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
相对介电常数/介电常数
A static permittivity is often required because the response of a material is a complex relationship related to the frequency of the applied voltage. Dielectric constant: The dielectric constant is defined as the relative permittivity for a substance or material....
Permitivity如果不加修饰词，就是指的介电常数。而Dielectric constant 是相对介电常数，也就是relative ...
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 known as the relative permittivity, is a dimensionless constant that describes how a material behaves in an electric field compared to vacuum. It reflects the material's response to an electric field and is related to its polarity. ...

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...
