可以知道對甲醇羰基化這一反應，在極性溶劑中，極性較大且為非質子型的溶濟能顯著提高反應的速率；非極性溶劑中，介電常數較小的溶劑能增加反應速率。 -
The eluent is changed in a regular manner starting with a nonpolar solvent and gradually replacing it by a more polar one
洗脫液以常規的順序更換，首先用非極性溶劑，然後逐步被極性較強的所替換。 -
In the packing of amphiphilic molecules, like units of the molecules interact with each other, i. e., the polar units associate with each other ; likewise, nonpolar unites associate to form hydrocarbon layers in the lamellar packing
在層狀相中雙親分子的堆積類似於分子單元間的相互作用，即極性基團與極性基團締合形成親水層，而非極性基團之間締合形成疏水層。
