论文摘要
我们研究各向异性晶体中的宏观和晶格波传播，被视为具有仿射微结构（或微态）的连续体。在一般情况下，我们获得了有关频率和分散房屋的定性信息。然后，这些结果专门针对四方点组的晶体，用于各种传播方向：声音和视频频率的精确表示以及沿四方C轴的传播方向获得了耦合振动模式。
We study the coupled macroscopic and lattice wave propagation in anisotropic crystals seen as continua with affine microstructure (or micromorphic). In the general case we obtain qualitative informations on the frequencies and the dispersion realtions. These results are then specialized to crystals of the tetragonal point group for various propagation directions: exact representation for the acoustic and optic frequencies and for the coupled vibrations modes are obtained for propagation directions along the tetragonal c-axis.
