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 (also calledrelative permittivity) is a dimensionless number that indicates how much a material increases the capacitance of a capacitor compared to a vacuum. Vacuum has a dielectric constant of 1, which means it does not affect the capacitance at all. Air has a dielectric...
Mathematically, dielectric constant is the ratio of a material'spermittivityto thepermittivity of free space. This is why it is also known asrelative permittivity. It is the electrical equivalent of relativemagnetic permeability. More about dielectric constant ...
