cerium oxide

基本解釋

• 二氧化鈰（等于ceric oxide）

英漢例句

雙語(yǔ)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(diǎn)陣上剝離出來(lái)。
• 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(jī)器的原型是由美國(guó)和瑞士的研究者們?cè)O(shè)計(jì)的。 它利用一個(gè)石英窗和腔體將太陽(yáng)光聚集到一個(gè)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(xué)》雜志里所報(bào)道的裝置使用一個(gè)標(biāo)準(zhǔn)的拋物柱面鏡把陽(yáng)光搜集進(jìn)一個(gè)反應(yīng)室。在這個(gè)反應(yīng)室里，鈰氧化物催化劑可以分解水和二氧化碳。
