摘　　要：为了发展适应于高原地区低压低氧环境下的火灾防治技术,基于高原地区建筑特点和防火重要性,建立用细水雾灭火技术来防治高原建筑火灾的方法。在中国拉萨进行细水雾添加剂灭火模拟试验,研究添加剂FeCl_2和NaCl对细水雾熄灭汽油和柴油池火的灭火性能的影响,分析试验过程的温度、烟气、辐射热流变化规律。结果表明,在拉萨地区低压低氧的环境下,分别含质量分数为1.5%FeCl_2和10%NaCl的细水雾对柴油池火的灭火效率较高,而汽油池火初期受到了抑制,但随后出现了强化现象,最终未被熄灭。含添加剂FeCl_2和NaCl的细水雾对高原地区柴油池火有较高的灭火效率。The paper was aimed at developing a efficient fire prevention and control technology for plateau hypoxia environment. Based on construction characteristics and urgency of fire protection in plateau area,fire suppression experiments with additives and water mist were carried out in Lhasa,China. The experiments involved gasoline pool fire and diesel oil pool fire suppression with water mist and additive Fe Cl2 and Na Cl. Changes in temperature,smoke concentration,and radiation flux during the experiments were analyzed. The experimental results showed that under the condition of low pressure and hypoxia in Lhasa,water mist with 1. 5% Fe Cl2 and 10% Na Cl had good performance at fire suppression of the diesel oil pool fire,and that,gasoline pool fire was mitigated at first,but then appeared strengthening phenomenon subsequently,gasoline pool fire was not extinguished eventually. These explain that additive Na Cl and Fe Cl2 have good adaptability and high efficiency on fire suppression in the plateau region.
