frame photography

By means of electric method,the detonation velocity of RDX explosive powder used as explosive tube was measured;by means of high speed slit photography,the expansive process of the explosive tube driven by the detonation product of RDX was investigated,and the expanding angle,symmetry and expansive velocity were measured.

用电子学方法测试了爆炸管采用的粉状ＲＤＸ炸药的爆轰速度；采用高速分幅摄影方法，观测了爆炸管在管内ＲＤＸ炸药爆轰产物驱动下的膨胀运动过程，测试了膨胀角、对称性和膨胀速度。

The high-speed photography was applied to observe the expanding fracture of 45 steel cylinder shells driven by detonation.

采用前照明高速分幅照相技术拍摄到在爆轰加载下45钢柱壳表面裂纹生成、扩展及产物泄漏过程的清晰图像,较准确地测量了膨胀断裂的时间与应变。
