中文摘要:
      文章采用传递矩阵方法研究固液固3层结构板中兰姆波的传播,数值计算结果证明了用该方法分析层状材料中的兰姆波的有效性与实用性。文章计算出的多种频散曲线对超声兰姆波的应用是有益的。
英文摘要:
      Transfer matrix method is used to study the propagation of Lamb wave in solid-liquid-solid three-layered structure. Numerical calculations proved that the method is effective and practical to analyse the Lamb wave in layered structure. The varied dispersion curves worked out this paper is helpful in application of ultrasonic Lamb wave.
