翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Charge invariance ： ウィキペディア英語版 Charge invariance (詳細はpotential of a particle, regardless of speed. For example, an electron has a specific rest charge. Accelerate that electron, and the charge remains the same (as opposed to the relativistic mass and energy increasing). The key word here is relativistic. Some particle characteristics are relativistically invariant (charge, spin, and magnetic moment). Others are relativistic (mass, energy, and de Broglie wavelength). The key is the Lorentz factor, $\backslash gamma\; =\; \backslash frac)^2\}\}$ where $v$ is speed, and $c$ is the speed of light. Typically, we write: $E\; =\; \backslash gamma\; E\_0\; \backslash ,\backslash !$ $m\; =\; \backslash gamma\; m\_0\; \backslash ,\backslash !$ $e\; =\; e\_0\backslash ,\backslash !$ $\backslash frac\; =\; \backslash frac\backslash ,\backslash !$ where the first equation describes relativistic energy, the second – relativistic mass, the third – charge invariance, and fourth – spin invariance. Notice that $\backslash gamma$ does not appear in the third or fourth equations. $\backslash gamma$ is a function of speed (relative to some rest frame where $E\_0$ and $m\_0$ refer to rest energy and mass). So, to say "rest charge" or "rest spin" is redundant. Notice also that as $v$ (speed) increases, $\backslash gamma$ increases, and so $E$ (and $m$) increases too. The origin of charge invariance (indeed, all relativistic invariants) is under speculation presently. There may be some hints proposed by string/M-theory. It is possible the concept of charge invariance may provide a key to unlocking the mystery of unification in physics (the theoretical unification of gravity, electromagnetism, the strong, and weak nuclear forces). The property of charge invariance follows from the vanishing divergence of the charge-current four-vector $j^\backslash mu=(c\backslash rho,)$, with $\backslash partial\_\backslash mu\; j^\backslash mu=0$. 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「Charge invariance」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.
