往复

An eccentric or multiply curved wheel mounted on a rotating shaft, used to produce variable or reciprocating motion in another engaged or contacted part.

凸轮安装于旋转轴上的偏心轮或复合曲线轮，用以使相连的或相接触的其它部件产生多变的或往复的运动

This thesis aimed to discuss an electromagnetic energy harvester. Motion of a fluid driven by a 30 Hz pulse pump is used to activate the electromagnetic energy harvester. The periodic motion of the fluid in the chamber causes a harmonic vertical deflection in the diaphragm on which a permanent magnet is attached. Subsequently, the vibration of this magnet induces an output voltage in a solenoid hanging above it.

中文摘要本文是探讨电磁式能量产生器的机构，此电磁式能量产生器的主要作动方式为藉由频率30Hz的脉冲马达驱动工作流体，使工作流体呈周期性的流动让帮浦腔体上致动薄膜产生周期性的上下往复运动，因此帮浦腔体内产生压力周期性的变化，在薄膜上永久磁铁的振动，使得螺旋线圈感应产生电压的输出。

But a volleyer will jump back into other commitments and relationships during downtimes.

The AJQ series Blowing and Sucking Traveling Cleaner is compatible with every type of spinning frame,fly frame,loom machine,twister,winder,double-wire machine and warper manufactured home and abroad.

AJQ系列巡回吹吸清洁机可与国内外各种型号的细纱机、粗纱机、织布机、倍捻机、络筒机、并纱机、整经机等主机配套使用。其主要功能是对纺织机各部位进行往复巡回清洁。

With the improvement of the structural complication and strength index of the engine structure, during the work process, the bending-shaft produce bent and torsion because of the action of periodicity variational air pressure, inertia pressure evocabled by the to-and-fro and whirligig motion and torque, therefore, engine bending-shaft must be provided with the preferable fatigue intensity and the structure rigidity through making use of the material of high intensity and the reasonable forging technique.

随着发动机结构的复杂化和强化指标的不断提高，曲轴在工作过程中，由于受到周期性变化的气压力、往复和旋转运动引起的惯性力以及弯矩、扭矩的共同作用，既产生弯曲又出现扭转，这就要求发动机曲轴具有高的疲劳强度和结构刚度。

LTHJ-SUPER-A1 Gantry welding automatic recovery machine This system is set for one body super new portal welder, special cylindrical welding tools or difficult welding. It adds super negative pressure wind pump on inner side of flux cylinder, so that in the welding process it can absorb unlyzed flux directly into cylinder and place into a small hopper. Open the valve of small hopper and put flux onto work piece, then you can put it into repeated usage.

LTHJ-SUPER-A1型龙门焊自动回收系统本系统是一体超强新型的门式焊机或外圆焊接特制工具、高难度的焊接而设置的，它就是一个焊剂筒内加上超强负压风泵，使在焊接过程中尚未溶化的焊剂直接吸收到筒内，放置到小料斗中，打开小料斗阀门把焊剂放到工件上，进行往复使用。

In planing, the workpiece is attached to a worktable that reciprocate s past the cutting tool.

在牛头刨削操作中，工件被固定在一个沿着刀具作往复运动的工作台上。

Such-and-such, it start shoot forth in the end of march of the eighth years, florescence is from april to may, in the end of april it begins abloom, anthesis is mainly the middle ten days of may. at the same time, it is full of white lactic resin in the stem, collect the resin and put its at ventilated, shady and cool place.

如此往复，到第8年3月底开始见旬抽茎，花期4月底5月底，4 月底始花，5月中旬为盛花期，此时里面充满白色乳液状树脂，收集树脂，将收集的树脂在通风阴凉处阴干，即得块状凝固的树脂，入药称阿魏。

An experiment facility is set up, which consisted of a ceramic foam combustor, a gas flow system controlled by two pairs of solenoid valves for switching alternatingly the flow directions, and a measurement system.

预混合气体在多孔介质内往复流动下的超绝热燃烧是一项先进的燃烧技术，它以其高效、低污染的优越性正在引起人们的关注。

Reciprocating means up and down or banck and forth, It is the up and down action of a piston in the cylinder blick, or engine block.

大多数汽车的发动机是内燃机，往复四冲程汽油机，但是也有使用其它类型的发动机，包括柴油机，转子发动机，二冲程发动机和分程燃烧发动机。

But we don't care about Battlegrounds.
