When one of the dye molecules is hit by light of sufficient energy, an electron is knocked out of it and absorbed by the titanium dioxide, before being passed out of the cell to do useful work.

一旦染料分子被有足够能量的光碰触，电子就会脱离并被二氧化钛吸收，在穿离电池之前发电。

But even a light wind causes it to tremble and totter, and all the braces are not sufficient to make it secure. So I am getting ready to move.

但是如今一阵微风就够叫它摇动震颤，所以我不能不预备迁居了。

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。

According to Bijou Bob's official weblog, PBS has given "the green light" to producers to revive some of the greatest 'toons of the past, and just as soon as sufficient sponsors are found, you can expect to see the renditions in stunning HD, which will likely prove that Betty Boop actually is forever young.
