The semi-diameters of a non-circular ellipse are the halves of its extents along the two axes of symmetry. They are the parameters ''a'', ''b'' of the implicit equation :$\backslash left(\backslash frac\backslash right)^+\backslash left(\backslash frac\backslash right)^=1;\backslash ,\backslash !$ Likewise, the semi-diameters of an ellipsoid are the parameters ''a'', ''b'', and ''c'' of its implicit equation :$\backslash left(\backslash frac\backslash right)^+\backslash left(\backslash frac\backslash right)^+\backslash left(\backslash frac\backslash right)^=1;\backslash ,\backslash !$ The semi-diameters of a superellipse, superellipsoid, or superquadric can be identified in the same way. 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「Semidiameter」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.
