Dear Huang:
Thanks very much for your help:)

 LO-TO splitting always exists in Brillouin zone, but two points are worth
> noting:
I do not think so. I do not find any LO-TO splitting at the X and R point of
Brillouin zone of cubic.
Because I use finite difference method, I do not know LO-TO splitting
persists at other part.

> (2) only cubic crystals has LO and TO braches.
The LO-TO splitting exists also in uniaxial crystal(direction dispersion in
