实际由液晶分子组成的LCD显示屏也采用了百叶窗，分子的极化转变可阻挡光或让其通过。

LCD displays also use shutters, in effect, consisting of liquid-crystal elements whose polarisation can be changed to block light or let it pass.

显然，氦的可极化电子云最小。

Clearly, helium has the least polarizable electron cloud.

与此相对，氙具有高度可极化性，所以有很高的溶解性，是一种很好的麻醉剂。

In contrast, highly polarizable xenon has high solubility and is an excellent anesthetic.
