dipole moment

常见例句

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。
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；
Measuring the electric dipole moment, then, is the sort of thing that really floats physicists' boats.
所以測量偶極矩對物理學界來說確實是顛覆性的工作。

The dipole moment of an object is a measure of how electrical charge is distributed within it.

The dipole moment of a hexamer of water molecules turns out to be almost identical to the dipole moment of bulk quantities of water—indicating that liquid water is made up of cage-shaped hexamers.
