Strong connections, with lots of ion flow, indicated that social experiences were rewarding.

离子流多的强力连接表明社会经验是有益的。

Conversely, weak connections (those with little ion flow) indicated that social experiences were not triggering a reward.

相反，连接薄弱（离子流较少）表明社会经历没有触发奖励。

Positively charged ions flow back in.

带正电的离子流回。

That, though, happens only when the ion flow is balanced by a flow of electrons through an external circuit between the electrodes.

然而，只有当离子流被通过电极之间外部回路的电子流平衡时，这种情况才会发生。

These pores let sodium ions flow into cells, and in taste cells, the incoming sodium ultimately sends a signal to the brain.

这些孔会让钠离子流入细胞，在味觉细胞中，进入的钠最终会向大脑发送信号。

The chemical reactions inside a battery generate electrical energy, as electrons or ions flow from one electrode to the other A lithium-ion battery, specifically, is a rechargeable battery that can be really compact.

电池内部的化学反应会产生电能。 当电子或离子从一个电极流向另一个电极时，具体而言， 锂离子电池是一种非常紧凑的可充电电池。

Its cathode is made from a lithium metal oxide and its anode is made of graphite, and they’re kept apart by a thin polymer separator that still lets lithium ions flow back and forth.

它的阴极由锂金属氧化物制成， 阳极由石墨制成，它们由薄聚合物隔板隔开， 仍然可以让锂离子来回流动。
