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

For strong anisotropycrystal, the maximum incident Angle that yields the negative refraction could be very large.
各向异性强的晶体实现负折射的入射角范围可能会很大。
