【摘要】 通过冲击、压缩及燃烧中止试验，借助ＳＥＭ观察冲击断裂面和中止样品表面的结构特征，比较了两种硝胺发射药ＲＧＤ７和ＲＨＤ６在不同温度下的力学性能。ＲＨＤ６的冲击强度、抗压强度及压缩率均大于ＲＧＤ７，中止样品破损率低于ＲＧＤ７，断口和中止表面状况也得以改善，证实ＲＨＤ６是一种有希望的新型发射药。更多还原

【Abstract】 By means of compact, compression and combustion extinguished test, as well as morphology of impact fractured and combustion extinguished surfaces, the mechanical property of two nitromine propellants (RGD7 and RHD6) are compared at different temperature. It shows that impact strength, compression strength and percentage of RHD6 are higher than that of RHD7, its damaged percentage is lower, and its impact fractured and combustion extinguished surfaces are improved. From the results, it may be suggested that RHD6 is a new type of propellant.更多还原
