This length scale arises naturally in discussions of electrostatic, electrodynamic and electrokinetic phenomena in electrolytes, polyelectrolytes and colloidal dispersions. In standard units, the Bjerrum length is given by $\backslash lambda\_B\; =\; \backslash frac,$ where $e$ is the elementary charge, $\backslash varepsilon\_r$ is the relative dielectric constant of the medium and $\backslash varepsilon\_0$ is the vacuum permittivity. For water at room temperature ($T\; =\; 300\; \backslash mbox$), $\backslash varepsilon\_r\; \backslash approx\; 80$, so that $\backslash lambda\_B\; \backslash approx\; 0.7\; \backslash mbox$. In Gaussian units, $4\backslash pi\backslash varepsilon\_0\; =\; 1$ and the Bjerrum length has the simpler form $\backslash lambda\_B\; =\; \backslash frac.$ ==References== 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「Bjerrum length」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.
