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
The relative permittivity and dielectric constant are not just important when it comes to capacitors, there are also other areas as well.RF transmission lines: Within coaxial and other forms of feeder the dielectric placed between the inner and outer conductors for coaxial cable, between the...

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 value of the static dielectric constant of any material is always greater than one, its value for a vacuum. The value of the dielectric constant at room temperature (25 °C, or 77 °F) is 1.00059 forair, 2.25 forparaffin, 78.2 forwater, and about 2,000 forbarium titanate(BaTiO3)...
dielectric constant (redirected fromdielectric constants) Encyclopedia Related to dielectric constants:Dielectric materials dielectric constant n. The ratio of the permittivity of a material to that of a perfect vacuum. Also calledrelative permittivity. ...
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. ...
