Abstract: The relativity of pyrolytic characteristics and catalytic activites of some NTO salts used as ballistic modifier was discussed.It is believed that there are some relationships between them.Therefore,the pyrolytic charateristics can be used as a criterion to evaluate the catalytic activities

摘要： 采用高压差示扫描量热仪，研究了几种ＮＴＯ（３－硝基－１，２，４－三唑－５－酮）盐在不同压力下的热分解特性，同时测定了以ＮＴＯ盐为催化剂的固体推进剂的燃速特性。结果认为，这些ＮＴＯ盐的热分解特性与催化特性间存在某种联系，热分解行为压力不敏感的ＮＴＯ盐，可能会是较好的燃速催化剂。因此热分解行为可作催化能力的判据之一。
