手術中發現顱底篩骨篩板處有骨折並硬腦膜裂開,及充滿氣體之大腦囊腫。 -
We present a rare case of a patient with a distal radioulnar joint ( druj ) dislocation, tear of the interosseous membrane ( iom ) and a fracture - dislocation of the radial head after trauma of the extended hand
摘要我們報告一稀少病例為手外張受傷情況下,造成遠端橈尺骨關節脫位,骨間膜撕裂合併橈骨頭骨折脫位。 -
The cracks extend along the matrix / strengthening - phases interfaces and form the cleavage steps and tear ridges. there appear some very small dimples on the fracture surfaces of the directionally solidified samples, which come from the nb - based solid solution particles in the big plates of the strengthening phases, but no dimples on the fracture surfaces of the as - cast sample. it can be concluded from above results that niobium - niobium silicide based in - situ composites ( rmics ) with a uniformly orientated microstructure can be produced by the ebfzm with high temperature gradient, and their mechanical properties can be increased
隨著抽拉速率的提高和硅化鈮強化相間距與尺度的減小,材料的室溫拉伸強度和斷裂韌性均有提高, _ b最高可達778 . 4mpa , k _ ( ic )達到了46 . 3mpa ? m ~ ( 1 / 2 ) ;試樣的拉伸斷口基本表現為脆性解理斷裂的花樣,裂紋沿基體強化相界面繞過強化相進行擴展,在裂紋擴展方向存在解理臺階,並形成撕裂棱。
