查询词典 magnetic moment

The original Slashdot article had to do with the anomalous measurements of the muon magnetic moment that cannot be derived from modern theory, and could be further evidence that the Standard Model is invalid, and that the Lorentz invariance it takes for granted cannot be perfectly accurate.

文章中的斜线和小数点符号来自不规则muon的电磁动量测量，这些结果和现代理论不符！将来可以证明经典的模型是无效的，而被人们所认可的罗伦兹不变性也不是完全准确的。

Therefore there exist the so called vacuum fluctuations. In the QED, for example, there exist the effects of zero-point oscillations of photons, the effects of vacuum polarization of electron-positron paris, and so on. They all could result in observable consequences , such as the anomalous magnetic moment of the electron, the spontaneous emission of atoms in excited states, the Lamb shift and the Casimir effect, which have been verfied in experiments.

例如，在量子电动力学中真空中存在着光子的真空零点振动效应，正负电子对的真空极化效应等等，它们都导致可观测的物理效果，如磁矩反常、激发态原子自发辐射、兰姆移动、卡西米尔效应等。
