一条直接途径被兰姆波浪繁殖在一个稳固的盘子中为累积的秒泛音的一般答案开发了。由兰姆波浪的秒泛音产生的现在的分析集中于基本兰姆波浪的阶段速度确切或近似等于双频率兰姆波浪(DFLW ) 的盒子。基于获得的一般答案，累积秒泛音回答的数字分析表演与在基本兰姆波浪和主导的 DFLW 部件的阶段速度之间的刺激来源和差别的位置被联系。

英文摘要：

A straightforward approach has been developed for the general solution of cumulative second harmonic by Lamb wave propagation in a solid plate. The present analyses of second-harmonic generation by Lamb waves focus on the cases where the phase velocity of the fundamental Lamb wave is exactly or approximately equal to that of the double frequency Lamb wave （DFLW）. Based on the general solution obtained, the numerical analyses show that the cumulative second-harmonic fields are associated with the position of excitation source and the difference between the phase velocity of the fundamental Lamb wave and that of the dominant DFLW component.
