With a continuously distributed dislocation model, this paper deals with cracks inclined to a free surface of a semi infinite plane under remote loadings.
采用连续分布位错模型讨论和分析了受远处载荷下半无限平面自由边界附近任意方位的裂纹问题。

These negative dislocations seem to enter the crack tip and blunt it, resulting in a dislocation-free zone at the crack tip.
这些负号位错将移至裂纹顶端并使之钝化而留下一个无位错区或低位错密度区。

In this paper, oxygen precipitates and induced defects in annealed dislocation-free CZ-Si with high oxygen content have been investigated by HVEM.
