摘要
在水泥臼板中的冲击波的相互作用被数字点缀关联方法和数字高速度的摄影技术学习。当盘子被同时爆炸的二根雷管破坏时，冲击波地的变化被获得。试验性的结果证明冲击波的相互作用将导致本地正常紧张的非线性的巨大的增加，导致大变丑和严肃的破坏。然而，这强烈非线性的现象的出现易感知地取决于在雷管之间的间隔，并且间隔什么时候比在哪儿的区域的直径小，将仅仅出现冲击波存在。
Interaction of shock waves in cement mortar plate is studied by digital speckle correlation method and digital high-speed photography technique. When the plates were destroyed by two detonators exploding at the same time, variation of shock wave field is obtained. Experimental results show that the interaction of shock waves will result in a nonlinear huge increase of local normal strain, leading to large deformation and serious destruction. However, the occurrence of this strongly nonlinear phenomenon sensitively depends on the interval between detonators, and it will only appear when the interval is smaller than the diameter of the region where shock waves exist.
