We analyze the effect of mass layer stiffness on thickness-twist waves propagating in a rotated Y-cut quartz crystal plate with thin mass layers on its surfaces. An equation that determines the dispersion relation of the waves is given and is solved numerically. Quantitative results of the effect of the mass layer stiffness on wave frequencies are presented. These results are important to the understanding and design of resonators and mass sensors.
我们分析了质量层刚度对在其表面带有薄质量层的旋转 Y 切石英晶体板中传播的厚度扭转波的影响。给出了一个确定波的色散关系的方程，并对其进行了数值求解。给出了质量层刚度对波频率影响的定量结果。这些结果对于谐振器和质量传感器的理解和设计具有重要意义。
