常見例句雙語例句The cutting noise mainly root in high-frequency vibration of the circular saw blade induced by the cutting force.鋸切噪聲的主要來源是圓盤鋸在鋸切力作用下的高頻振動發(fā)聲。Though asymmetry stator mistuned may result in bigger amplitude aerodynamic force with the same frequency as rotational speed, it could reduce effectively the aerodynamic force of blade as a whole.不對稱葉柵非諧設計雖然會引起與轉速同頻的較大幅值激振力成分， 但從整體考慮可有效降低葉片振動應力。www.jasp.com.cn 返回 blade frequency force
