在中叠体阶层施以去大脑手术，分别比较於少量麻醉药影响下，去大脑手术前后心脏血管参数改变现象，结果显示，去大脑后常态动脉血压显著降低，但是对於背延脑及腹侧延脑的升压反应并无明显的改变。

A meso mechanical analysis has been conducted on a hot-rolling steel of 16MnR toinvestigate the effect of the elongated pre-damage voids on the subsequent damage evolution and fracture process under the maximum normal stresses with various directions. The analysis results show that, when the elongated voids due to the decohesion of the inclusions from base material are loaded subsequently, the local high stress and strain concentration around the voids and their interactions promote the growth of voids.

对热轧钢中的长条形初始损伤孔洞承受不同方向最大正应力时的后续损伤演化和断裂过程的细观有限元力学分析研究表明：热轧钢中的长条形夹杂物与基体剥离后形成的长条形孔洞在后续加载中，其周围产生的局部高应力应变集中及其相互作用，使孔洞长大。
