英语词源
anodeanode: [19] The term anode, meaning ‘positive electrode’, appears to have been introduced by the English philosopher William Whewell around 1834. It was based on Greek ánodos ‘way up’, a compound noun formed from aná- ‘up’ and hodós ‘way’ (also represented in exodus ‘way out’ and odometer ‘instrument for measuring distance travelled’, and possibly related to Latin cēdere, source of English cede and a host of derived words). It specifically contrasts with cathode, which means literally ‘way down’.=> exodus, odometeranode (n.)1834, coined from Greek anodos "way up," from ana "up" (see ana-) + hodos "way" (see cede). Proposed by the Rev. William Whewell (1794-1866), English polymath, and published by English chemist and physicist Michael Faraday (1791-1867). So called from the path the electrical current was thought to take. Related: Anodic.
