分子在外电场影响下,正、负电荷重心发生相对位移,使分子发生变形,产生的这种偶极叫诱导偶极,此过程称之为分子极化。μ诱导与电场强度E和分子变形性两因素有关。介质材料可以在高频电场的作用下发生分子极化现象,并按电场方向排列,因高频电场,以极快的速度改变方向,则介质材料,就会因介电损耗而发热。

就分子设备而言,分子极化性测量的范围涉及到电子与单个分子接触的相互作用。
In the case of molecular devices, polarizability measures the extent to which electrons of the contact interact with those of the single molecule.
本农用活性水泵的输出水含有分子极化了的活性水,该活性水浇灌农作物,有利于生长和高产。
The output water of the utility model contains the active water; the molecules of the active water are polarized. The active water irrigates crops, and is beneficial to the growth and the high yield.
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.
These are so-called homo-polar molecules.
这就是所谓的均匀极化的分子。
