【摘要】 在兰姆波的激发过程中 ,一般采用的是各向异性的压电晶体。其不同切向激发出的兰姆波就有不同的特性。文章在兰姆波波动方程的基础上 ,分析研究晶体切向与兰姆波特性之间的关系 ,从中得出两者之间的关系 ,为以后在兰姆波器件的设计时选择合适的切向提供了理论基础更多还原

【Abstract】 In general,anisotropy piezoelectric substrate is used for the excitation of Lamb wavesThere are different characteristics of Lamb waves on the different crystal orientationIn this paper,the relations between crystal orientation and the characteristics of Lamb waves are presented based on the wave equationIt reaches the relations and provides theoretical basis for selecting the crystal orientation in device design更多还原
