First , we analyze the relation between thickness-shear and flexural vibrations mode in the AT-cut quartz crystal plate by Mindlin elastic plate theory , then obtain the result by the improved Mindlin plate theory , finally compare them and find the differences . The result of improved Mindlin plate theory excelled the Mindlin plate theory .

我们首先用Mindlin弹性板理论分析了AT切石英晶片中厚度-剪切和弯曲振动模态之间的色散关系，再用修正后的Mindlin板理论得到色散关系，并对两者进行比较说明，修正后的Mindlin板理论得到的结果明显要优于Mindlin板原理论。
