 外刊例句 

And the way this is done is that there are so called hair cells...these cells have little microscopic bristles, about a hundred of them, and on the top of each cell, these bristles vibrate back and forth in response to sound. That sets up an electrical signal that then goes down a nerve fiber and into the brain.

转化通过所谓的毛细胞来实现。这些细胞顶部有极小的毛，大约有100根，这些毛会随着声音来回振动。这会产生一个电信号，之后电信号会沿着神经纤维进入大脑。
