往复

Therefore the plunger is in both rectilinear motion and circular motion.

柱塞在运动中既做往复直线运动，同时还做圆周运动，故磨损均匀，使用寿命延长。

The cyclic softening was analyzed under TEM thatit is related to heterogeneity of plastic deformation. The softening of the steelstested is caused by the formation or the dislocation cell structure with low densityand low internal stress, and by the redissolution of fine carbides into matrix.

试验钢的软化是由于在循环变形中位错结构转变成低密度、低内应力的位错胞状组织，以及细小碳化物在位错往复切割下碎化而重新回溶引起的。

To move in or as if in a cycle . a regular variation in value about a mean.

相对与平衡位置的一种往复性周期运动。

However, it is impossible to foresee the decoder state within the round-trip delay time. Consequently, to prevent such possible error effects, we further enhance SBET by ROPE. The encoder will recursively keep estimating the expected decoder pixel distortion. The distortion of frame reconstruction at the decoding side includes the quantization error, propagation error, and concealment error.

然而，在往复延迟时间内的情况则是无法预知的，因此为防范可能的错误蔓延，我们提出将递回式最佳像素预估法与其进一步结合应用，让编码端用递回的方式计算出解码端像素失真量的期望值，此失真量会包含量化失真、错误蔓延的错误和错误隐藏所带来的错误。

Such mutterings back and forth Crawling, creeping, here May not escape from loss, but you Are not an accomplice Despite being the initiator of sanguineous desire You do not know about this secretly planned carinival that breaks after disillusion Vows smash into pieces, besides love Nothing achieves survival Fragments, pave the cobbled road Whether in heaven or in hell, judges Face the rigid silence of those dead After the fall A rolling wave puts on its coat, not a stroke of tear stains

如此往复的呢喃着匍匐，蠕动，在这里未必就可以不失去，但你不是同谋尽管成为血红色欲望的始作俑者你并不清楚，这秘密策划的极度狂欢，幻灭之后起誓接连破碎，除爱情之外亦未能幸免于难瓦解的，铺成了碎石子路无论通向地狱或天堂，审判者都面临着罹难人陨落之后最坚忍的沉静滚动的浪潮穿上外套，划不出一道泪痕

Screen installed inside the slide, slide installed on the bracket, in supporting the screen border on the electromagnetic vibration device, so that screen back and forth movement along the rail.

筛内安装有滑轨，滑轨安装在支架上，在筛的边框上支撑着电磁震动装置，使筛网沿滑轨往复运动。

We take sech form ansatz and solve the CNLS equations through variational approach. We obtain the analytical expression of nonlinear coupling term, which is in the lagrangian of CNLS. We apply a potential well model to analyze the interaction properties of self-trapping beams in detail, the results show that the interaction do not change the profile of the beams, two beams keep oscillating around their collective center periodically. The amplitude and period of this oscillation are both determined by initial separation of two beams.

我们采用Sech函数为试探函数，用变分法求解CNLS方程，（1）给出了CNLS方程所对应的拉格朗日中的非线性耦合项的解析表达，（2）利用势阱模型详细分析两自陷光束之间相互作用的特性，结果表明，相互作用没有改变孤子的形态，它们分别在与传播方向垂直的方向上绕它们的公共中心做往复振动，振动幅度及周期都取决于两光束的初始分隔。

In other words, they fear that worry can help lead to a self fulfilling prophecy which just causes more worry which makes them worry that much more which just puts them into a viscous worry cycle.

也就是说，他们害怕忧虑促使预言自然成真，而这预言又引起新一轮的忧虑产生，如此往复形成一个环环相扣的忧虑圈。

The results show that the tide of Shenzhen Bay is mainly irregular semidiurnal and the horizontal tidal current is reversing current, mainly in southwest-northeast direction.

计算结果表明：深圳湾海域属不正规半日潮，水平潮流具有明显的往复流性质，主要呈西南－东北走向；落潮流速略大于涨潮流速；受地形及陆地河流径流的影响，湾中到湾口及航道附近流速较大，湾顶和靠近香港的滩涂部分流速较小；深圳湾余流场较弱，余流流向指向湾外：整个深圳湾水交换较弱，海域自净能力较差。

Product circumstances: Company main products are two distinct types: 1, chemical fiber textile equipment, including a variety of accessories such as: chuck shaft, reciprocating shafts, roller shafts and other products more than 2,000 species, JRT1 ~ JRT16 series winding machine, of which 16 JRT16 melt-spinning spandex spindles winding machine for the national patent product, JRT1 Jilin winding head for high-tech products, all kinds of chemical fiber textile engineering in three production lines; 2, and the MTR railway passenger vehicles Valves products, such as: height adjustment valve, pressure valve, connecting rod and so on.

产品情况：公司主要产品分两大类：1、化纤纺织设备，其中各种配件如：卡盘轴、往复轴、槽辊等产品2000余种，JRT1~JRT16系列卷绕机，其中JRT16十六锭熔纺氨纶卷绕机为国家专利产品，JRT1卷绕头为吉林省高新技术产品，各种化纤纺织工程生产线三种；2、铁路客车及地铁车辆上的阀类产品，如：高度调整阀，差压阀、连杆等。

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。
