钻头

METHODS: After anaesthetized, rabbits were cut at the skin for 2 cm long at the crossing of skull center and posterior canthus, skull was exposed and periosteum was separated, then a round skull window with diameter of 0.5 cm was drilled at 0.5 cm left or to sagittal suture and 0.5 cm posterior to coronal suture, after that, 35 g/L rose Bengal was slowly injected from ear-edge vein in dosage of 1 mL/kg by once.

兔麻醉后，沿颅骨的中央与眼后角垂直交叉处纵行切开皮肤约2 cm，暴露颅骨，刮离骨膜，在矢状缝左侧外0.5 cm与冠状缝后0.5 cm处，用钻头直径0.5 cm的颅钻钻透颅骨，造成颅骨圆形洞窗，随即由耳缘静脉按1 mL/kg一次性缓慢注入35g/L四氯四碘荧光素钠盐。约3 min后用冷光源(波长540 nm，功率140 lx)对准颅骨洞窗，连续照射8 min后，缝合皮肤切口。

In the middle of the Gulf of Mexico, 400km (250 miles) from land, BP found oil after sinking a drill almost 1,300 metres — the height of Ben Nevis — to the sea bed and then another 9,400 metres into the earth's crust.

英国石油公司在远离陆地400公里的墨西哥湾的中部，把钻头放到1300米深的水底，然后再往下钻了9400米（相当于珠穆朗玛峰的高度），终于有了这个大发现。
