往复

The valveless pump has inlet and outlet with tapered tube and does not need control of valves. The flow rectification of the valveless pump can be realized based on the nozzle/diffuser action. The differential SMA actuator controlled by alternative current makes the baffle of the valveless pump reciprocating motion.

该无阀泵具有锥形入口和出口而不需要阀门控制，单方向泵流是靠锥形入口和出口的收缩和膨胀作用实现的，差动式形状记忆合金执行器在交变电流的控制下使无阀泵的挡板往复运动。

The flexible shafts have better strength and rigidity than ordinary level, they are ideal substitute for conventiona level and universaljoint with such merits as : light weight, good flexibility, easily crooking, compact constru—ction, easily installation, good seal, proof rust and anti—deformation, neatly operation.

工作原理：机械操纵系统中的连接部位受力位移时，软轴的芯轴受力，产生往复运动，形成拉力、推力驱使机械作换挡、取力、升降、行走、加油、熄火、制动、转向、换向等工作，它不但优于一般杠杆的强度、刚性而且重量轻、柔性好、可弯曲、结构紧凑、安装方便、密封性好，不易锈蚀变形，操作轻便灵活，是替代传统的连杆、万向节机构的理想产品。

To start immediately to implement this plan, made large quantities of high performances the absolutely counter-attack robot, by "tited for fat" the way eliminates these the fellows who mutinied on the Moon, stemming from this time Earth humanity regarding kind of person robot specialSensitive, this has no recourse the plan is in the situation which keeps secret extremely is formulating the implementation, besides David and the entire unification, the third person had not known.

就在病床上，大卫博士忍着余下的伤痛忧思难眠，辗转往复思来想去，最后终于想出了一个以机器人对付机器人的绝妙方案，当灵感突然显现之后，大卫博士就立刻写成了一份详细的计划报告，然后火速转交给联盟主席全统一，全统一长官看完后，不禁拍案叫绝，并马上授权大卫博士开始实施这项计划，制造大批高性能的绝对反击机器人，以&以牙还牙&的方式清除那些在月球上哗变的家伙们，出于此时地球人类对于类人机器人的特殊敏感，这个迫不得已的方案是在极为保密的情况下制定实施的，除了大卫和全统一之外，没有第三个人知道。

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 shaping, the cutting tool on a shaper reciprocates or moves back and forth while the work is fed automatically towards the tool.

在仿型刨削操作中，仿型刨床上的刀具作往复或前后移动的同时，工件被自动推向刀具。

In shap in g, the cutt in g tool on a shaper reciprocates or moves back and forth while the work is fed automatically towards the tool.

在仿型刨削操作中，仿型刨床上的刀具作往复或前后移动的同时，工件被自动推向刀具。

Since the inertial force of piston depends on its mass when the piston reciprocates at high speed, the tolerance of piston mass must be strictly controlled during design and manufacturing, so as to ensure engine operate smoothly.

活塞重量大小决定其高速往复运动时惯性力的大小，在设计和制造过程中要严格控制活塞重量的公差，以保证装机后发动机运转平稳，理论上公差值越小越好。

When the large rotating arm rotates, the transmission gear is driven to rotate around the fixed gear to rotate the planetary gear, which drives in turn the small rotating arm to rotate in the direction opposite to the large rotating arm, so that the shaft of the small rotating arm reciprocates across the rotation center of the large rotating arm.

当大旋臂旋转时，传动齿轮受到驱动沿固定齿轮周转并带动卫星齿轮转动，卫星齿轮带动小旋臂作与大旋臂反向的旋转，从而使小旋臂上的固定轴随着大、小旋臂的旋转不断往复越过大旋臂的旋心作直线运动。

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。

As the inner and outsider baskets rotate at the same speed, the inner one, pushed by the piston, reciprocates axially and repeatedly. As a result, pusher plate pushes the cake layer in the inner basket to move out of it and then into the outside basket for further separation , a ring layer of cake being formed,while the outside section of the inner basket pushes the cake layer in the outside basket to move continuously out of the outside basket and then discharge it through the slot for scraper.

内、外转鼓同速旋转的同时，在活塞推动下，内转鼓连续轴向往复运动，因而推料盘推动内转鼓滤饼层间歇不断地向外移动排出内转鼓，进入外转鼓进一步分离并形成环形滤饼层，内转鼓外端面则推动外转鼓滤饼层间歇不断地向外移动排出外转鼓，经刮料槽排出机外。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
