As the grain size decreases, there is a significant increase in the volume fraction of grain boundaries or interfaces.
当晶粒尺寸减少时，晶粒边界或界面的体积分数有很大的增加。
It is evident that the effects of strain-induced recrystallization on grain refining and on high-angle grain boundary fraction increasing affect greatly the superplastic properties of the alloy.
研究指出，应变诱发再结晶对细化晶粒和提高大角度晶界分数的作用明显地影响合金的超塑性能。
In addition, with the increasing distance between the filament and the substrate, the crystalline volume fraction and the grain size of poly-Si films notablely decrease.
另外，随着热丝与衬底间距的增大，沉积出的多晶硅薄膜样品的晶化率明显减小，薄膜的晶粒尺寸也相应减小。
