有耳状部的

The stereocilia of OHCs are extremely short. We can observe thephenomena of rupture and inosculation of stereocilia, which is alike senile deafness ofICR mouse. The OHCs bodies of bats have two leading characteristics. Firstly, theOHCs bodies are obviously short. The Deiters cell phalanges are of exaggerated, andthe cup formation of Deiters cell body enwrap the bottom of the OHCs.

蝙蝠耳蜗外毛细胞体，主要特征有两点：其一是细胞体明显短，三排Deiters细胞的指突明显与顶表面相连，而且毛细胞体基本被Deiters细胞的杯状膜包裹；其二是外毛细胞体在基底部呈烧瓶状，并不是一般哺乳类动物的试管样形态。

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

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

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。
