摘　　要：报导了对爆炸磁压缩发生器（ＭＦＣＧ）的爆炸管进行的爆轰试验结果。用电子学方法测试了爆炸管采用的粉状ＲＤＸ炸药的爆轰速度；采用高速分幅摄影方法，观测了爆炸管在管内ＲＤＸ炸药爆轰产物驱动下的膨胀运动过程，测试了膨胀角、对称性和膨胀速度。试验表明，爆炸管在膨胀至３倍初始半径内未发现破裂现象，其性能满足ＭＦＣＧ的设计要求。This paper describes the detonation experimental result obtained by Magnetic Flux Compression Generator (MFCG) explosive tube.By means of electric method,the detonation velocity of RDX explosive powder used as explosive tube was measured;by means of high speed slit photography,the expansive process of the explosive tube driven by the detonation product of RDX was investigated,and the expanding angle,symmetry and expansive velocity were measured.The results show that the explosive tubes have not been found any fracture within the range of the explosive tube expanding to three times of the original radius.Its characteristic satisfies MFCG design.
