往复运动

Mud am Single and dual role of the two kinds of type, single-acting piston-type mud pump reciprocating movement in only one cycle of action to complete a suction drain.

泥浆泵分单作用及双作用两种型式﹐单作用式泥浆泵在活塞往复运动的一个循环中仅完成一次吸排水动作。

To turn a handle .the maximum movement available to a pivoted or reciprocating piece by a cam.

安装在枢轴上或作往复运动的部件，从凸轮、曲柄或偏心轮所得到或能得到的运动极限。

In addition, if the carriage reciprocates during printing operation, the coil L of the solid semiconductor element crosses inside the magnetic flux due to a plurality of permanent magnets (a movement time electromotive force supply unit) arranged on a carrier path, and so the electromotive force is generated on the coil by electromagnetic induction.

另外，如果在打印期间支架往复运动，通过被布置在运载路径上的许多永久磁铁(运动时间电动力供应单元)产生的磁通量穿入固态半导体元件的线圈L，从而通过电磁感应电动力被产生在线圈上。

An industrial sewing machine for the completion of a button hole comprises a needle holder that is connected via an arm to means which ensure a forward and backward motion perpendicular to the direction of the needle.

一种用于缝制钮扣眼（1）的工业缝纫机包括一个通过一臂（21）与一装置相连接的缝纫针夹持器（20），该装置确保缝纫针夹持器沿着垂直于缝纫针运动方向的方向往复运动。

The crank and connecting rod mechanism, the cam mechanism and the eccentric wheel mechanism are used to transform the continuous movements into the reciprocal movements, yet these mechanisms have no constant transmission ratio and there exist rather large impact force while operating at high speed.

曲柄连杆机构、凸轮机构和偏心轮机构常用来将连续运动转化为往复运动，但这些机构没有恒定的传动比，高速运转时存在较大的冲击力。

The valve core dynamic fixed flow balancing valves is compossed of pistons with changeable flow area,hi-presision(±5%)springs and sustaining devices. Affected by differential pressure and springs,the flow nipple will do piston movement.During the movement,the fliw area changes and the flow rate sustains at a constant value.

动态流量平衡阀的阀芯是由可变过流面积的阀胆和高精度（±5%）弹簧及支撑装置组成，受压差和弹簧的作用，阀胆的节流嘴可在阀胆罩内做活塞式往复运动，运动过程中流通面积发生改变，从而使流量维持在恒定值。

Since there is no moving package, there can be no normal selvages and it is usual for the projectile always to travel in the same direction when carrying the yarn rather than to reciprocate as in a normal loom.

由于纬纱卷装不运动，也就不能形成常规的布边。通常片梭携带纬纱总是沿一个方向飞行，而不是像有梭织机的梭子那样往复运动。

Slotting machine: type of machine tool in the vertical plane for reciprocating movement within, to the movement into the table to do.

4插床：该类机床刀具在垂直面内作往复运动，工作台做进给运动。

Special designed drive outfit and PLC are adopted to control object moving to-and-fro and rotating at prearranged positions.

采用特殊设计的传动机构结合PLC控制物体作直线往复运动和在预定位置作自转运动。

In the part of mechanical design, The output shaft of stepping motor connects ball screw with coupling joint, and enables worktable auto-reciprocating under the support of linear rack.

关于机械设计部分，电机输出轴经过联轴器连接滚珠丝杠带动工作台运动，工作台在直线导轨的支撑下做直线往复运动。

This paper discusses design and realizable methods of remote test output interface from logical design angle.

本文从逻辑设计的角度讨论遥测输出接口的设计及实现方法。

This also 星体投射plies to buildings, structures and geological features.

这也适用于建筑物和地质特征。
