摘　　要：为研究某型双基推进剂老化后的热分解特性,对不同老化时间的双基推进剂进行热重分析(Thermo Gravimetric analysis,TG)和差示扫描(Differential Scanning Calorimetric,DSC)实验,计算不同升温速率下的反应动力学参数。实验结果表明:该双基推进剂的热安定性随着老化时间的增加而降低,但从总体上看,该型双基推进剂具有良好的热安定性和热安全性。In order to study an aging thermal decomposition performance of some double base propellant,Thermo Gravimetric analysis( TG) and Differential Scanning Calorimetric( DSC) experiments are conducted on the double base propellant sample of different aging time to acquire reaction kinetics parameter under different heat velocity. The results show that hot stability of the double base propellant decreases with increase of aging time,but totally,the double base propellant possesses good hot stability and hot safety.
