摘　　要：本文介绍了用激光引爆炸药过程中,测量炸药在靶内引起的应力波历史时,激光器的冲击大电流在周围空间引起强烈的电磁干扰.文章中估算了周围空间的场强,说明了编织网电缆线、缝隙、孔洞,对电磁场的泄漏,需要采用全封闭型的屏蔽,才能较好地抑制干扰,获得比较理想的屏蔽效果。When we ignite the explosive by pulsed laser to measure the explosive oringinat- ed stress-time history in the target,an intense electromegnetic interference of the pulsed high current is introduced in the surrounding space.In this paper,the field strength in the environmental space is evaluated,and the leakage of electromagnetic field through the braid of cables,the seams and holes is explained.Only if we use it with solid conductor shield,the leak- age can be so minimized that more effective shielding is obtained.
