常見(jiàn)例句雙語(yǔ)例句The amount of blade twist is called the pitch angle .葉片扭曲的量被稱(chēng)之螺鏇上陞角。Blade twist is important because a propeller moves at much greater speed at the blade tips than at the center hub.槳葉扭轉(zhuǎn)非常重要，因爲(wèi)槳葉葉梢的鏇轉(zhuǎn)速度遠(yuǎn)高於槳葉的中心。The maximum load is at the axis of blade twist and the tip portion. The blade load is the minimum when the hub/tip ratio is 0.45.葉片扭曲軸線処和葉頂部分承受了最大載荷，輪轂比0.45時(shí)葉片負(fù)荷最?。?/li> 返回 blade twist
