分子最稳定的定向是在沿表面的分子吸引力最大处。

The most stable orientation of the molecular attraction lie along the surface.

“氢键”这个名字使用不当，因为它不是真正的键，而是特别强的极性分子间的吸引力。

The name "hydrogen bond" is something of a misnomer, as it is not a true bond but a particularly strong dipole-dipole attraction.

粗糙的有纹路的曼妥斯促使泡泡增长，因为他们有效地中断水分子之间的极吸引力，使泡泡数量变多了。

The rough, dimply surfaces of Mentos encourage bubble growth because they efficiently disrupt the polar attractions between water molecules, creating bubble growth sites.

There are no other molecules on that side of the wall. So there's an attractive force that makes the velocity within not quite as fast.

墙的另一边没有分子,因此吸引力,会降低球的速度。

And then V minus the excluded volume term is equal to RT. Two parameters, this is the attraction between two atoms or molecules in the gas phase.

以及V减去一个排斥项,等于RT，两个参数，这是气体状态下两个原子,或者分子之间的吸引力。
