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

它不是单一的辐射热测定器，而是大量的辐射热测定器。

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

这使它们能够看到乳动物的辐射热。

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

辐射热测定器的电于它的热度。

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

这些仪器，技术上称为现场高计，使用一种称为辐射热测定器的设备来估计一个物体的度。

You can also lose heat through radiation.

热度。你也可以输 辐射热。

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辐射热。

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辐射热。
