1·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。

2·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。

3·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。

8·The results indicate that the geomagnetic dipole moment is not always kept decreasing over the past 2000 years, but increasing during nearly 400 years.

结果表明：过去2000年中，地磁场的偶极子磁矩并非一直减小，有近400年的时间是持续增长的。

9·Results shown the continued attenuation of the dipole moment in the last 50 years, and the variation of spatial spectrum of geomagnetic field continuously decreased.

研究中发现最近50年偶极矩仍在继续衰减，空间功率谱的变化也呈减小趋势。

10·So it avoids the distortion of electric cloud distribution in basis sets and can obtain a more precise computational result of the electric dipole moment of a given system.
