And the shot peening surface micro morphology is acute deformationofsurface microstructure, lattice distortion and bidirectional cross-slip;
喷丸表面微观形貌为表层组织剧烈变形、晶格扭曲和双向交滑移；

In order to reflect the degree and trends of movement and deformationofsurface residue, some points should be arranged on the surface for monitoring.
为了确切反映地表残余移动与变形程度和趋势，需对采空区地表进行布点监测。

However, the displacement and deformationofsurface ground by underground mining have destroyed initial equilibrium between the building and the ground.
