建立了一个描述高斯光束入射液/气/固角时兰姆波和瑞利波激发的模型。应用考虑反射波贡献的模态理论，导出了所产生模态位移场的解析表达式。数值计算表明，在最佳条件下，兰姆波和瑞利波的最强刺激可能是预期的。
A model is developed to describe the excitation of Lamb and Rayleigh waves by a Gaussian beam incident on a liquid/air/solid corner. Analytical expressions for the displacement fields of the generated modes are derived by applying a mode theory that accounts for the contribution of the reflected waves. Numerical computations illustrate the optimum conditions under which the strongest stimulation of Lamb and Rayleigh waves may be expected.
