摘 要: 對(duì)各種材料在承受不同壓力作用下所呈現(xiàn)出來(lái)的不同聲學(xué)顯微結(jié)構(gòu)進(jìn)行了分析、比較，研究發(fā)現(xiàn)：不僅聲速隨承受載荷變化而變化，且聲學(xué)顯微組織也隨承受載荷而變化。這種在彈性變形下表現(xiàn)出來(lái)的內(nèi)部結(jié)構(gòu)畸變，表現(xiàn)了材料一種新的聲學(xué)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.
Key words: materials acoustic microscope microstructures deflection characteristics
