A lithium-ion battery generates energy by moving lithium ions from one electrode to the other, drawing electrons, and thus electrical current, through an external circuit and powering our devices.

锂离子电池通过锂离子从一个电极移动到另一个电极产生能量，移动电子，就产生电流，连接到外部电路就能为设备提供电能。

This moving sea is a big part of what makes metals… metal.

这种移动电子海是金属重要组成部分。

Now e mail and cell phones are rapidly replacing the old forms of communication.

现在电子邮件和移动电话正在迅速取代旧通讯方式。

The spinning magnet causes electrons to move in the wires and produce an electrical current.

磁铁使电子在导线中移动并产生电流。

Philo knew electrons could be made to move very fast.

菲罗道电子以移动得非常快。

It consisted of fast-moving electrons, situated between the two previously known Van Allen Belts.

它由快速移动电子组成，位于已为人们所两个范艾伦带之间。

The 63-year-old was in charge of Samsung's consumer electronics and mobile devices division.

现年 63 岁他负责三星消费电子和移动设备部门。

However, China has been and is paving the way in social media, e-commerce, and mobile payments, and the rest of the world is following.

然而，中国社交媒体、电子商务和移动支付建设已经颇具规模，且仍在不断发展壮大，其他国家也正紧随其后。

The system that came from their work creates light that shows the fast-moving electron in its orbit around the nucleus.

他们研制系统所产生光显示出原子核周围轨道上快速移动电子。

Patrick has tried to force one of those cell phone camera things on Ove, but he doesn't trust them.

帕特里克想给他装个什么电子移动相册，但欧维信不过这种东西。

These can be used to study the rapid processes that can take place when electrons move or change energy.

阿秒光脉冲用于测量电子移动或能量变化快速过程。

When a bunch of metal atoms come together in a chunk, these outer electrons wiggle free, creating what scientists usually think of as a negatively-charged “sea of electrons” flowing around a network of positively-charged ions.

当大量金属原子聚集结合为块状，这些外层电子自由移动，就产生了科学家通常所说电子海，即大量带负电荷电子游荡在带正电金属阳离子周围。

The electrons that move along an alternating current, on the other hand, periodically and consistently change direction.

另一方面，在交流电中移动电子会周期性地、持续地改变方向。

Then, that electron moves around the crystal lattice until it settles into a defect.

接着，该电子在晶格中移动，直到融入晶格缺陷中。

Electric current, anything from static electricity to lightning bolts, is electrons moving from negative to positive.

从静电到闪电任何电流都是电子从负向正移动。

That's because depending on the metal, the sea of electrons will have a different mass and density, which affects how freely the electrons can move — and therefore, whether they can vibrate to match the incoming wave.

这很大程度上取决于金属本身，电子海具有不同质量及密度，它们影响着电子自由移动程度，以及它们振荡是否能够产生见光。

Maybe, instead, the electrons themselves were being moved around.

相反，也许电子本身在四处移动。

For example, you can hammer them into different shapes without cracking them because the electrons can move to compensate for the atomic nuclei shifting around.

比如，它们以被捶打成各种形状而不会断裂，这是因为这些电子以移动去填补向四周移原子核位置。

And for electrons to start moving, they need to have the right amount of energy to leave their parent atoms and join what's basically a sea of moving electrons.

要让电子开始移动，它们需要具备足够能量以离开其所属原子，并融入大量自由移动电子。

If the photon has less energy than the work function, the electron won’t go anywhere.

如果光子能量小于逸出功，电子就不会移动。
