这个概念是，当被击中时，金属弹丸使两个带电板块撞起，形成一回电路和释放的电力脉冲，这可以打碎弹头了。

The idea is that when hit, the metal in a projectile shorts the two charged plates together, forming a circuit and releasing a surge of electricity which can break the warhead up.

电池放电时，正极释放出的锂离子快速运动回到负极，充电过程中在负极由锂离子携带的电子被释放出来，从而为外部电路提供电力。

As they do so, the electrons that were paired with them in the anode during the charging process are released. These electrons power an external circuit.

例如，放置活化材料的一层，当它被光照时，便会释放电子，而电路层则负责传送电子流。

For example, one layer contains the active material that releases an electron when it's struck by light and another layer contains the circuit that carries the current.
