单词 air cell
释义

air celln.

Brit. /ˈɛː sɛl/, U.S. /ˈɛr ˌsɛl/
Origin: Formed within English, by compounding. Etymons: air n.1, cell n.1
Etymology: < air n.1 + cell n.1 In sense 1a perhaps after French cellule aérienne (1772 or earlier in this sense, apparently originally in ornithological use). In sense 1b perhaps after German Luftzelle (1815 or earlier in this sense; 1802 or earlier in anatomical, 1811 or earlier in zoological use) or French cellule d'air (1815 or earlier in this sense). Compare German Luftbehälter (1802 or earlier in zoological use, 1810 or earlier in botanical use), lit. ‘air container’ (compare quot. 1832 at sense 1b).
