研究外界辐射加热下，不同重力环境中热薄燃料的着火特性．探讨了重力、环境氧浓度、环境压力及外界辐射强度对着火的影响．结果表明，随着重力的变化，存在不同的着火机制．在微重力和在高的环境氧浓度中，材料的着火延迟时间变短．压力减小，着火延迟时间增大．随着辐射强度的增大，着火延迟时间变小．
Study the ignition characteristics of hot thin fuel in different gravity environment under the radiation heating. The effects of gravity, ambient oxygen concentration, ambient pressure and external radiation intensity on the fire were discussed. The results show that with the change of gravity, there are different mechanisms of ignition. In microgravity and at high ambient oxygen concentrations, the ignition delay of the material becomes shorter. Pressure decreases, fire delay time increases. As the radiation intensity increases, the ignition delay time becomes smaller.
