生态植被。指出在分析西北生态环境问题时过于强调人为活动而忽视自然因素作用的倾向 ,讨论了水库兴修、灌溉、土地利用与改良、深层水利用、水环境脆弱性等水资源—生态建设与可持续发展中的若干关键性问题     

重庆村镇住宅热湿环境现状及评价

通过对重庆地区村镇住宅的实地调研和村镇典型住宅温湿度连续监测,获得了重庆地区村镇住宅的主要围护结构形式以及典型房屋2010年1～9月的室内热湿环境状况,并利用重庆地区自然通风适应性热舒适性评价模型进行了分析。结果表明：现有墙体热工性能最好的是180红砖内外水泥砂浆抹灰外贴瓷砖形式,测试房屋冬季室内最低温度为83℃,最高相对湿度为962%,夏季室内最高温度为344℃,最高相对湿度为99%。监测数据中相对湿度大于70%的时数占总测试时数的93%。住宅围护结构的冷热抵御能力和湿舒适湿卫生条件都很差。采暖季节室内达到舒适只有2 d,空调季节有58 d,村镇地区围护结构冬季保温要求比夏季隔热显得更为突出
