cerium dioxide

基本解释

When water vapor was used, the catalyst would strip out its oxygen to reform cerium dioxide.
如果用於分解的物質是水蒸汽，那麽二氧化鈰催化劑還可以將分解出的氧氣用於二氧化鈰的再生。
Cerium dioxide has high refractive index and dielectric constant and ultraviolet absorption which may be useful for various optical and electronic applications.
二氧化鈰具有高折射率、介電常數和紫外吸收率，因此它廣泛地應用於各種光學和電子器件。
The device, reported in the journal Science, uses a standard parabolic mirror to focus the sun's rays into a reaction chamber where the cerium oxide catalyst breaks down water and carbon dioxide.
這種在《科學》襍志裡所報道的裝置使用一個標準的拋物柱麪鏡把陽光搜集進一個反應室。在這個反應室裡，鈰氧化物催化劑可以分解水和二氧化碳。
