单晶形状和尺寸的塑性变化在宏观上被看作是薄层的相对位移，这类似于一叠卡片的位移。这种宏观层面的划分发生在拉伸时（图1），也发生在对压缩、弯曲、扭转和剪切的响应时。这种类型的滑移总是发生在塑性变形的工业金属、岩石或其他多晶合金材料的晶粒内;在抛光的切片中可以看到，它是具有几个方向的特征条纹（图2）。
Plastic alteration of the shape and dimensions of a monocrystal is seen macroscopically as the relative displacement of thin layers, which resembles the displacement of cards in a pack. This division into macroscopic layers occurs in tension (Fig. 1) and also in response to compression, bending, torsion, and shear. This type of slip always occurs within the grains in a plastically deformed technical metal, rock, or other polycrystalline material; it is seen in polished sections as characteristic streaks with perhaps several directions (Fig. 2).
