Okay, how do you prevent eddy currents in a transformer?

你如何预防变压器的损耗？

Tapering a building as it rises also breaks up the uniformity that causes vortex shedding.

建筑物在上升过程逐渐变细，也打破了导致脱落的建筑物均匀性。

They swim up to the ocean surface to poo, and this poo can be spread in an eddy – a large current of water moving in a circular motion, like a giant whirlpool.

它们游到海面上排泄，而这些排泄物会在散开来——大量水做圆周运动形成，就像一个巨大的漩。

And today's super-skinny skyscrapers have to deal with a particular wind-induced phenomenon called vortex shedding.

今天的超薄摩天大楼不得不应对一种特殊的由风引起的现象，称为脱落。

This is a mathematical transformation where we create a sphere, and a set of points on this sphere correspond to vortex lines and their evolution over time.

我们在这个数学变换创造一个体，体上的一系列点与线及其演变相符。

This forms a low pressure system and Wang says when it moves south, it pushes the polar jet stream off its normal course and forms a second vortex.

这形成了低压系统，而王海龙说当它向南移动时，会推动基地喷射偏离正常轨道，继而形成第二个。

It turns out that a vortex, a local spinning region in a fluid, can persist if the fluid in which it's embedded is itself rotating.

原来是一个，体的局部旋转的区域，只要它所嵌入的体本身在旋转，那么它就会持续存在。

As I drifted between the trees, surrounded by the chatter of the forest, swirling waves of pink and purple engulfed me.

当我在树木间漂时，四周都是森林的喧闹声，粉红色和紫色的将我环绕。

In other words, big eddies transfer their energy to smaller eddies, which do likewise at other scales.

也就是说，大的会把能量传给小的，后者只是前者的缩小版。

With every floor offset to the last, the number of " bluff" areas across these structures is considerably reduced, minimising - or in some cases completely eliminating - the locations where vortices can form.

每一楼层都与上一层互相抵消，这些建筑物的 " 悬崖 " 区域的数量大大减少，减少到最低限度--或在某些情况下完全消除--可能形成的位置。

They avoid obstacles, effortlessly slalom between vortices or whirlpools, and hide from predators—even when they can't see.

它们能避开障碍物，不费吹灰之力的游走在间，还能躲过掠食者的追踪—这都是在看不见的情况下完成。

Good initial results were repeated by a larger working model called Vortex installed in a nearby field.

他们随后在附近地区建造了名为的更大工作模型进行重复试验得到结果很是理想。

An eddy is a large current of water moving in a circular motion.

是指做圆周运动的大量水。

Those are essentially whirls of air.

本质上是空气的漩。

This high pressure system is a clockwise spinning vortex.

这一高压系统是顺时针旋转的旋转。

It did something similar, but instead of using AI, it used some heuristics that describe what is the ratio and distribution of smaller and bigger vortices in a piece of fluid or smoke.

它并没有使用AI来完成类似的事情，而是使用启发法来描绘出一个体或烟雾较小和较大的比例和分布。

This happens when wind flowing past a building creates vortices, strong swirls of air that magnify the damaging effects of wind.

当风吹过建筑物时就会产生，这种强烈的会放大风的破坏效果。

In low winds, these vortices cancel each other out.

在低风，这些相互抵消。

Turbulence in the regions between zones and belts can create storms, gigantic vortices raging in the clouds.

在区和地之间的会形成风暴或云团的巨型旋。

Aluminium can be separated from the plastic using a machine called an " Eddy Current Separator" .

铝可以用一种叫做“分离器”的机械装置从塑料被分拣出来。
