| Abstract: | The symmetry change in ferroelastic phase transition can be determined by analyzing the solution of the Christoffel equation. The acoustic mode of hexagonal system softening corresponds to the maximum slowness. The eigen vector of soft mode is given by the polarization of acoustic wave. |

| Keywords: | slowness curved surface eigen vector of soft mode ferroelastic phases transition |
