以北京某地铁典型站台为研究对象,采用火灾动力学模拟软件FDS对站台中部起火和端部起火两种情况进行模拟,对热辐射、CO浓度、温度、能见度、烟层高度等值的变化进行了分析.结合现行地铁设计规范,得到站台中部起火时,“火源上方风机排烟,站台风机送风”方式;站台端部起火时,“A、C、E风机排烟,D风机送风”方式下,能确保在站台较大区域内烟气浓度值一定时间内较小,火场热释放速率、温度及CO含量等参数最优,提出了地铁在火灾工况下最优化通风方式. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献
