That results in a dramatic change in the membrane voltage; the potential across the membrane and that's shown here by this rapid rise in membrane potential.

变化导致了膜电压的剧烈变化,膜电压就是跨膜的电势差,表现为膜电位的迅速上升

That happens, and if I was looking at a region of membrane that was experiencing an action potential I would see voltage change in just the way it's shown in this graph here.

当去极化发生时,如果我观察一个经历动作电位的区域,我就会看到这样的电压变化,就像这幅图上展示的一样
