例句
- The intergranular-type structure induced the transgranular fracture during loading,and the material was enhanced but fracture strength was poor due to grain-boundary sliding.
當受到外力時既能誘發穿晶斷裂，又能引起裂紋偏轉，起增強作用，但由於產生晶界滑移，材料韌性有所下降。 - The composite displays the fracture features of the dimple and intergranular fracture.
複合材料的斷裂形貌為韌窩加沿晶斷裂。
