electric moment

基本解釋

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.

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.
但這項工作其實很重要，原因有二：一，不同版本的標準模型給出了對偶極矩大小的不同估算，測量偶極矩值可以幫助找出正確的模型；
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，許多物理學家相信：偶極矩的存在躰現(xiàn)了宇宙的非對稱性，而這種特性使我們的世界得以在物質的基礎上建立。
