摘　　要：防火服装暴露在火场环境下,其表面温度会逐渐升高,并大量传热至人体,可能会造成皮肤烧伤。在燃烧假人闪火试验中利用红外热像仪测试试验服装以及假人的表面温度,研究发现闪火燃烧试验结束后,通过服装传递的热量使假人的表面温度在10 s内持续升高,四肢的升温速率大于躯干的升温速率;减少燃烧时间,使用面密度较大的面料会减小这种升温幅度;而增加闪火时间,穿着尺寸较小的服装会加大升温幅度。针对闪火燃烧试验结束后试验服装系统的散热性能,引入了新变量——着装假人系统的散热效能指数(γ)进行综合表征和比较分析。Exposure to flash fire, the surface temperature of the fireproof suit rises gradually and transfers a great deal of heat to the body of the wearer, and it might cause burn to the skin. The flame manikin system and the thermal infrared camera were used to capture the surface temperature of fireproof suit and manikin after flame exposure. The results showed that the surface temperature of the manikin rose continuously within 10 seconds after the end the experiment due to the heat transferred from the suit to the body, and the rising rates on the skin of arms and the legs are higher than those of the torso. Decreasing expoure time to fire, fireproof suit made of fabrics with larger surface density will reduce the margin of temperature rising; and increasing the expoure time, the small sized suit will increase the margin of temperature rising. A new parameter of the efficiency index of the heat dissipation about the flame manikin （γ） is introduced to characterize and compare the heat dissipation after the fire exposure.
