摘　　要：针对有毒烟气对飞机客舱移动受限空间人员疏散安全的影响,基于FED模型改进,建立客舱CO体积分数计算公式,提出安全曲线的概念。利用FDS模拟飞机客舱及出口处CO体积分数变化规律。结果表明:通过与CO体积分数安全曲线对比,可得出不同出口处超过人体承受阈值的时间。该研究可以为飞机客舱人员疏散出口及路线选择、应急预案编制及演练提供依据。To study the influence of toxic smoke on the cabin space evacuation of mobile limited aircraft, based on the im provement of FED model, the calculation formulas of CO con centration was deduced, and the concept of security curve was put forward. FDS was used to simulate the variation principle of CO concentration at the export of aircraft cabin. The results indicated that： by comparing with CO security curve, the time for CO concentration to exceed the endurable concentration of human can be obtained. The study can provide scientific basis for selection of aircraft cabin evacuation routes, selection of ex- port, and make and drill of emergency plans.
