On the condition that the axes of two chain wheels are in the same horizontal plane, the paper considers that the mesh drive of chain and chain wheel is equal to single small angle movement of four-rod mechanism every time on tight side.

在两链轮的回转中心同处一水平面的条件下，视紧边每一时刻链条与链轮的啮合传动为四杆机构作小转角的单向运动，建立起相应的链条速度模型，并据此分析了影响链传动中链条速度波动的因素，得到了一些有益的结

Test results have shown that larger plastic volumetric strain as well as higher growth rate of pore water pressure would be generated in multi-directional shearing than in a single-directional one. Lower resistance of sand to liquefaction was also observed under the rotation of principal stress orientation.

与单向剪切相比，多向剪切会产生额外的塑性体积应变，在不排水条件下孔隙水压力增长的速率较高，特别是在具有主应力轴连续旋转特点的加载条件下，砂土抵抗液化的能力也将更低。

One method is to install a backpressure check valve in the tank line.

This article describes a one-way valve fuel control valve body design and plastic mold design process.

本文说明了加油管单向阀阀体设计及塑料模具设计的全过程。

In addition to the simple, two-ended, unidirectional links which are well-known from HTML, XLink allows more general links, which must not be embedded in the document, can have any number of ends, and can be multidirectional.

XLink在HTML中加入了简单链接、双向链接、单向链接特性，并提供多种类的并不要求嵌入文档中的链接，它具有多目标性和多向性。

Reverse traffic can lead degradation of TCP performance. To resolve this problem, we analyze the impact of reverse traffic carefully, and obtain the relation between reverse traffic and TCP performance. We propose an approach of rate control optimized for unidirectional trip time, and design an algorithm for rate control, called Unidirectional Trip Aware Rate Control, UTARC.

针对反向数据流量会导致TCP性能下降的问题，本文详细研究了反向数据流量对正向数据流应答的影响，揭示了反向数据流量与TCP传输性能之间的联系，提出了面向单向延时优化的速率控制方法，并设计了相应的速率控制算法UTARC。

The green series reinforcing tape is available in unidirectional, bi-ply and tri-ply configurations.

新型增强纤维带有单向，双向和多向系列。

One-way clutch transmission driving force of innovation, to the world automotive industry has left a lot of space on the car clutch is the use of an unprecedented revolution in automotive history of an unprecedented revolution.

单向式动力传递离合器片的创新，给世界汽车业的发展留下了很大的空间，对汽车离合器片的使用是一次空前的革命，也是汽车史上的一次空前的革命。

Once upon a time, I revel in other people's praise among self-considered themselves "Caigaobadou, learning-rich 5 car", so they voted pen from the text of a chapter with a cut, I hope that the works of Yin and flew to the editorial board, one by one Lost rejection with an infinite one-way I came, after many failures, multiple blows, I finally discouraged, even to the point of despair, I feel that life is too harsh to my fate for me too fair, so I complained that sink in despair to get by, wandering in tears.

曾几何时，我陶醉于别人的赞美之中，自认为自己&才高八斗，学富五车&，于是便投笔从文，一篇篇带着我切殷希望的作品向编辑部飞去，一张张带了无限失落的退稿单向我走来，在经历多次失败，多次打击之后，我终于心灰意冷，甚至到了绝望的地步，我觉得生活对我过于苛刻，命运对我太不公平，于是我在抱怨中沉沦，在失望中度日，在泪水中徘徊。

The stress distribution on the cross section of geotextile with a circle or an ellipse or a square hole under uniaxial tension or double-axial tension was calculated with boundary element method program. The results show that the stress concentration appear at the range from the hole side to about 3 times of the hole diameter, and the degree of stress concentration near the hole is related to the shape of the hole, the size of the hole, the position of the hole and the dimension of the specimen.

用边界元法程序分别对开有圆孔或椭圆孔或方孔的土工织物试样在单向与双向拉伸时孔截面上的应力分布情况进行了计算与分析，结果表明：土工织物孔截面上的应力集中出现在距孔边3倍左右的孔径尺寸范围内；孔边附近应力集中的程度与孔的形状、大小、位置及试样的尺寸有关。

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。
