摘　　要：通过水下爆炸试验研究了RDX和HMX对EAK基熔铸分子间炸药水下能量的影响。结果表明,RDX和HMX对EAK基混合炸药起到明显的增能作用,但对含铝和非含铝体系有不同的作用效果。爆速和撞击感度测定表明,EAK-RDX混合炸药爆轰的理想化程度和稳定性及撞击感度随RDX含量的增加而增加。从能量和撞击感度两个方面综合考虑,RDX的较佳加入量应为20%～30%。The effect of RDX and HMX on the energy of EAK based melt cast intermolecular explosive was investigated by the underwater detonation energy testing which was carried out in a water pool with a diameter of 10 m and depth of 7 m, and the samples were about 300 g and set at 4 m under the water. The results indicated that all of RDX and HMX promoted the energy of EAK composition, but there was difference between aluminized and non-aluminized explosive composition systems. In the aluminized explosive compositions RDX was more effective on promoting underwater energy than HMX,but in the non-aluminized explosive compositions, HMX was more effective than RDX. The tests of detonation velocity and impact sensitivity for the EAK-RDX mixtures showed that ideality and propagation stability of detonation, and impact sensitivity all increased with increasing the content of RDX. The mixtures containing 20% and 30% RDX could come to a detonation velocity of 7 800 m/s and 8 000 m/s respectively, and their impact sensitivity both were less than 10%. The impact sensitivity increased sharply as the content of RDX was higher than 40%, while the detonation velocity just showed a smooth increasing. According to tradeoff between the energy and the impact sensitivity, the suitable content of RDX in the EAK composition was about 20% to 30%.
