查询词典 anomalous magnetic moment

The QED runningcoupling constant α and the anomalous magnetic moment of muon 〓 are twofundamental quantities for the precision test of the Standard Model.

在标准模型精确检验问题中，QED精细结构常数〓和μ轻子的反常磁矩〓中强子的贡献，只能用唯象的色散理论，将夸克贡献"转化"为强子，通过〓湮灭到强子末态的实验数据的积分计算得到。

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。

Based on the function and reliability, the design principle for thepermanent magnetic bearing in rotating machine is put forward. FailureMode Effect and Criticality Analysis is studied for thepermanent magnetic bearing, and corresponding designs for magneticbearing are made to enhance the reliability. In addition, the main failuremode and failure causes are found by FMECA, it is found that theadditional alternate magnetic field within the machine causing thepermanent magnet to demagnetize is the main failure mode of thepermanent magnetic bearing in rotating machine.
