约束条件对注装TNT中拐角效应的影响

THE EFFECT OF THE CONFINEMENT CONDITION UPON THE CORNER EFFECT IN CAST TNT

利用电探针技术测量了注装ＴＮＴ中主发药柱约束条件不同时，爆轰波绕射过程中在不同方向上传播的相对延迟时间。结果表明，缩短相对延迟时间可以通过以下两种方法：（１）利用约束材料提高主发药柱中爆轰波强度；（２）利用约束材料中冲击波的起爆能力。

In this paper,detonation wave corner turning in cast TNT was studied by means of electric probe technique.The relative delay time of wave arrival in various directions was measured under different confinement condition.The results show that the relative delay time can be reduced by means of (1)using confinement material to raise the strength of the detonation wave in donor charge,and (2) using the initiation ability of the shock wave in confinement material.
