摘　　要：建筑火灾中致人死亡的因素除了热以外,更多的是因为烟气的毒性.通过实验系统研究了典型侧间 走廊建筑结构中的烟气浓度场的分布以及烟气迁移到远距离处的特征,并结合数值分析,讨论了建筑结构形式对烟气毒物迁移的影响.实验中发现,由于建筑结构的影响,离火源近的点烟气毒物的浓度反而比远点低,并对此现象进行了初步的分析.The smoke takes the leading role of the lethality of the people in the fire apart from heat. A series of experiments and numerical analysis are carried out in this paper, focusing on the smoke species concentration distribution within the typical building structure of Room-Corridor and the location remote from fire origin. And the comparison of both methods is also offered with many clear conclusions. The effect of the building structure on the smoke species transportation is primarily discussed to discover some unusual phenomenon.
