查询词典 moment

We have no announcements to change it at the moment though.

我们目前没有做出改变的意向。

It turns out, that the anomalous magnetic moment of the nucleon has negligible influence upon the

结果指出：核子的反常磁矩对于磁多极内转换系数以及由于质子跃迁导致的电多极内转换系数的影响微不足道。

The retarded interaction between the charged particles with anomalous magnetic moment is derived by the correspondence method.

然后用对应的方法推导出具有反常磁矩的荷电粒子之间的推迟相互作用。

But this treatment introduces two new parameters ku and kd, and the values of the anomalous magnetic moment need further studying.

当把夸克看成有结构的，即夸克存在不恒为一的结构函数，并且反常磁矩不再为零，这样便引入了两个新参数一夸克的反常磁矩，在正常合理的参数下计算结果与实验的符合表明有所改进，不过参数的合适选择看来仍起关键作用。

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。

Instead they have an improved idea which is to apply a suitable magnetic field and exploit the anomalous magnetic moment of the Lambda baryons to measure simultaneously their polarization along three independent axes turning a passive measurement -one involving a check of the decay kinematics of the Lambda particles- into an active one -directly figuring out the polarization.

相反， 他们有一个更好的想法，这是一个合适的申请，并利用磁场异常磁矩的兰布达同时重子来衡量其偏振沿着三个独立的斧头，把被动测量一个涉及检查的衰变运动学粒子的兰布达，成为一个活跃的一个直接计算出的两极分化。

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。
