摘　　要：烟气的影响是火灾中人员死亡的最主要原因,为此利用"房间-走廊-房间"结构的模拟实验台进行了大量的实验,研究了火灾中烟气有毒成分向远距离非火源房间传播的特点.结果表明,门的作用非常显著,温差和一氧化碳浓度都随着门高度的增加而有规律地增加,一氧化碳浓度峰值的出现会随着门高度值变小而显著延迟;温度与一氧化碳浓度在垂直方向的分布差别很大,这说明烟气温度和毒性成分在远距离房间垂直方向上分布相互不一致.Lethality of victims in fires mainly results trom smoke, A set of conducted in a room-hallway-room structure apparatus to study the characteristics of toxicant species of fire smoke travelling to the remote room. Results indicate the obvious influence of the room door on the smok, movement, that is, the values of temperature and CO concentration increase as the door height increases and the arrival of the CO concentration peak is delayed noticeably as the door height decreases. Analysis o the data indicates that vertical distribution is of great difference between the smoke temperature and th CO concentration, which demonstrates that the temperature distribution is not consistent with the toxican species in the upper space of the remote room.
