摘要
本文结出兰姆波非线性的一些理论结果，与非色散导波如表面波、界面波的非线性性质相比，具有更大的复杂性，表现为与Ｋｄ值、波的对称性及波模式的阶次均有关，且兰姆波的二次谐波只能为对称波。
The paper presents some theoretical results of Lamb wave nonlinearity. It shows that the nonlinearity of Lamb waves is related to kd values, symmetries and mode orders, and much complicated compared with that of nondispersive guided waves such as surface acoustic waves, stoneley waves. The second harmonics of Lamb waves are only symmetric.
