cerium oxide

基本解釋

• 二氧化鈰（等于ceric oxide）

英漢例句

雙語例句

• It does this because heating cerium oxide drives oxygen atoms out of its crystal lattice.
  其工作原理是，鈰氧化物加熱后可以把氧原子從其原有的晶體點陣上剝離出來。
• The prototype, which was devised by researchers in the US and Switzerland, uses a quartz window and cavity to concentrate sunlight into a cylinder lined with cerium oxide, also known as ceria.
  該機器的原型是由美國和瑞士的研究者們設(shè)計的。 它利用一個石英窗和腔體將太陽光聚集到一個充滿二氧化鈰的缸體中。
• 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》雜志里所報道的裝置使用一個標準的拋物柱面鏡把陽光搜集進一個反應(yīng)室。在這個反應(yīng)室里，鈰氧化物催化劑可以分解水和二氧化碳。
