摘　　要：为研究辐射情况下空气层位置不同对消防战斗服材料隔热性能的影响,基于织物热湿传递多孔介质模型,建立织物-空气层-皮肤系统热湿耦合模型,研究空气层厚度为1-10 mm,位于外层与防水层之间及舒适层与皮肤之间时,织物背热面及内部温度变化;基于生物传热方程,采用Henriques人体皮肤烧伤模型计算人体皮肤烧伤时间。结果表明：空气层厚度相同,位于外层与防水层之间时,织物-空气层系统的隔热性能优于空气层位于舒适层和皮肤之间的情况,人体皮肤烧伤时间极大延迟;当空气层位于外层与防水层之间,厚度大于7 mm时,人体皮肤烧伤时间出现突跃性增大;消防战斗服在进行设计时应增大外层与防水层之间空气层厚度,并且对于身体各部分分开设计。To investigate the influence of air gap position on the heat insulation performance of the firefighters＇ protective clothing, a fabric-air gap-skin system heat and moisture transfer model was developed based on the fabric heat and moisture transfer porous medium model. Temperature variations on the inner and outer surfaces of the sample were monitored when the air gap is located between the outer layer and the moisture layer and between the comfort layer and the human skin at the same thickness of 1-10 mm. Then the maximum duration of heat before subjecting to first and second-degree burns were calculated by the Henriques equation based on the bio-heat transfer equation. The results show that, the thermal insulation performance of the fabric-air gap system when the air gap is located between the outer and moisture layer was better than that when that located between the comfort layer and the human skin at the same thickness. And the time before human skin subjecting to first and second- degree burns was also prolonged when the air gap is located between the outer layer and the moisture layer, especially when the air gap thickness is greater than 7 mm. Therefore, the air gap between the outer layer and the moisture layer should increased when the firefighters＇ protective clothing was designed. And it should be designed separately for different parts of the human body.
