Based on the analysis method of partial plane waves of elastic guided waves, the acoustic fields of Lamb waves in solid composite layers were analyzed. 基于弹性导波的部分平面波分析方法,对复合固体层中兰姆波的声场分布问题进行了研究。
In this part, method of partial waves and phase-shift analysis are brought into the theory. Chung理论,建立了相对协变的螺旋振幅分析方法,把分波法和相移分析纳入理论,进行统一表述。
