摘　　要：本文采用Hopkinson压杆试验装置对硼系延期药进行应力波加载试验。比较了压药压力、过载加速度以及粘合剂的使用对硼系延期药在动态加载前后延期时间与延期精度变化的影响。经试验表明:延期药在高过载下延期精度下降很大;在延期药中加入粘合剂可以相对提高延期体的抗过载能力。A Hopkinson pressure bar technique was used to test the burning performance of boron type delay charge, in which the delay time and the precision of the composite were compared before and after shock. Tested results showed that the precision of buming rate can been declined after load at high acceleration, and the overload performance will be improved mixing adhesive in composite.
