However, when that gate is opened, the sodium channel is now going to be incredibly selective and only let through sodium ions and no other type of ion.

但是，当闸门打开的时候，钠离子通道,将会有极高的选择性,不允许除钠离子以外的任何其它离子通过。

So the influx of ions from the outside of the cell to the inside of And you can think of ion channels as being gated, by gated it means the gate can be closed and no ions are going through, as in this case here.

下面以离子从细胞外部流入内部,你可以把离子通道想象成是有闸门的，也就是说闸门可以关上,这时没有离子能通过，就像这种情况。
