结构直径 meaning in Chinese

constructed diameter

In the relatively high dislocation density areas , dislocations form the relatively small cellular structure and there is few isolated dislocation within each cellular structure . here the profile of c concentration in the dimension of a cellular structure is " u " - shaped . the cell diameter increases as the dislocation density decreases , dislocations form the relatively large cellular structure and there are a few isolated dislocations within each cellular structure
发现晶片中位错密度和分布严重影响碳的微区分布，高密度位错区，位错形成较小的胞状结构，胞内无孤立位错，碳在单个胞内呈u型分布；较低密度位错区，胞状结构直径较大，胞内存在孤立位错，碳在单个胞内呈w型分布。
