3.As both insulator and energy storage media, de-ionized water combines the advantages of high relative permittivity(is about 80), self repairability, low cost and ease of handling.水介质具有高的相对介电常数(约80),而且具有自我恢复的能力,在脉冲功率系统中被广泛应用。 3)dielectric constant相对介...
Dielectric properties of a material are a measure of the potential for charge movement inside the material in response to anexternal electric field. Dielectric properties predict how nonmagnetic materials such as foods interact with electromagnetic radiation. Thedielectric constant(permittivity,ε′) indicat...
The dc electric-field dependence of the relative dielectric constant (E) in polar dielectrics is studied. The Landau-Ginzburg-Devonshire (LGD) theory and its approximate treatments in dealing with (E) are reviewed. It is found that the LGD theory works well in the case of a single polarizatio...

Thus, a set of formulas is proposed to fit the temperature dependence of the dielectric constant at different frequencies. The formulas are strictly certified with the measured data of both materials. The formulas can fit the measured relation with high precision. The fitted results confirm and/or...
