啤酒和洗发水都有极性分子，它们可以在气液分解面上积累，但是阻止气泡破掉的机制，对于肥皂沫和啤酒来说，有着根本上的区别。
Both beer and shampoo have polar molecules that accumulate at a liquid-gas interface, but the mechanisms that prevent bubble collapse in soap foams or pilsner heads are fundamentally different.
本文以苯乙烯和丙烯酸酯的低分子共聚物为B段，以含有极性基团的单体为A段合成了A—B嵌段型颜料分散剂。
An A-B blocked pigment-dispersing agent has been synthesised , in which the A block is a monomer with polar groups and the B fo'oek is the oligomer of styrene and acrylate with lower molecular weight.
在LLDPE的大分子上没有极性基团，它与很多基材如金属、塑料、玻璃和低的粘结力很差。
There is no polar radical on the macromolecules of LLDPE. It has poor adhesion to many substrates such as metal, plastics, glass and paper.
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".
