单词 paddle wheel
释义

paddle wheeln.

Brit. /ˈpadl wiːl/, U.S. /ˈpædl ˌ(h)wil/
Origin: Formed within English, by compounding. Etymons: paddle n.1, wheel n.
Etymology: < paddle n.1 + wheel n.
1. A large (typically steam-driven) wheel with paddles or boards fitted around its circumference, situated at the stern or on each side of a ship, and propelling it by rotation about a horizontal axis that pushes the lower paddle-boards backward through the water. Cf. paddle n.1 3.In quot. 1685, conceived of as a wheel with paddle-like spokes or oars, rather than boards. Theorists and inventors during the 18th cent. seem to have avoided the term, writing mainly of the ‘wheel’, ‘waterwheel’, ‘rowing-wheel’, ‘revolving oars’, etc.; when boards were introduced, the term was further felt to be inappropriate, but came in gradually after 1815.
