裂纹骨折，破裂骨折

simple fracture───单纯骨折（断骨未刺穿皮肤）

hairline fracture───发丝状裂缝

closed fracture───闭合性骨折

fissure eruption───[地质]裂缝喷发；裂缝喷溢

refracture───n.骨再折术

simple fractures───单纯骨折（断骨未刺穿皮肤）

stress fracture───[外科]应力性骨折

Objective To show imaging findings of inferior orbital fissure(IOF)and groove(IOG)on axial CT scans and to discover their anatomic variations, so as to avoid misdiagnosing them as orbital fracture.───目的研究正常人眶下裂和眶下沟横断面CT表现及其解剖基础，避免将其误认为眶壁骨折。

mechanical property of N80 steel has increased obviously after adding corrosion inhibitor, where the ductility of N80 steel increased, and crack fissure of fracture surface decrease.───添加缓蚀剂后使N80试样的韧性有明显的增加，断口裂纹缝隙明显减小，力学性能有了明显的提高。

Because the process of rock broken is very complicated, there is a difference between the experimental data and theoretical result of expanding fissure by the present dynamic fracture theory.───由于岩石破碎过程非常复杂的，采用当前的动态断裂理论得出的裂纹扩展长度与实测值差异较大。
