爆炸后回收的冷凝物可以用常规的物理化学方法进行研究，也可以直接用于实践。从微观结构变化的三面性来考虑研究结果和应用领域是方便的，即力学是指固体的晶粒尺寸、表面、强度和硬度发生变化，物理是指原子结构发生变化，从而导致物体性质的变化，化学是指组成发生变化，产生具有各个层次新特性的新物质。通常，物质结构变化的深度随着激波强度的增加而增加。因此，我们从力学变化开始。
The condensed substances recovered after explosion can be studied by conventional physicochemical methods or directly used in practice. The results of investigations and fields of application are conveniently considered in terms of the three-faceted nature of microstructural changes, viz., mechanical when grain size, surface, strength, and hardness of solids change, physical when the atomic structure changes and this brings about changes in body properties, and chemical when the composition changes and a new substance is produced with new characteristics at all the levels. As a rule, the depth to which the matter structure changes increases with increasing shock wave intensity. Therefore, we begin with the mechanical changes.
