In this paper, a "rigid bar relative movement model" was established to illustrate the traces of the helices in wire ropes. The angular speed of a moving particle of the model was relatives to curvature tensor to derive the curvature components and torsion of helices in multi-layer wire ropes. According to long and thin rod theory of Love and Yen-Chen's theoretical model considered the contact force and frictional force, the force-deformation or force-strain relative of wire in curved wire ropes subjected axial force is derived from the curvature components and curvature increment.

本研究改以刚杆相对运动模型，直接描述钢索中钢绞线轨迹，并且透过角速度类比曲率张量之概念，推导圆弧型多层钢索内部之钢铰线之曲率分量与扭率；之后再依据Love的细长杆理论，辅以Yen-Chen在考虑接触力及摩擦力下所修正之理论模型，以曲率及曲率增量来探讨圆弧型钢索受静态荷重作用下，钢绞线之受力与变形或应变关系。

The tension bar shifts to the left causes steel ball where is at left side distributed diameter changes in a big way, relieved on the cutter bar pulling force, the manipulator then takes out the cutter bar.

拉杆的左移使左端的钢球的分布直径变大，解除了刀杆上的拉力，机械手便取出刀杆。

Which are rotated by an engine at the top and are fitted with a cutting bit at the bottom .

钻杆顶部安装的发动机带动钻杆旋转，它的底部装有钻头。

On the basis of introduction of an epicycloid parameter,δ,an equation is derived for cycloid and its screw surface in screw pump.

本文在引入外摆参量δ的基础上建立了螺杆泵摆线和摆线螺面的方程，并通过对δ的研究，提出了螺杆泵的部分设计理论。

In operation, the screw cylindrical surface and the pump cylinder wall formed between the layer of oil film to prevent direct contact between the metal, so that screw tooth surface wear significantly reduced.

在运行中，螺杆外圆表面和泵缸内壁之间形成的一层油膜，可防止金属之间的直接接触，使螺杆齿面的磨损大大减少。

Firstly,driving forces equations of each driving pair of the whole mechanism are established by combining D'Alembert Principle with virtual displacement Principle.

然后利用虚设机构法建立机构中各杆件的速度、加速度的一、二阶影响系数矩阵，从而解决了少自由度关联机构惯性力求解中各杆件的速度和加速度难以求解的问题。

Due to the transmission angle of the flexible rod deviates from 90°less than others, the pumping unit overcome the "dead angle restricted"problem of the conversional pumping unit and fixed four rods structure.

由于连杆为柔性杆，其传动角偏离90°较小，克服了常规机和固定四杆机构的"死角制约"问题，游梁摆角比常规机可加大30—50%。

In order to meet people in the society's demands, we have designed the small-scale lifting machine, among them, the worm decelerator is a focal point designed the ring.

小型提升机是为了满足社会中人们的需求而设计的，其中，环面蜗杆减速器是设计的重点。它采用了准平行啮合线二次包络环面蜗杆技术。

It analyses the reasons of the declivity happen of one domestic,applies the anchor arm static press pile strengthening the basis,introduces the strengthen construction technology of anchor arm static press pile,adapts the parts cut-off pillar and jacking to correct a error,and practice illustrates that the methods has a good result,can be a reference to the other similar projects.

分析了某民房突然倾斜事故的原因，运用锚杆静压桩进行基础加固，对锚杆静压桩加固施工工艺进行了介绍，采用局部断柱顶升法进行纠偏，实践证明该法效果良好，以供其他类似工程参考借鉴。

As you move these sliders to the right the response becomes non-linear. In this case, the first 50% deflection of your joystick or yoke may only deflect the aircraft's controls by 10%. This will dampen any aircraft movements and desensitize your controls but keep in mind that the remaining 90% of the control surface deflection must take place in the last 50% of joystick travel, in this case.

如果把他们都拉到右边，那么这些控制将变成非线性的（译者注：就是说你把摇杆向一个方向移动很大距离时，才会慢慢开始加速转动），如果拉到100%，那么当你朝一个方向移动50%摇杆的时候，只相当于滑块在0%时的10%的效果。

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。
