摘　　要：采用X光照相和电探针技术进行低真空条件下炸药强爆轰驱动超高速飞片实验研究,得到了在不同时刻超高速飞片撞击静止靶的图像。实验结果表明,在低真空条件下,通过多级爆轰驱动方法得到次级飞片速度较高,而且具有相当好的平面性。The problem of accelerating metallic flyers to ultra-high speed by multi-stage detonation system at low vacuum conditions is studied in this paper by means of X-rays photography and electrical-pins technique.The pictures of the secondary flyer impacting static target at different time are obtained.The experimental results show that the secondary flyer accelerated by multi-stage detonation system at low vacuum conditions has an advantage of high velocity and good planarity.
