lift-off speed

基本解釋

A glider wing is an efficient way to generate lift, but my seconds-long flight proved that running off a dune doesn't generate much speed.
滑翔機(jī)的機(jī)翼能有效地提供升力，但我那僅有幾秒的飛翔時(shí)間證明了，從沙丘上沖下來并不能產(chǎn)生多快的速度。
Surface proximity and swirl rotational speed are the two basic factors leading to flame lift-off asymmetry, but their influences on the flame lift-off length is not strong.
模擬的結(jié)果發(fā)現(xiàn)貼壁程度和渦流轉(zhuǎn)速是產(chǎn)生火焰浮起長度不對稱性的基礎(chǔ)，但其對火焰浮起長度的影響并不顯著；
