等到溶剂挥发后就得到混合有药物的聚合薄膜。

As the solvent evaporated, they were left with drug mixed into a polymer film.

只要加入一点聚合体球体和碳颗粒就可以自然地安排成正确的晶体结构，因此生产光亮的薄膜就很容易了。

The polymer spheres and carbon particles arrange themselves spontaneously into the correct crystal structure when encouraged by a little heat, so manufacturing opalescent film should be easy.

研究者们用薄膜聚合物做成了人工翅膀，用加上塑料制的血管，使它就像是一只真正的燕尾蝶。

The researchers made artificial wings from a thin film of polymer, fabricating them with plastic veins mimicking those of an actual swallowtail butterfly.

Here is a thin membrane, it's a polymer scaffold, and on that polymer scaffold scientists have placed some skin cells and they've allowed it to grow.

这是一张薄膜,它是一个聚合物支架,在这个支架上,科学家放了一些皮肤细胞,并让它们生长
