Imaging with scanning transmission electron microscopy showed that the atomic grain-boundary structure had dislocations that had very similar arrangement.
扫描电子显微镜图像显示这两种晶界原子结构中的位错排列十分相似。

Diffusion of oxygen in the bonding coating and substrate is mainly grain-boundary diffusion. Grain-boundary diffusion coefficient is far greater than intragrain diffusion.
氧在粘结底层和基体中的扩散是以晶界扩散为主，晶界扩散系数远远大于晶内的扩散系数。

The individual crystal units comprising the aggregate structure where the crystalline orientation does not change. The grainboundary is where these individual crystal units meet.
