surface discontinuity

In 3-D surface profilometry by means of high-speed laser sheet, since the increase of distance between two optical cross-sections, the discontinuity on the object surface will lead to an erroneous triangular facet and distorted surface reconstruction.

在高速光截法三维面形测量中，由于光截面之间距离增加，物体表面的不连续性将容易导致错误的三角网格化，引起面形重建的畸变。

NICK: Surface discontinuity, a depression or dent caused by impact.

刻痕: 表面中断, 由碰撞引起的下陷或凹痕.

Huoshan west-margin fault is perpendicular fault, and deeps down to the Moho discontinuity surface ( 38km).

For the position and the shape of slide surface, it deals with the method of cracks network simulating to count the parameters of discontinuity, and the combination of discontinuity and potential slide surface of the slope.

针对岩质边坡潜在滑面的位置及具体形态等问题，利用裂隙网络模拟的方法对各结构面进行统计，确定了边坡破坏的结构面组合模式以及潜在滑面位置。

SINK: Surface discontinuity, depression or dimple caused by non-uniform material shrinkage.

凹槽: 由材料收缩不一致引起的表面中断,下陷,凹洞.
