作者 周汝 何嘉鹏 +2 位作者 谢娟 王琼 彭红圃 《中国安全科学学报》 CAS CSCD 2006年第3期27-31,共5页
随着国内地铁的迅速发展,地铁火灾的防范及应急处理成为重要的研究课题。笔者根据地铁站建筑结构特点及火灾烟气的扩散规律,首次提出将空气幕用于地铁站楼梯口防烟,以保障火灾时人员的安全疏散。并用CFD方法模拟分析一列地铁列车着火时... 随着国内地铁的迅速发展,地铁火灾的防范及应急处理成为重要的研究课题。笔者根据地铁站建筑结构特点及火灾烟气的扩散规律,首次提出将空气幕用于地铁站楼梯口防烟,以保障火灾时人员的安全疏散。并用CFD方法模拟分析一列地铁列车着火时,防烟空气幕对烟气扩散的控制。结果表明,在楼梯口设置防烟空气幕不仅可以保证人员在6分钟以上的安全疏散时间,而且减少了比传统方式所需的新鲜空气量,有效阻止火灾的进一步扩大和控制烟气扩散。 展开更多

Statistical expression of vapour pressure equations of metals is derived from the Debye model.The statistical distribution of T_(-p) ensemble is presented in an in-elab- orate mode and the partition function is defined.The vapour pressure of eleven metals have been calculated with the Debye equation and compared with those given by the E- instein equation and empirical equation.Comparison of results of calculation from dif- ferent methods show their evident accordance within the same orders of magnitude. 展开更多
