介电常量介电常量Dielectric constant 来定义:(l)究时所用的频率范围。对低于10，赫左右的频率，插人一平行板电容器中的电介质样品的电容率或阻抗，可以用一些适当电路来测量:谢灵(Schering)电桥的装置常用于直到1护赫的范围，而谐振电路则常用于1少一1护赫的范围。对于105赫以上的频率，介电常量可通过测量电磁波与该介质的相互作用来确定。在大约10“至1011赫的范围内，材料往往充填于波导或同轴电缆之中，然后量度其各种驻波波型。在更高的频率下，就要用到包括反射和透射测量在内的光学技术。在分析化学中所用的测量技术将在下面讨论。 宏观理论下式的介电常量K是一个把电位移矢量D、极化强度p和电场E这些宏观量联系起来的无量纲参数:c一C0 一一 佑1+器一‘+yx，‘2， 一一D一e0E 一一.一气 一一这里C为充满了电介质的电容器的电容，而C。为真空电容器的电容。 介电常量‘也称为电容率(speeifie induetiveeapaeity)或相对电容率(relative permittivity)。它作为静电学库仑定律中的一个比例常量，也许最为人们所熟悉。对于某一给定电荷分布，介电常量表示真空中的电场强度与电介质中的电场强度之比，后一个场由于电介质的极化而被削弱。参阅“库仑定律”( Coulomb’5 law)、“电介质”(dieleetries)、“电场”(eleetrie field)和“电容率”(permittivity)各条。 对于低频或静态场，典型电介质的‘值范围从1至10000以上。气体的介电常量仅比1稍为大一点，而高K值则出现在许多极性液体和某些离子固体中。附表列出了一些具有代表性的电介质材料的介电常量。
