位移固定、滑動)下的頻散方程式，繪製了不同材料在不同邊界條件下的
頻散曲線圖並對結果加以討論。

This article investigates the behavior of the propagation of elastic waves in anisotropic materials. By employing the elastic waves propagation in anisotropic materials which satisfy the equation of motion, stress-strain and displacement-strain relations, we briefly outline the derivation of dispersion equations for general anisotropic materials.
We first focuse on the problem of dispersion curves for a plate with a totally traction-free or totally rigid boundary conditions on the upper and lower surfaces of plate. Next, we investigate the problem of dispersion curves for various boundary conditions (traction-free, rigid, slippery) prescribed on the surfaces of the plate. Numerical results are presented for different types of materials and results are discussed.
