因此，即使没有任何工业上的热量产生，城市地区也往往比它周围的农村暖和。

Therefore, even without any industrial production of heat, an urban area tends to be warmer than the countryside that surrounds it.

所以任何用电器工作时都会有热量产生。

Therefore any electrical appliance will radiate heat during working.

在任何发生这种氧化的地方，总有热量产生。

Wherever this oxidation takes place, heat is always produced.

The heater is on, it's producing heat until a negative signal is registered, 'oh we've gone too high', and then it turns off.

加热器会开着,一直产生热量直到它得到一个关闭的信号,噢我们弄得太热了,然后就关闭了

So that's the important take-away message from this slide. If we think about these different types of lights, microwave light, if it's absorbed by a molecule, is a sufficient amount of frequency and energy to get those molecules to rotate. That, of course, generates heat, so that's how your microwaves work.

重要的信息，如果我们看看,这些不同种类的光，微波,如果被分子吸收，它的频率和能量可以,使分子转动,这当然的，会产生热量,这就是你们微波炉的工作原理。
