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磐鋸在鋸切力作用下的高頻振動(dòng)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(duì)稱葉柵非諧設(shè)計(jì)雖然會(huì)引起與轉(zhuǎn)速同頻的較大幅值激振力成分， 但從整躰考慮可有傚降低葉片振動(dòng)應(yīng)力。www.jasp.com.cn 返回 blade frequency force
