| 词汇 | tungsten |
| 词根词缀 | 词源： rare metallic element, 1796, from Swed. tungsten "calcium tungstate," coined by its discoverer, Swed. chemist Karl Wilhelm Scheele (1742-86) from tung "heavy" + sten "stone." Used earlier as the name for calcium tungstate (1770). Atomic symbol W is from L. wolframium, from Ger. Wolfram "iron tungstate," of obscure etymology; it looks like "wolf-cream" (from rahm "cream"), but the second element might be from M.H.G. ram "dirty mark, soot." |
