This is structure to structure fire spread, both radiant heat, ember cast that really show the power of what fire can do.

这是建筑物间火势蔓延，包括热和飞火，它们真实展现了火灾破坏力。

This allows them to see the radiated heat of warm-blooded mammals.

这使它们能够看到温血哺乳动物热。

Thermal lift is caused by radiant heat coming from the ground, and dynamic lift is created as wind flows over hills and mountains.

热升力是由地面发出热引起，而动力升力则是在风吹过山和山脉时形成。

These instruments, known technically as spot pyrometers, use a device called a bolometer to estimate an object's temperature.

这些仪，上称为现场高温计，使用一种称为热测定设备来估计一个物体温度。

A bolometer's electrical resistance depends on how hot it is.

热测定电阻取决于它热度。

Instead of a single bolometer, it has an array of them.

它不是单一热测定，而是大量热测定。

The chambers let radiant heat spread the heat evenly so electricity can heat thousands of tons of brick to thousands of degrees, safely and evenly.

这些腔室让热均匀扩散，从而使电力能够安全且均匀地将数千吨砖加热到数千度。

And doing so in the microwave region with detectors not made of biological human retina cells, but of superconductors and things called bolometers.

在微波波段进行探测，所用探测并非由生物人眼视网膜细胞构成，而是由超导体和一种名为测热计装置制成。

On paper, neither molecule looks lopsided, so it doesn’t seem like they should be able to absorb any radiating heat.

在纸面上，这两个分子看起来都不平衡，因此它们似乎不应该能够吸收任何热。

You can also lose heat through radiation.

热度。你也可以输 热。

But then it turns out it was actually radiant heat that was more likely the culprit.

但后来事实证明，罪魁祸首更有可能是热。
