翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク nullcline ： ウィキペディア英語版 nullcline In mathematical analysis, nullclines, sometimes called zero-growth isoclines, are encountered in a system of ordinary differential equations :$x\_1\text{'}=f\_1(x\_1,\; \backslash ldots,\; x\_n)$ :$x\_2\text{'}=f\_2(x\_1,\; \backslash ldots,\; x\_n)$ ::$\backslash vdots$ :$x\_n\text{'}=f\_n(x\_1,\; \backslash ldots,\; x\_n)$ where $x\text{'}$ here represents a derivative of $x$ with respect to another parameter, such as time $t$. The $j$'th nullcline is the geometric shape for which $x\_j\text{'}=0$. The fixed points of the system are located where all of the nullclines intersect. In a two-dimensional linear system, the nullclines can be represented by two lines on a two-dimensional plot; in a general two-dimensional system they are arbitrary curves. == History == The definition, though with the name ’directivity curve’, was used in a 1967 article by Endre Simonyi1. This article also defined 'directivity vector' as $\backslash mathbf\; =\; \backslash mathrm(P)\backslash mathbf\; +\; \backslash mathrm(Q)\backslash mathbf$, where P and Q are the dx/dt and dy/dt differential equations, and i and j are the x and y direction unit vectors. Simonyi developed a new stability test method from these new definitions, and with it he studied differential equations. This method, beyond the usual stability examinations, provided semiquantative results. 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「nullcline」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.
