Dielectric constant | Definition, Formula, Units, & Facts | Britannica
dielectric constant, property of an electrical insulating material (a dielectric) equal to the ratio of the capacitance of a capacitor filled with the given material to the capacitance of an identical capacitor in a vacuum without the dielectric material.
relative permittivity相对电容率或者specific inductive capacity，它是一个电绝缘（电介质）材料的重要属性。一般来说， 介电常数的大小是填充了该电介质材料的平板电容器capacitor 的电容值 capacitance 和真空下无电介质的相同面积的理想的平板电容器的电容值之间的
用ZAHNER电化学工作站如何得到介电常数和介质损耗的数据？
相对介电常数，也叫relative permittivity相对电容率或者specific inductive capacity，它是一个电绝缘（电介质）材料的重要属性。 一般来说，介电常数的大小是填充了该电介质材料的平板电容器capacitor的电容值capacitance和真空下无电介质的相同面积的理想的平板电容器的电容值之间的比值，符号是小写的希腊字母kappa，公式是κ=c/c0或εr=ε/ε0，真空的介电常数是1。 凡本网注明“来源：化工仪器网”的所有作品，均为浙江兴旺宝明通网络有限公司-化工仪器网合法拥有版权或 …
CHAP. IV - Specific Inductive Capacity - Cambridge University …
2010年9月7日 · Specific Inductive Capacity. Faraday found that the charge in a condenser between whose surfaces a constant difference of potential was maintained depended upon the nature of the dielectric between the surfaces, the charge being greater when the interval between the surfaces was filled with glass or sulphur than when it was filled with air.
In words, the specific inductive capacity as determined by charge or discharge of a condenser at any given potential and distance between the plates is the arithmetic mean of the inductive capacity deter-mined by the force resisting separation of the plates and of that deter-mined by lateral pressure, the potential and distance being the same.
On the Measurement of Specific 'Inductive Capacity. 139 1. y-rays are produced by the /8-rays of radium ES in different materials, the greater in amount the greater the atomic weight of the material. 2. The y-rays of radium E may be entirely secondary in nature. At all events, the y-radiation can be greatly increased by a suitable disposition of
On the specific inductive capacities of certain electric substances
The author, pursuing the experimental inquiry suggested by the theory of Mr. Faraday relative to the differences in specific inductive capacity exhibited by different dialectric substances, instituted a series of experiments for determining with precision their comparative powers of insulation, and of sustaining by induction charges of electricity.

2015年1月1日 · The specific inductive capacity relative to the ether (practically to the air) of a dielectric is the ratio \\(\\frac{1\\,+\\,4\\pi \\varepsilon F}{1\\,+\\,4\\pi \\varepsilon F_0}\\); for all dielectrics known, it has a finite value; it varies between \\(1\\) (ether) and \\(64\\) (distilled water).
Dictionary:Dielectric constant (ε) - SEG Wiki
It is the dimensionless ratio of the capacitivity or permittivity, the ratio of the electrical displacement D to the electric field strength E, of the material to that of free space: Also called specific inductive capacity. It is frequency and temperature dependent.
