摘　　要：为研究高海拔对于火灾燃烧特性的影响,采用火灾试验研究的方式分别在高海拔地区和内地进行了火灾的燃烧试验,测得了不同尺寸油盘火源试样的燃烧时间和热释放速率,通过对比试验结果分析得到:高海拔地区火灾燃烧热释放速率相比内地较小,但是燃烧时间远比内地长,燃烧的火焰高度更高。Combustion heat release rate of fire plays an important role for fire risk assessment and fire simulation, but combustion characteristics of fire in high-altitude zone are different from those in inland,therefore, it is not easy to determine the combustion heat release rate. To study the impact of high-altitude on combustion characteristics of fire, fire burning tests were conduc- ted at high-altitude zone and inland area. The burning time and heat release rate of the five in dif- ferent size oil pan were measured, analysis by comparison gave the results： the heat release rate of the fire in high-altitude zone is lower than that in inland, but the burning time is longer, and the burning flame height is higher.
