angular surface

Application of the fully mechanized longwall sub-level caving technology in the large-angle angular surface mining

综放技术在大倾角俯斜开采中的应用

Shape features of coarse aggregates include contour shape, angular features and surface texture. Contour shape represents the overall shape ratio of a particle, angular feature is the prominent degree of the angular on the profile, and texture describes the surface roughness of a particle.

粗集料形态特征包括轮廓形状，棱角特征和表面纹理，轮廓形状表征的是颗粒的整体形状尺寸比例，棱角性表征的是颗粒轮廓上棱角的突出程度，纹理描述的是颗粒表面的粗糙度。

The angular distribution and the spatial density distribution of the backscattered electrons on the film surface are also calculated.

计算了背散射电子角分布和空间密度分布。

The angular displacement of reflecting surface is measured in accordance with the direction change of Moire fringes caused by the inclination of grating. self-imaging plane.
