Ion channels sit in a cell's outer membrane and let electrically charged atoms (ions, as they are known in chemical jargon) in and out of the cell.

离子通道位于细胞外膜，使带电荷原子(即化学术语中的离子)可以进出细胞。

Another source of information is genetic. Long QT syndrome is caused by defects in ion channels, proteins that maintain heartbeat by controlling the flow of ions across the membrane of heart cells.

长qt综合征的另一个来源是遗传，长qt综合症是由离子通道的变异引起的，蛋白质通过控制离子流经细胞薄膜来维持心跳。

The holograms were fabricated using a very finely focused ion beam to cut a pattern of extremely small slits just 20 nm across through a thin silicon membrane 30 nm thick.

全息图是用精细聚焦的离子束在一片30 n m厚的薄硅膜上切割出20nm长的极小的裂纹的图案组合而成的。

It would generate an electrical signal because it would - you'd open the ion channel and you would ion fluxes and you would change the membrane potential in just the way I described for the action potential.

它会产生一个电信号,因为--,离子通道会打开,产生离子流,膜电位会改变,像我讲动作电位时那样
