n.圆柱

PP, PVC, PET cyclinder leather waste or rubber should be cutted to small piece. 如PP、PVC、PET圆柱皮件回收料或橡胶粉碎前之切块用。

Its appearance is good with a cyclinder steel base, and is small in size and light weight. 圆筒形钢板机座，外观精致。整体体积小、重量轻、造型新颖。

This paper analysed the main reasons that influence theperformance of cyclinder head,valve and valve seat in internal combustion engine. 同轴度是影响内燃机气缸盖、气门与座圈工作性能的关键技术要求。

Cavitation erosion is related to bubbles.Bubbles pop out from drilling fluid in vacuum conditiun and form air mass against cyclinder well. 气蚀发生的条件与气泡密切相关，气泡在真空时从钻井液中溢出形成气团，并紧靠缸壁；

A new control method of hydraulic cylinder speed is put forward.It control the cyclinder speed by discrete precise displcement. 提出了一种新的控制液压缸执行速度的方法，将柱塞的速度控制通过离散的精确位移来实现。
