這些起重機(jī)，液壓沖力并不是作用于吊桿上，而是作用于一個鉸鏈連接桿。
We felt like we had good pace but the head stay hydraulic ram lost some pressure, which affected the positioning of the mast, and sail trim.
起航階段我們可以感覺到速度很快,但不久液壓系統(tǒng)就出現(xiàn)問題,影響了我們對桅桿的控制和對帆的調(diào)整。
RICHARD YEM SYNC: Under the action of the waves the hydraulic ram's blue unit, shown down here on my left, pumps high pressure fluid into these large accumulators.
RICHARD同步解說:在波的作用下，液壓油缸的藍(lán)色單元，在我的左邊，將高壓液體泵入大型蓄電池。
In doing so, each of these long sections articulates up and down and side to side, and the movement’s resisted by hydraulic rams which convert that mechanical energy into electricity.
這種運(yùn)動反作用于液壓裝置，由此把機(jī)械能轉(zhuǎn)換為電能。
