扭转

Atfirst,stress and displacement at the end of collinear crucks are calculated by elasticity me-chanical method,then general solution of twist force at the end of collinear cracks is givenby rotation theory,single crack and double cracks are discussed emphatically.

本文计算并讨论了忽视旋转的传统理论所不能给出的裂纹端部场与场源的相互作用，首先利用弹性力学方法计算了共线裂纹组端部的应力场及位移场，然后应用旋转理论给出共线裂纹组端部的扭转力通解，对单裂纹和双裂纹情形做了重点讨论。

When we consider the procedures that are routine today and how they might have been viewed in the 1700s, we can begin to see how difficult it is to make a well-founded argument that future medical technology will never be able to reverse the injuries that occur during cryonic suspension.

当我们考虑到今天那些所例行的程序与在1700年它们被如何看待时，我们能察觉到，建立一个确凿的论点，断言未来的医疗技术将永远无法扭转发生在冷冻暂停时的伤害，是多么的困难。

The Acropolis appears to be a conservation success story. Thirty-five years ago, following the return of democracy, Greece launched an ambitious restoration project at the ancient temple site, reversing decades of pollution damage and treatment debacles that ended up causing more problems than they solved.

雅典卫城似乎是一个成功的故事。35年前，随着民主的回归，希腊推出了一项雄心勃勃的修复工程，想扭转污染的损害，结果却是造成了比几十年前更严重的问题。

Foreign bone china's shapes are novelty, decors are exquisite and colors are flamboyant, while our products seem to be stale and rough, and imitate each other much, caused the goods to be in the state of low competition, which we must turn the scale as soon as possible.

国外骨质瓷器型新颖、花面细腻、色彩艳丽，相比之下我们的产品则显得陈旧粗糙，而且互相模仿现象严重，导致产品竞争力不强，这种现象必须尽快扭转。

This was a reversal of previous denials by the London government that CIA flights had landed on British territory.

这是一个扭转以往的否认，由伦敦政府认为，美国中央情报局的航班已降落在英国领土。

This began when London reclaimed the Eurobond market from America, a result of American tax changes that, critics say, drove the business offshore.

这一扭转起自伦敦从美国手里重夺欧洲债券市场，有批评者认为，这正是当时美国税收政策的变化驱使相关业务流向他国导致的。

The effect of the expansion and the anti-thrust ring on the stress and deformation of the spiral case structure are analyzed respectively. It is found that the presence of expansion reduces in large extent the stiffness of the spiral case as a supporting structure of the turbine. It affects the safe stability of the hydro generator.

3通过对是否设置伸缩节与止推环的方案对比分析，发现设置伸缩节在一定程度上降低了流道系统的轴向刚度和抗扭转刚度，影响水电机组的安全稳定运行，设计中应予以重视。

"That is only the beginning", she said and turned around to face the wall.

&这仅仅是个开始&，她说，和扭转面对墙。

In this paper we have characterized the structure of various twist interfaces which are composed of (001 ),(011),(111 )-oriented semi-infinite crystals of four face-centered cubic metals Ag, Au, Al, Cu and (001),-oriented semi-infinite crystals of Si respectively with the coincidence site lattice, and calculated their energy with Modified Embedded Atom Method.

本文采用重合位置点阵的方法表征了Ag、Au、Al和Cu四种面心立方金属的(001)、(011)和(111)取向的半无穷大晶体分别与Si的(001)和(111)取向的半无穷大晶体构成的扭转界面的结构，并应用改进嵌入原子法计算了它们的能量。

The same goes for Brazil, Uruguay, Costa Rica and a handful of other Latin American and Caribbean nations that have decided in the 21st century to stop running their societies like medieval fiefdoms.

巴西、乌拉圭、哥斯达黎加和其它一些拉美和加勒比海国家都已决定，在21世纪扭转象中世纪封建社会那样的社会运行机制。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
