只需改变结构的内外半径即可即可求解杆状结构和管状结构的相速度和群速度的频散曲线。-Just change the structure of the inner and outer radii can be solved phase velocity dispersion curves and the group velocity of the rod-shaped structures and tubular structures.

使用该程序可以实现TTI介质群速度的确定，全方位速度谱呈现(Using this program, the group velocity of TTI medium can be determined and the omnidirectional velocity spectrum can be presented.)
