结果表明，魏氏组织针由多个块状的亚晶粒组成，亚晶粒边界由位错缠结而成，在亚晶粒内有较高的位错密度；

The results show that Widmansttten structure needle consists of many blocky subgrains that have higher dislocation density and subgrain boundary is made up of dislocation tangle.

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。

With a continuously distributed dislocation model, this paper deals with cracks inclined to a free surface of a semi infinite plane under remote loadings.
