n.水力學(xué)；液壓裝置

A more well known branch of fluid power is hydraulics. 流體動(dòng)力的一個(gè)更廣為人知的分支是水力學(xué)。

The seepage of irregular fracture is a very important problem in rock hydraulics. 不規(guī)則裂隙的滲流問(wèn)題是巖體水力學(xué)中一個(gè)比較復(fù)雜的問(wèn)題。

In automatics, hydraulics or servomotors do the work. 自動(dòng)變速箱中則是由液壓裝置或伺服馬達(dá)做這個(gè)動(dòng)作。

Several of our research discoveries have been adapted for commercial use, and one particular breakthrough in linear hydraulics is now being used by every oil company in the country. 我們的幾項(xiàng)研究發(fā)明經(jīng)轉(zhuǎn)化已被應(yīng)用于商業(yè)領(lǐng)域，特別是在線性液壓方面的一項(xiàng)突破性成果現(xiàn)在被國(guó)內(nèi)各家石油公司采用。
