词汇 prussian
词源
Prussian; Prussian blue; prussiate; prussic acid. Since the Franco-Prussian War of 1870, when Prussia’s militarism came into full flower, Prussian has been a synonym for arrogant, overbearing, cruel, and excessively military. Prussian blue, however, has nothing to do with the military, merely having been discovered by the Prussian chemist Diesbach in 1704. It is a color ranging from moderate to deep greenish blue used in painting and fabric printing. A prussiate is a ferricyanide or ferrocyanide, which the color was made from, while prussic acid (hydrocyanic acid) is made from Prussian blue. Prussian blue is sometimes called Berlin blue, after its place of discovery.
