China will help foreign trade enterprises through current challenges and maintain steady and high-quality growth of the sector to stabilize the economy, industry chains and supply chains, according to a circular released by the State Council on May 26.

5 月 26 日，国务院办公厅印发《关于推动外贸保稳提质意见》，帮扶外贸企业应对困难挑战，实现进出口保稳提质任务目标，助力稳经济稳产业链供应链。

So pacemaker cells are, in a way, your heart's very own brain, generating the initial spark that sends a current through your heart's internal wiring system, known as the intrinsic cardiac conduction system.

所以起搏细胞在某种程度上是心脏自己大脑，产生最初火花，通过心脏内部线路系统发送电，为内在心脏传导系统。

Researchers at Oxford University studied 15 student volunteers and found that passing a current through a specific brain region and in a particular direction improved performance in maths puzzles.

牛津大学研究人员对15名学生志愿者进行了研究，发现对大脑某个特定区域以特定方向通电可以提高学生在数学语方面表现。

Washington does not want Europe to increase its reliance on Russian gas, especially not by undercutting current transit routes through Poland and Ukraine.

华盛顿不希望欧洲增加对俄罗斯天然气依赖，尤其是不能通过削减现存通过波兰和乌克兰运输管道来实现。

The new method involves passing a current through a molten pool of iron oxide, which drives off the originally sought-after oxygen.

新方法骤则包括向熔炉里氧化铁通电，从而释放原本就炙手可热氧气。

That way, at least you’re not actively sending a current through all that circuitry.

这样， 至少您不会主动通过所有电路发送电。

I was looking through current political cartoons, and this guy kept coming up.

我在浏览当前政治漫画时，这个家伙经常出现。

750 amps of current cut through this like butter.

- 750安培电像切黄油一样轻松穿过这里。

Inventing a viable electric light was hard, I mean, this is the typical incandescent design, which just involves passing electric current through a material making it so hot that it glows, less than 5% of the electrical energy comes out as light.

发明一种可行电灯是很困难, 我意思是, 这是典型白炽灯设计, 只需让电通过某种材料，使其变得非常热，从而发光，只有不到5%电能以光形式出现。

Naturally occurring magnets aren't powerful enough to lift up huge slabs of steel, but wrap an iron core with wires and run a current through and voila, you can create a powerful electromagnet that can lift cars.

自然产生磁铁不足以举起巨大钢板，但用电线包裹铁芯并让电通过， 瞧，你可以制造一个可以举起汽车强大电磁铁。

Sure, and as it happens, my biological sister, who lives in the States, lives in Colorado, has met her current boyfriend through online dating, and they've been together for several years now, in fact, and they're quite happy together.

当然，巧是，我亲妹妹住在美国，具体在科罗拉多州，她就是通过网络交友认识了现在男朋友，他们在一起已经好几年了，实际上，他们非常幸福。

Thus creating a potential difference between the cylinders which could be harnessed to drive a current through an external circuit In effect and at an extremely small scale.

从而在两个圆筒之间产生电位差，可以利用这一点来驱动电通过外部电路，实际上是在极小尺度上实现。

And if you try and pass more current than that through the material, it's going to become a resistive material, a normal material.

而且， 如果你试图让材料通过电超过这个限度，它就会变成一种有电阻普通材料。

If you want to find the current through each branch, and the voltage drop across each resistor, you’re gonna need Gustav’s help!

如果你想找到通过每个分支电， 以及每个电阻器上电压降， 你将需要 Gustav 帮助！

If you want to find the current through each branch, and the voltage drop across each resistor, you're gonna need Gustav's help!

如果您想找到通过每个分支电，以及每个电阻器上电压降，您将需要 Gustav 帮助！

And when you run a current through that wire, it creates a magnetic field.

当你通过那根导线通电时，它会生成一个磁场。

And the drop across resistor 1 in the same loop would be the resistance, 40 Ohms, times the current through the resistor, which is 0.375 Amperes.

同一环路中电阻 1 上压降将是电阻 40 欧姆乘以通过电阻电，即 0。375 安培。

Then, he runs the current through the wire in the opposite direction, and sees the needle move the other way.

然后，他使电以相反方向过电线，并看到针向另一个方向移动。

Since you know the resistance of, and voltage across, each resistor, you just use Ohm's Law again to calculate the current through each wire.

因为您知道每个电阻器电阻和电压，所以您再次使用欧姆定律来计算通过每条导线电。

He took two parallel wires, ran a current through both of them in the same direction, and the wires attracted each other!

他拿了两根平行线，把它们都转向同一个方向，线就互相吸引了！
