摘 要: 对各种材料在承受不同压力作用下所呈现出来的不同声学显微结构进行了分析、比较，研究发现：不仅声速随承受载荷变化而变化，且声学显微组织也随承受载荷而变化。这种在弹性变形下表现出来的内部结构畸变，表现了材料一种新的声学性能。

Abstract:The materials' acoustic microstructures under different loading conditions were analysed. The results indicate that not only the sound speed but also the materials' acoustic microstructures change with the load. The structures distort in the condition of elastic deformation, which reflects a new acoustic property of materials.
