These tiny semiconductors inject electrons into a metal oxide film or "sensitize" it to increase solar energy conversion.

这些微小的半导体把电子注入到金属氧化物薄膜中，或者说把它“敏化”，从而增强太阳能转换。

The assumption is made that if there is no detectable free iron, the metal surface is clean enough for a uniform oxide film to develop.

假定如果没有探测到游离铁，则金属表面就是足够清洁以形成均一的氧化物膜的。

Data and programs are stored as electromagnetic charges on a metal oxide film coating the mylar plastic.

程序和数据是以电磁荷的形式存储在聚脂塑料外面包着的金属氧化胶片上。
