| 摘要: |
| 平面动载实验中, 飞片碰撞速度和碰撞状态是加载条件的一个基本描述。本文采用电探针技术, 给出了一个同时测得真实飞片速度和碰撞倾斜状态的探针排布设计。此设计用于化爆产生平面动载的氮化硅粉体冲击波活化研究, 取得了较为理想的测试结果。 |

| Abstract: |
| In plane dynamic loading experiments, the velocity of flyer and state of impact are key parameters of loading condition. A technique of electric pins for measuring the above parameters is designed, aiming at deducing a real velocity of flyer and slant of impact from local records of pins signs through a certain arrangement of the pins. The method has been used in experiments of shock activating Si3Ni4 powder materials, and the results are satisfactory. |
