这对疏散星团位在英仙座内，距离我们约有七千光年远，因为肉眼就得见，所以远在西元前130年希腊天文学家伊巴谷斯就编录了它们。

Ten flyback flaps sized 3 cm×1.5 cm each was designed at the corpus' finger back with the pedicles at the distal end of fingers.The color changes of the flaps were macroscopically observed after the mixture of diatrizoate and Indian ink were infused into radical artery with pressure and the visualization of the blood vessels inside the flaps were observed radiologically.

在尸体手指背侧设计10个逆行皮瓣，蒂部在手指远端的一侧，皮瓣范围3 cm×1.5 cm，将泛影葡胺加墨汁加压注入桡动脉，肉眼观察皮瓣的颜色变化，X线造像观察皮瓣内血管显影情况。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
