1·When electricity, whether from photovoltaic cell, wind turbine or other sources, runs through the electrode, the cobalt and phosphate form a thin film on the electrode and oxygen gas is produced.
当电流——无论是来自光伏电池、风轮机还是其它来源——穿过电极时，钴和磷酸盐会在电极上形成一层薄膜，氧气就生成了。
2·The thin film allows batteries to charge and recharge quickly, but at the cost of significant degrading over time.
这个薄膜为了让电池能够更快地充电，但是这以其最终会明显退化为代价。
3·Conventional lithium-ion or nickel metal hydride rechargeable batteries contain active material that is placed into a thin film.
传统的锂离子以及金属氢化物镍蓄电池中所含有的活性物质被放置在一个薄膜中。
4·The researchers made artificial wings from a thin film of polymer, fabricating them with plastic veins mimicking those of an actual swallowtail butterfly.
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。
5·It looked like a clear thin film over your eyes.
它看起来就像一层覆盖在你眼睛上的透明薄膜。
