n.圓柱

PP, PVC, PET cyclinder leather waste or rubber should be cutted to small piece. 如PP、PVC、PET圓柱皮件回收料或橡膠粉碎前之切塊用。

Its appearance is good with a cyclinder steel base, and is small in size and light weight. 圓筒形鋼板機(jī)座，外觀精致。整體體積小、重量輕、造型新穎。

This paper analysed the main reasons that influence theperformance of cyclinder head,valve and valve seat in internal combustion engine. 同軸度是影響內(nèi)燃機(jī)氣缸蓋、氣門與座圈工作性能的關(guān)鍵技術(shù)要求。

Cavitation erosion is related to bubbles.Bubbles pop out from drilling fluid in vacuum conditiun and form air mass against cyclinder well. 氣蝕發(fā)生的條件與氣泡密切相關(guān)，氣泡在真空時(shí)從鉆井液中溢出形成氣團(tuán)，并緊靠缸壁；

A new control method of hydraulic cylinder speed is put forward.It control the cyclinder speed by discrete precise displcement. 提出了一種新的控制液壓缸執(zhí)行速度的方法，將柱塞的速度控制通過離散的精確位移來實(shí)現(xiàn)。
