摘　　要：为了研究含湿量对RDX的机械感度和热分解特性的影响,采用爆炸概率法和升降法,分别在HGZ-1型撞击感度仪上和MGY-1型摩擦感度仪上对不同含湿量的RDX进行感度测试,并对不同样品进行DSC测试分析和热力学理论计算,得到不同含湿量对RDX爆炸活化能和起爆能量临界值的影响规律。结果表明:含湿量对RDX机械感度有明显影响,机械感度与含湿量呈负相关性;湿分会降低RDX的爆炸性能,含湿量越大,RDX起爆所需能量越高,物料越不易起爆。In order to investigate the influence of moisture content contained in RDX on the mechanical sensitivity andthermal decomposition,used explosion probability method and fluctuation method,RDX containing different moisturecontents were employed to test their sensitivity using HGZ-1impact sensitivity instrument and MGY-1friction sensitivityinstrument.Besides,the DSC test analysis of different samples was carried out,and the influence of different moisturecontent on the explosion activation energy of RDX and the critical values of initiation energy were studied.The resultsshowed that the moisture content of RDX had great influence on the mechanical sensitivity which was negatively correlatedwith moisture content;moisture contained in RDX would reduce the explosion performance of RDX.If the moisturecontent was higher,the more energy was need for RDX explosion,therefore the RDX c was not easy to burst.
