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，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。
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；
Measuring the electric dipole moment, then, is the sort of thing that really floats physicists' boats.
所以测量偶极矩对物理学界来说确实是颠覆性的工作。

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.
