Methods The serial sheet transverse sections of the superior orbital fissure region obtained using collodion microtomy in 5 adult cadaver heads were observed .

方法采用火棉胶切片技术对5例（10侧）眶上 裂区标本连续薄层 横断层切片进行解剖学观察。

The phenomenon of longitudinal fission seldom occurred during the process of tube plug drawing mill compared with empty-sunken steel tube . The problem which seldom cause transverse fissure in form of partial failure owing to uniform distribution of axial stress in cross section .

与空拔相比较，在短芯棒拔制过程中，纵裂现象一般不会发生，由于钢管轴向应力在横截面上分布均匀，一般也不会出现以局部破坏形式出现的 横 裂现象。

Test group sphincter longitudinal line transverse joint operation ; control group anal fissure excision incision and the sphincter is not special treatment open drainage .

试验组行内括约肌纵切 横缝术；对照组行 肛裂切除术，切口及括约肌不予特殊处理，敞开引流。
