Infra - red absorption takes place only when there is a change of dipole moment.

红外吸收峰仅在有偶极矩变化时才能实现。

Any heteronuclear diatomic molecule must have a dipole moment since its two ends are different.

任何异核双原子分子必然具有偶极矩，因为它的两端是不同的。

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。

Phenomenological and theoretical interpretation of the dipole moment was discussed in this paper.

对偶极矩作了象观和理论上的描述。

The dipole moment of a permanent magnet for Alpha Magnetic Spectrometer (AMS) is discussed in the paper.

本文主要研究阿尔法磁谱仪(简称ams)永磁磁体的磁矩问题。
