翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Electric susceptibility ： ウィキペディア英語版 Electric susceptibility In electricity electromagnetism, the electric susceptibility $\backslash chi\_\{\backslash text\{e\}\}$ (latin: ''susceptibilis'' “receptive”) is a dimensionless proportionality constant that indicates the degree of polarization of a dielectric material in response to an applied electric field. The greater the electric susceptibility, the greater the ability of a material to polarize in response to the field, and thereby reduce the total electric field inside the material (and store energy). It is in this way that the electric susceptibility influences the electric permittivity of the material and thus influences many other phenomena in that medium, from the capacitance of capacitors to the speed of light.〔 〕〔 〕 ==Definition of volume susceptibility== Electric susceptibility is defined as the constant of proportionality (which may be a ) relating an electric field E to the induced polarization density P such that: :$=\backslash varepsilon\_0\backslash chi\_,$ where * $\backslash mathbf$ is the polarization density; * $\backslash varepsilon\_0$ is the Vacuum permittivityo the induced dielectric polarization density P such that: :$=\backslash varepsilon\_0\backslash chi\_,$ where * $\backslash mathbf$ is the polarization density; * $\backslash varepsilon\_0$ is the electric permittivity of free space; * $\backslash chi\_$ is the electric field. The susceptibility is also related to the polarizability of individual particles in the medium by the Clausius-Mossotti relation. The susceptibility is related to its relative permittivity $\backslash varepsilon\_\}\backslash \; =\; \backslash varepsilon\_\}\backslash \; =\; 0$ At the same time, the electric displacement D is related to the polarization density P by: :$\backslash mathbf\; \backslash \; =\; \backslash \; \backslash varepsilon\_0\backslash mathbf\; +\; \backslash mathbf\; \backslash \; =\; \backslash \; \backslash varepsilon\_0\; (1+\backslash chi\_\; \backslash \; =\; \backslash \; \backslash varepsilon\_.$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Electric susceptibility」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
