对于0 0 0 2的非弹性碰撞入射原子约化质量增大，大角散射几率增大。
For 00 02 inelastic collision, scattering at the large Angle keep pace with the increase of reduce mass of incident atom.
随着色散的加强，激子的有效质心质量、有效约化质量增大，电子-空穴有效作用势的屏蔽半径变短。
It is found that the more the phonon dispersion, the larger is the effective mass, and the smaller the screening radius of electron-hole effective interacting potential.
