这就是为什么它能打开和关闭通道，从而引起位移的原因。

That is why it can open and close the channel, thus leading to displacement of reasons.

用户端会在收到用户端可以关闭通道的认可之前收到通知。

The client receives the notification prior to the acknowledgment that the client can close the channel.

当关闭通道时，用阀杆的楔形头使球体涨开与阀座压紧达到密封。

When the closed channel, the wedge-shaped head with a stem to open up the ball and pressed to seal the valve seat.

It has a gate on it and that gate is in open or close state depending on whether a ligand is present or not.

在这个通道上有个门,这个门是打开还是关闭,取决于配体到来与否

So, for example, if we look at sodium channels, and sodium channels are some of the particularly prevalent ones when we're talking about neurons, if you think about the cell membrane, and this little green cartoon is me trying to show a sodium channel here, and in this case, you can see that it's closed, such that no ions are getting through.

比如，让我们来看一下钠离子通道，钠离子通道是我们会经常遇到的几个之一,在讨论神经元的时候，如果大家想想细胞膜，而这个绿色的小示意图就是我用来表示,钠离子通道的，在这种情况下，大家可以看到它是关闭的，因此没有离子可以通过。
