利用波扰动方程，分析研究了声表面波器件频率-温度敏感性与石英晶体各向异性参数之间的关系。

The temperature sensitivity of the frequency as a function of quartz crystal anisotropy is presented by the perturbation equation due to the temperature change.

当波从小扰动源向各个方向均匀传播时，其强度的变化与距离的平方成反比。

When a wave travels uniformly in all directions from a small source, the intensity varies inversely as the square of the distance.

考虑了弹塑性应力波传播对屈曲的影响，建立了该问题横向扰动方程。

The equation of lateral disturbance used to analyize the problem is developed by taking into account the effect of elastic-plastic stress wave.
