摘　　要：采用HPLC、XPS等方法对塑料粘接炸药试件与聚合物的接触、非接触体系在不同温度下贮存不同时间的性能进行了表征,结果显示:1)塑料粘接炸药试件的质量、TNT含量均随贮存温度的升高逐渐降低,其表面的N元素含量随贮存温度的升高逐渐增大;2)在相同温度下,这些性能变化到一定程度后基本不再随贮存时间的延长发生大的变化,且这些变化多为塑料粘接炸药试件自身的一些小分子在热作用下发生升华、迁移所致,聚合物对其影响很小。The properties of PBX specimen,polymer and their contact system aged at different temperatures for different time were characterized by HPLC and XPS methods.The results show that：1）The mass and TNT content of PBX specimen decrease with the storage temperature rising,while the N element contents in the surface increase with the storage temperature rising;2）At constant temperature,the changes of these properties suspend after it reach a certain extent,which are mainly caused by sublimation and migration of some small molecules in PBX specimen and hardly influnced by the polymer.
