A battery is made of two electrodes connected to a circuit and separated by an electrolyte.

电池由电路连接两个电极组成，并由电解液隔离开。

Electric chemical cells, also called batteries, require three things: two electrodes and one electrolyte.

电化学电池，也被称为电池，需要三个元素：两个电极和一种电解质。

To give users a sense of taste, researchers designed two electrodes that are placed on the tongue.

为了给用户带来味觉，研究人员设计了能放置在舌头上的两个电极。

If enough electricity is created, the air between the two electrodes can produce enough thrust to power a small aircraft.

如果电力足够，那电极之间的空气就可以产生足够的推力来推进小型飞机。

Graduate student Xiaomeng Liu then applied a voltage between the two electrodes.

研究生刘晓萌随后在两个电极之间施加了电压。

Its early form, the diode, consisted of two electrodes in an evacuated glass container.

它的早期形式是二极管，由真空玻璃容器中的两个电极组成。

When the two electrodes are connected, current begins to flow.

当两个电极连接时，电流开始流动。

Typically, transistors have two electrodes separated by a material that sometimes can conduct electricity, and other times resist it – a semiconductor.

通常来说，晶体管有导电材料隔开的两个电极这些材料，有时导电，有时却不导电——这就是半导体。

Luckily, shortly after, in 1906, American inventor Lee de Forest added a third " control" electrode that sits between the two electrodes in Fleming's design.

幸运的是，不久之后的 1906 年，美国发明家李·德富雷斯特参考弗莱明的设计，在两个电极间加入了第三个" 控制" 电极。

A new arc will then be generated at the shortest distance between the two electrodes, creating a stable region of discharged plasma.

然后新的电弧将在两电极距离最短处产生，形成稳定的放电等离子区域。

Now, in addition to these three limb leads, there are also bipolar limb leads called lead I, II, and III, which are recorded using two electrodes instead of just one.

同时，除了这三个单极肢体导联，还有3个双极肢体导联，分别称为I导联、II导联和III导联，它们是用两个电极而非一个电极来记录的。

In 1904, English physicist John Ambrose Fleming developed a new electrical component called a thermionic valve, which housed two electrodes inside an airtight glass bulb - this was the first vacuum tube.

1904 年英国物理学家约翰·安布罗斯·弗莱明开发了一种全新的电子部件叫" 热电子管" ，就是在一个密封玻璃灯泡里放了 2 个电极——这是世上第一个真空管。

The dye molecules themselves are bound to tiny particles of titanium dioxide, a less-famous (but cheaper) semiconductor than silicon, and the whole assembly is immersed in an electrolyte and sandwiched between two electrodes.

染料分子自身会与二氧化钛（一种不如硅名气大，但比硅便宜的半导体）的细小微粒相结合，然后整个装置会浸没于一种电解质里并夹于两个电极之间。

She's staring up at the electric light - it's an  arc lamp, a wisp of lightning crackling between two electrodes. She's listening to the hiss,   noticing that when the ark buzzes, the light dims.

她抬头盯着电灯——这是一盏弧光灯， 一缕闪电在两个电极之间噼啪作响。她正在聆听嘶嘶声， 注意到当方舟发出嗡嗡声时， 灯光会变暗。
