Study of fire-extinguishing performance of portable water-mist fire extinguisher in historical buildings     

Zhou Xiaomeng  Zhou Biao  Jin Xiang 《Journal of Cultural Heritage》2010,11(4):25-397

This paper describes both theoretical and experimental studies on the application of a portable water mist extinguisher in suppressing flammable liquid and wood crib fires. At first, the interaction between water mist and fire plume is studied by analyzing the instantaneous process of fire extinction. And then, the feasibility in extinguishing diesel oil, gasoline and wood crib fires is studied by a series of experiments. Theoretical analysis and experimental results show that the extinguishing mechanisms and process change with the difference of water mist characteristics (such as water flux density, droplet velocity and diameter), and the portable water mist fire extinguisher with appropriate characteristics was able to extinguish Class A and Class B fires. It is a potential fire protection means for historical buildings.  相似文献   

《历史知识在地理教学中的渗透》——高职旅游专业地理教学中跨学科知识的渗透     

施隽 《南昌教育学院学报》2013,(4):97-98

俗话说史地不分家,两门学科之间有着千丝万缕的联系,而对于地理学科的分支学科《旅游地理》而言,由于其涉及到了更多人文文化和历史典故与传说,这就使其与历史学科间的关系更加的紧密,作为一位中职学校旅游专业的地理教师,通过日常的教学实践,在这方面略有体会,在此把这些体会感受写出来与大家分享。  相似文献   

Using inquiry-based instruction to encourage teachers' historical thinking at historic sites     

《Teaching and Teacher Education》2013

This study explores the use of inquiry-based instruction for constructing historical understanding in historic site-based teacher professional development programs. In an historic site-based professional development workshop, fifteen teachers of grades 5 through 12 engaged in guided inquiry with documents drawn from said historic site. Participants showed significantly increased curiosity about the site and use of problem-solving strategies in interactions with the site and staff, but no improvement in other elements related to historical thinking at historic sites. Improvements correlated to neither length of teaching experience nor testing group characteristics, indicating broad applicability for improving historic site-based professional development programs.  相似文献

关于新历史主义与新历史小说     

陶汝崇 《临沧师范高等专科学校学报》2007,(1):28-30

作为一种新的历史观和新的文学批评方法，新历史主义在20世纪末期颠覆了传统的历史叙述和文学叙述。它传人中国以后，也自然对中国的历史小说创作有着一定的影响，以至于很多人认为，中国的新历史小说就是在新历史主义的历史观念影响之下而形成的，两者在历史观上是一致的。然而，作为西方舶来品的新历史主义和中国土生土长的新历史小说之间在历史观念上有着很大的不同，两者之间并不能直接划等号。文章即拟对两者之间的差异作初步探讨。  相似文献

开放性课程资源在五年制学前教育专业地理教学中的应用研究     

杨达 《教育与教学研究》2011,(9):72-75

新的地理课程标准强调学习对生活有用的、对终身发展有用的地理。非常重视校外地理课程资源的开发利用,形成学校与社会、家庭密切联系,教育资源共享的开放性课程。开放性是指进行课堂教学时所摄取的资源不仅仅局限于课堂上和书本里,要挖掘蕴藏在学校、家庭、社区、社会生活中更为丰富的课程资源。五年制学前教育专业学生的学习能力不是很强,只有充分利用开放性课程资源进行教学,才能很好地提高课堂教学质量,改善教学方法,激发学生学习的兴趣,培养学生的综合能力,完成课标要求。  相似文献   

Urban sportscapes: An environmental deterministic perspective on the management of youth sport participation     

《Sport Management Review》2015,18(2):291-307

This paper examines sport participation from an environmental perspective by considering the dynamic role of the sportscape (built-form and supporting infrastructure) in enabling, facilitating and promoting youth sport participation. Complementing recent work by Wicker et al. (2013), we conduct a case study of the ‘geography of sport’ in the Greater Toronto Area. In the process we introduce the concept of facility ‘gravitas’ to capture the attractiveness or ‘magnetism’ of sportscape entities and thereby acknowledge the multifaceted sets of environmental factors (including the bricks-and-mortar of facilities and the supporting mechanisms such as transportation, coaches and clubs) that influence sport participation. The results demonstrate that the geography of sport is not only about where sport venue built-forms are located, but also what types of sport infrastructure are available. To develop a better understanding of sport participation it is important to assess the capacity and quality of the sportscape along with other supporting structures and facilitators. The paper points to the implications for managers and policy makers from this perspective.  相似文献
