relative permittivity和dielectric constant在本质上都是描述材料电学性能的参数，但在应用和计算上存在一定差异。详细解释：1. 定义与性质 relative permittivity，即相对介电常数，是描述电介质材料对电场响应能力的物理量。它是电介质材料极化程度的一种量度。介电常数则是用来表示绝缘材料电容特性的一个参数...
relative permittivity是相对介电常数εr dielectric constant是真空的介电常数ε0，也可以写成vacuum permittivity 物质的介电常数permittivity，也就是εs=εr·ε0
Common materials and their relative permittivity. The dielectric constant - also called the relative permittivity indicates how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of "the permittivity of a substance to the ...

The dielectric constant (or relative permittivity) of a solvent reflects its molecular symmetry. The value of the relative permittivity is established from a measurement relative to vacuum. The effect is produced by the orientation of dipoles along an externally applied electric field and from the se...
