双语例句
1
Crack propagation is affected by many factors, among which, the cracktipplasticzone attracts a lot of attention.
影响裂纹扩展的因素有许多，这其中，裂纹尖端塑性区引起众多研究者的兴趣。
2
The dislocation distribution function in the plasticzone at a cracktip is calculated with the help of a modified BCS-type crack model.
本文改进BCS型裂纹位错模型，并对裂纹顶端范性区的位错密度分布进行了计算。
3
Pure elastic fracture is always rare, so th at under the action of stress, a plasticzone(large or small), and interactions between crack and dislocations always exist at the crack tip.
