往复的

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。

A proven technology that weens us off fossil fuels and in some ways performs better than over complex reciprocating petroleum engines and transmissions.

行之有效的技术， weens我们小康矿物燃料和在某些方面的表现优于复杂往复石油引擎和传输。

However, it is possible to eliminate this backlash in ball screw systems, making possible to ensure accurate positioning in reversing applications.

然而，在滚珠丝杠的传动系统中，消除回程间隙成为了可能。这样可以保证了往复定位的精度。

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。

Also in the spring reaction force, the closing cylinder intake or exhaust port, back and forth through the return to work.

又在弹簧的反作用力下，关闭汽缸的进气口，或排气口，循返往复地工作。

The shaper tool straight line advance and return movement is host motion when plane chop, that workpiece moves in the perpendicularity and host direction of motion intermittence is to feed motion.

刨削时，刨刀的直线往复运动是主运动，工件在垂直与主运动方向的间歇移动是进给运动。

Planer is to adopt a working table to compose linear motion moving back and forth with workpiece but then , the cutter assumes but blank feed the motion moving assigning a form transversely.

而龙门刨床则是采用工作台带着工件作往复直线运动，而刀具作间歇的横向进给运动的运动分配形式。

The variation of friction force between piston ring and cylinder liner,which may exert great influence on the engine operation, is very complicated because of the reciprocation of piston assembly.

摘 要：由于往复运动特性，工作状态中活塞环缸套的动态摩擦力非常复杂，而且对发动机的工作状况有重要影响。

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。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
