翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Screened Poisson equation ： ウィキペディア英語版 Screened Poisson equation In physics, the screened Poisson equation is a partial differential equation, which arises in (for example) Klein–Gordon equation and electric field screening in plasmas. ==Statement of the equation== The equation is :$$ \left(\Delta - \lambda^2 \right ) u(\mathbf) = - f(\mathbf), where $\backslash Delta$ is the Laplace operator, ''λ'' is a constant, ''f'' is an arbitrary function of position (known as the "source function") and ''u'' is the function to be determined. In the homogeneous case (f=0), the screened Poisson equation is the same as the time-independent Klein–Gordon equation. In the inhomogeneous case, the screened Poisson equation is very similar to the inhomogeneous Helmholtz equation, the only difference being the sign within the brackets. 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「Screened Poisson equation」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.
