摘　　要：用差示扫描量热计（DSC）研究了单基、双基和三基药热分解性能。讨论了不同起始温度和升温速率对火药热分解的影响，并对这些火药热稳定性进行了比较，以期对螺压工艺中这些火药热行为的了解提供有益信息。The thermal decomposition of single, double-and triple-base nitroguanidine propellants was studied by differential scanning calorimetry (DSC). The effects of initial temperature and heating rate on the thermal decomposition of proPellants were discussed. The thermal stability of these propellants was compared in order to provide useful information concerning the thermal behaviour of these propellants during screw extrusion.
