n.钇稀有金属元素形容词yttric简写符号Y
Noun:
a silvery metallic element that is common in rare-earth minerals; used in magnesium and aluminum alloys因发现自瑞典Ytterby镇而得名，该地字面意思为outer villageby.
1794年在瑞典小镇伊特比的黑石中发现了化学元素“钇”，决定用 Ytterby瑞典小镇伊特比命名该元素：yttrium。1842 年在该镇的黑石中发现了化学元素“铒”，决定用Ytterby 的第四、五、六、七个字母 erby 命名该元素：erbium。1842 年该镇的黑石中发现了化学元素“铽”，决定用 Ytterby 的第、四、五、六、七个字母terby 命名该元素：terbium。1907 年又在该镇的黑石中发现了化学元素“镱”，决定用 Ytterby 的全称命名该元素：ytterbium。这样，我们不但记住了这四种元素的英语名称，而且在需要时可做到脱口而出，书写无误。yttrium oxide氧化钇yttrium aluminium garnet laser钇铝石榴石激光器…yttrium fluoride氟化钇yttrium bromide溴化钇yttrium carbide碳化钇yttrium carbonate碳酸钇yttrium garnet钇石榴石yttrium nitrate硝酸钇yttrium nodular iron钇球墨铸铁yttrium chloride氯化钇yttrium phosphate磷酸钇yttrium metals钇族金属yttrium peroxide过氧化钇yttrium silicate硅酸钇yttrium iodide碘化钇yttrium hydroxide氢氧化钇
