Salts are enriched around electriferous groups of polymer molecules in solution, which formed a salt concentration gradient.(溶液中的盐份富集在聚合物分子的带电基团附近，并形成盐浓度梯度分布。)
Proton exchange membrane fuel cells use a perfluorosulfonic solid polymer film as electrolyte.(质子交换膜燃料电池采用全氟磺酸固体聚合物膜为电解质。)
They then coated the spheres with a sticky polymer before heating them again.(然后在再次加热之前给聚苯乙烯球表层涂上一层粘性聚合体。)
So we'll think about polymer configurations.(考虑聚合物的构型。)
The polymer that we use is actually the same type of polymer that's used in degradable sutures.(这里我们用的高分子实际上和用于可降解缝合线的高分子是同一种。)
Once in the polymer, the electrolyte stays there until a newly applied voltage coaxes it out.(一旦电解液被聚合物吸入，那这些液体就得待在里面，直到新输入的电压把它们给排出去。)
Yet the overall benefit depends on how long the polymer film lasts.(不过总的收益取决于这种高分子膜的耐用程度。)
As the solvent evaporated, they were left with drug mixed into a polymer film.(等到溶剂挥发后就得到混合有药物的聚合薄膜。)
And what we're envisioning is molecular or polymer configurations.(我们设想的是分子，或聚合物构型。)
The polymer was a chemical product that formed the basis for Kevlar.(这种聚合物是一种形成凯拉夫尔主要成分的化学产品。)
