At 200,000 kilometers down, we hit the radiative zone.

在 200，000 公里的地方，我们到达了辐区。

First, a photon enters the 185,000 mile-thick radiative zone.

首先，光子进入185000英里厚的辐区。

It's made possible by a phenomenon called radiative sky cooling.

是由“天空辐却”现象实现的可能性。

As heat leaves an object, it becomes cooler, a process known as radiative cooling.

热量离开物体时，物体会，一过程称为辐却。

His team built their device using an aluminum disk that acts as a radiative cooler.

他的团队用铝盘当作辐却器，制作出他们的设备。

So SkyCool designed a new material with radiative cooling properties that work 24 hours a day.

因此，SkyCool设计了一种具有辐却特性的新材料，可以24小时工作。

The radiative cooling, in the sense that we're doing, has really never been out there before.

辐却技术，像我们现在做的样，以前从未有人做过。

An important limitation of radiative cooling has long been its relative ineffectiveness by day.

长期以来，辐却的一个重要限制是它在白天相对无效。

Surrounding that is the radiative zone, followed by the convective zone, which extends all the way to the surface.

周围是辐区，然后是对流区， 一直延伸到地表。

Chambers built of these radiative materials sometimes include adsorbent inner surfaces to which water in the air readily sticks.

由些辐材料建造的腔室有时包括吸附剂内表面，空气中的水很容易粘附在其上。

Instead of traveling across the radiative zone and hitting your eye, the light waves slam into electrons and other particles in the plasma.

光波不会穿越辐区然后击中你的眼睛，而会撞上电子和等离子体中的其他颗粒。

Another challenge posed by radiative cooling systems is that water needs to be wiped off the surface of the collection chambers.

辐却系统带来的另一个挑战是需要擦去收集室表面的水。

You can see there's just a really stark contrast in -- in temperature between the surfaces that are -- these radiative cooling found and the roof of the building.

面板表面和建筑物房顶的温度之间对比非常鲜明。

A key way to do this is with radiative cooling, a phenomenon that occurs at night when certain materials (like aluminium) radiate enough heat to cool below the ambient temperature of their surroundings.

实现一目标的关键方法是辐却，是夜间发生的一种现象， 某些材料（如铝）辐出足够的热量， 使其却到周围环境温度以下。
