| 背面 |      释义： 这里所说的“阿司匹林”，是一种镇痛解热药，用来缓解疼痛和降低高烧病人的体温。“阿司匹林”是这种药物的俗称，其学名则是“乙酰水杨酸”。发明阿司匹林的是1905年的诺贝尔化学奖获得者、德国化学家拜尔（Adolf von Baeyer，1835—1917）。他通过合成的方式制造出了乙酰水杨酸（acide acétylsalicylique）。说到水杨酸，很多人都知道，绣线菊（spirée或spiraea）的主要成分便是这种酸。但是，乙酰水杨酸却并不是从这种植物中提取出来的。于是，德国人就将乙酰水杨酸这种合成酸称为“Aspirin”（并非从绣线菊中提取出来的水杨酸）。其中，“a-”是表示否定的希腊语前缀，“spir”意为“绣线菊”，“-in”是医学和化学领域常用的日耳曼语后缀。由于阿司匹林是一个统称，所以该词的首字母无须大写。音译“阿司匹林”。n. 胡桃；胡桃木adj. 胡桃科植物的 例句： 1. She watches him plane the surface of a walnut board.她看着他刨平一块胡桃木板。 walnut 胡桃来自古英语walhnutu,外国坚果，walh-,外国的，外来的，词源同Welsh,Cornwall,nut,坚果。以此命名，以与本国坚果相区别。 walnutwalnut: [OE] A walnut is etymologically a ‘foreign nut’. Its name alludes to the fact that the nut was regarded by the Germanic peoples as an exotic import from southern Europe, land of Romans and Celts (their own native nut was the hazel). Prehistoric Germanic *walkhaz originally meant ‘Celtic’ (it was borrowed from Latin Volcae, the name of a Celtic people), but it soon broadened out to include anyone or anything foreign (including the Romans) within its scope.Its original Celtic connotations survive, however, in Welsh and Walloon (the name of a people of Gaulish origin), both of which go back to *walkhaz. English shares the formation walnut with its Germanic neighbours – German walnuss, Dutch walnoot, Swedish valnöt, and Danish valnød.=> walloon, welshwalnut (n.)Old English walhnutu "nut of the walnut tree," literally "foreign nut," from wealh "foreign" (see Welsh) + hnutu (see nut). Compare Old Norse valhnot, Middle Low German walnut, Middle Dutch walnote, Dutch walnoot, German Walnuss, So called because it was introduced from Gaul and Italy, distinguishing it from the native hazel nut. Compare the Late Latin name for it, nux Gallica, literally "Gaulish nut." Applied to the tree itself from 1600 (earlier walnut tree, c. 1400)." |
