electric moment

基本解释

A theory is given for the effect of the second order electric moment of crystal on dispersion by means of the Green's function method, in which account is taken of the an-harmonic potential.
本文应用格林函数方法讨论了晶体点阵的色散的二级电矩效应，并且也考虑了非简谐势的效果。
That matters for two reasons. First, various versions of the Standard Model make different predictions about the size of the electric dipole moment. Measuring it would help choose between them.
但这项工作其实很重要，原因有二：一，不同版本的标准模型给出了对偶极矩大小的不同估算，测量偶极矩值可以帮助找出正确的模型；
Second, many physicists believe the electron's electric dipole moment is a manifestation of the asymmetry that causes the universe to be made of matter.
二，许多物理学家相信：偶极矩的存在体现了宇宙的非对称性，而这种特性使我们的世界得以在物质的基础上建立。
