When a voltage is applied across two beamlike electrodes made of aluminium, which are separated by a gap of around 50 nanometres, charge builds up on each, creating an attractive force between them, until a critical point is reached.

柱状的铝电极间隔约50纳米,当电压加在
两
电极之间时,它们就会相互通电,在二者之间会形成
股引力,直至达到
临界点。
Medications like lidocaine or Xylocaine, which you typically get at the dentist or for some minor procedures, basically block the opening of voltage-gated sodium ions, which means that you can't really have those action potentials spread.
像利多卡因或昔洛卡因
样的药物,通常会在牙医那里或
些小手术中使用到,基本上阻止了电压门控钠离子的开放,
意味着你无法让动作电位扩散。
