n. [化学] 钨（金属元素，符号 W）；钨锰铁矿

n. (Wolfram)人名；(英、匈、芬、德、瑞典)沃尔弗拉姆

wolfram (n.): 1757, from German Wolfram, wolform "iron tungstate" (1562), of obscure etymology. It looks like "wolf-cream" (from rahm "cream"), but the second element might be Middle High German ram (German Rahm) "dirty mark, soot;" if so, perhaps "so called in sign of contempt because it was regarded of lesser value than tin and caused a considerable loss of tin during the smelting process in the furnace" [Klein]. Or perhaps the word is originally a personal name, "wolf-raven."
