Doubling the frequency of logical operations inside a microprocessor doubles the heat output.

微处理器内部逻辑操作的频率加倍，产生的热量也加倍。

The crystals work by manipulating phonons, or vibrational waves that can carry either sound or heat depending on the frequency.

这些晶体通过对声子进行操控来工作；声子是一种振动波，可以携带声音或热量，具体携带什么则取决于其频率的高低【 译者注：声子是晶体点阵振动能的量子 】。

The warming of the planet will be gradual, but the increasing frequency and severity of extreme weather events, like intense storms, heat waves, droughts, and floods, will be abrupt and acutely felt.

地球将逐渐变暖，剧烈风暴、热浪、干旱和水灾等极端气候事件将日益频繁和严重，令人措手不及，造成极为严重的影响。

Then they use radio frequency energy to heat the tissue around the catheter.

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。

McDonald was also the third physician in the world to perform a procedure called conductive keratoplasty -- a noninvasive surgery for farsightedness that involves using radio-frequency energy to heat small spots around the cornea.

Then, the waves' frequency is tweaked and the sample blasted head-on in order to heat it.

Record high temperatures are occurring with far greater frequency than in decades past, and crop yields decline sharply in extreme heat.
