本文通过选用十一种具有极性梯度的不同固定液，探讨桂皮酸顺反异构体硅烷醚衍生物分离与选择性分子间引力的关系，并从分子结构的角度来阐述选择相应固定液进行异构体分离的可能性。
It is proposed that selective intermolecular force can be used as a new parameter for; selecting stationary phase in order to separate the isomer but not the "polarity similarity principle".
“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.
在巨分子云聚合形成过程中，一般都包括了分子云间的非弹性碰撞与分子云间的自引力。
The inelastic collision between clouds and the self -gravitation among clouds are included in the aggregation formation of GMCs.
分子间唯一的力是次价键的引力。
The only forces between molecules are secondary bond forced of attraction.
如果亚原子粒子间的吸引力再弱一点，氢原子就会悬浮不定，也就没有了原子分子，生命也不存在了。
If the forces that bind together subatomic particles were just a little weaker, there would be a lot of hydrogen floating around, but no atoms, no molecules, and again, no life.
分子间的距离较大时，如在气体中，分子间的作用力极为微小，而且是引力。
When the separation of the molecules is large, as in a gas, the force is extremely small and attractive.
分子间的距离较大时，如在气体中，分子间的作用力极为微小，而且是引力。
When the separation of the molecules is large, as in a gas, the force is extremely small and attractive.
