在试样表面有 很多形变孪晶(Deformation twins)产生(见图 4(a))，而 仅在边缘处有一些滑移带(Slip bands)出现(见图4(b))， 这表明在粗晶纯锌中和在锆晶体 [10] 中一样，孪晶在某 些情况下比滑移更容易形成。

The persistent slip bands were determined by the observations of the substructure near the surface of gear steels on fatigue load.
通过对在疲劳载荷作用下渗碳齿轮钢次表层亚结构的观察发现有持续滑移带形成。
The results show that the broken type is brittle rupture, there are slip bands, and the caused reason is the expanding of graphite.
结果发现因为石墨膨胀造成铜箔拉裂的为脆性断裂。且有滑移带。
In the as-quenched condition, straight slip bands and cross slip bands are shown on the surface of specimens after tensile stress has reached the yield stress;
随着时效时间的延长，拉伸断口逐渐由韧窝穿晶型向沿晶突脊型及沿晶韧窝型过渡。 在固溶状态下，当拉伸应力超过届服强度以后，出现平直滑移带及交叉滑移带；
