本文从理论和实验两方面研究了速度弥散和非速度弥散情况下声表面波的非线性效应。首先，报告表面波器件中非线性效应的研究结果。其次，它表明，在声表面波的非线性效应可以控制的速度色散;即，当声表面波的速度色散增加，非线性效应减少，当声表面波是免费的速度色散，非线性效应增加。实验是用131 °旋转Y切割X传播LiNbO3的样品进行的，基频约为300 MHz。
Theoretical and experimental investigations are made of nonlinear effects in acoustic surface waves with and without velocity dispersion. First, the results of the investigation of nonlinear effects in surface‐wave devices are reported. Second, it is shown that the nonlinear effects in acoustic surface waves can be controlled by velocity dispersion; namely, when the velocity dispersion of acoustic surface waves is increased, the nonlinear effects are reduced, and when the acoustic surface waves are free from velocity dispersion, the nonlinear effects are increased. The experiment was conducted with specimens of a 131°‐rotated Y‐cut X‐propagating LiNbO3, and the fundamental frequency was about 300 MHz.
