Ⅰ.引言常规的低成本军械引信的爆炸序列都是利用一种保险与解除保险装置使其爆炸通道对准而完成的。该保险与解除保险装置将隔离体从两种可爆元件之间移开和/或将一爆炸元件移动到隔离体的传火孔位置。这样,几乎所有的延期齿轮传动系及其它小型精密机械部件都需 I. INTRODUCTION The detonation sequences of conventional low-cost ordnance fuzes have been accomplished by aligning their explosion passages with a fuse and release mechanism. The fuse and release device removes the spacer from between the two explosive elements and / or moves an explosive element to the fire hole of the spacer. In this way, almost all deferred gear trains and other small precision mechanical components are required
