摘　　要：固体化学氧气发生器利用氯酸盐发生热分解反应提供氧气,用燃速温度敏感性表征环境温度对固体化学氧气发生器供氧性能的影响程度。改变固体化学氧气发生器配方,测试固体化学氧气发生器的燃烧供氧性能,找出影响固体化学氧气发生器燃烧温度敏感性的主要因素。实验结果表明,适当的金属粉含量、不加催化剂、添加稳定剂可有效降低固体化学氧气发生器燃烧温度敏感性,能够保证固体化学氧气发生器在不同环境温度下的供氧流量和供氧时间的一致性。Solid chemical oxygen generator provides oxygen by the chlorate thermal decomposition reaction. The effect of envi- ronment temperature on the oxygen supply performance of solid oxygen generator is characterized by the burning rate temperature sensitivity. The oxygen candle formula was changed and the combustion performance was tested though experiment. The factors af- fecting temperature sensitivity affecting candle combustion were analyzed. Results show that choosing the proper contents of metal fu- el, taking out catalytic agent and adding stabilizing agent could reduce solid chemical oxygen generator temperature sensitivity. It could meet the oxygen supply time and flow technical standards in a wild temperature range.
