The fracture mechanism of TWIP steel (steel1#) which contained second phase was that the microvoids nucleated due to the decreasing of binding force between austenite and second-phase or the second phase dehiscence caused by strain hardening, then the microvoids grew, got together and broke by the stress concentration during deformation.

含有第二相的TWIP钢（1＃钢）的断裂机制为：第二相和奥氏体相界面聚合力的减弱或第二相本身加工硬化导致的开裂促使微孔形核，形变过程中产生的应力集中使微孔长大、聚合直至发生断裂。

The fracture mechanism of TWIP steel (steel1#) which contains second-phase is: micro-voids nucleate due to binding force weaken between austenite and second-phase or second-phase dehiscence itself caused by strain-hardening. Micro-voids are formation, growth, coalescence and break by the stress concentration during deformation.

含有第二相的TWIP钢（如1＃钢）的断裂机制为：第二相和奥氏体相界面聚合力的减弱或第二相本身加工硬化导致的开裂促使微孔形核，形变过程中产生的应力集中使微孔长大、聚合直至发生断裂。

Results:①The center of the homogeneous density soft tissue masses (mean CT value was 50HU) were located in the middle and lower tympanum,and the external auditory canal or the pharyngotympanic tube was involved in the earlier period;②the destructed b...

结果：中耳癌的CT特征：①表现为以中、下鼓室为中心的软组织密度灶，密度均匀，CT值50HU左右，外耳道及咽鼓管早期受累；②呈溶骨性骨质破坏，形态不规则，边缘无骨硬化表现，外耳道后壁破坏较前壁严重；③病灶侵入颞叶，形成肿块，灶周脑水肿不明显；④增强扫描见病灶有中度强化。结论：CT能确定中耳癌的存在及精确显示肿瘤累及范围。
