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

在 200，000 公里地方，我到达了辐射区。

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

首先，光子进入185000英里厚辐射区。

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

这是由“天空辐射冷却”现象实现可能性。

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

热量离开物体时，物体会变冷，这一过程称为辐射冷却。

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

团队用铝盘当作辐射冷却器，制作出设备。

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

因此，SkyCool设计了一种具有辐射冷却特性新材料，可以24小时工作。

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

辐射冷却技术，像我现在做这样，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，辐射冷却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.

周围是辐射区，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.

由这些辐射材料建造腔室有时包括吸附剂内表面，空气中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.

光波不会穿越辐射区然后击中你眼睛，而会撞上电子和等离子体中其颗粒。

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

辐射冷却系统带来另一个挑战是需要擦去收室表面水。

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.

实现这一目标关键方法是辐射冷却，这是夜间发生一种现象， 某些材料（如铝）辐射出足够热量， 使其冷却到周围环境温度以下。

Not just a ball of hot gas At the centre of the Sun is a core in which nuclear fusion takes place; surrounding that is the " radiative zone" where energy is transported via radiation and thermal conduction.

不仅仅是一个热气球在太阳中心是一个核聚变发生核心；周围是“辐射区” ，能量通过辐射和热传导传输。
