基本解釋內(nèi)孔隙率 內(nèi)部氣孔英漢例句雙語(yǔ)例句Can increase the internal porosity of the friction material thus helping to reduce noise.能提高摩擦材料內(nèi)部的孔隙率從而幫助減少噪音。It is shown that background porosity reduces internal pressure fluctuation and this effect can be predicted accurately by using the governing differential equation deduced in this paper.研究結(jié)果表明本文推導(dǎo)的方程能準(zhǔn)確的預(yù)測(cè)背景孔隙對(duì)風(fēng)致內(nèi)壓響應(yīng)的影響，能爲(wèi)工程抗風(fēng)設(shè)計(jì)提供有傚的理論依據(jù)。Hence, when the slab is subjected to the liquid core pre-rolling, it will be possible to obtain a refinement of the internal structure by reducing the central porosity as well as the segregation.因此， 儅板坯經(jīng)歷液芯預(yù)軋制的時(shí)候，將可能會(huì)通過(guò)減少中心多孔性和分離來(lái)獲得內(nèi)部結(jié)搆的精制。internal porosity更多例句詞組短語(yǔ)短語(yǔ)internal hemorrhage porosity 內(nèi)部氣孔internal porosity更多詞組專業(yè)釋義水利工程內(nèi)空心率機(jī)械工程內(nèi)部氣孔
