需要翻译一篇英语短文,是机械类的。求帮助!给高分!

压毛刺,这术语独特的冲裁和尖锐的工业,它被人们广泛接受。

角落的角落——相交所形成的三个或三个以上的表面通常是圆形二到五倍所形成的两个平面边缘。因为这个原因,它是重要的区分这两种类型的十字路口。

边缘——边缘和角条件甚至被经常使用词典编纂者互换,但去毛刺工艺的影响的棱角明显不同。

破坏——边休息边通常也包含或者一个半径或槽。它通常是假定chamfers应当毛刺自由。需要注意的是,生产过程最毛刺半径并不是一个真正的半径,但它足够近,切实可行的对策措施。


谁能帮我翻译一下机械专业的英语文章,不要机译,谢谢!

Centrifugal force principles are also used in common appliances such as clothes dryers and in devices to control motor speeds and accelerate moving machines.

Centripetal force causes an object to travel in circular path.
离心原理也可普遍应用于设备中,如:干衣机、马达转速控制器和加速设备。向心力使设备能做圆周运动。

This action is caused by the continuous application of forces, which tend to pull the object to the center. In other words, the inward force, which resists

the centrifugal force, is called the centripetal force.
这种运动依靠力的不间断施加来实现,这个力趋向于把物体拉向中心。或者说是对抗离心力的向内的力,这就是向心力。

The centripetal force of objects spinning at a constant rate produces an acceleration toward the center which is equal and opposite to the centrifugal force.
做恒速圆周运动的物体的向心力产生一个向心加速度,它的大小与离心力相等,方向相反。

The materials used in the construction of rapidly moving machine parts and mechanisms must be structurally strong enough to provide the centripetal force

required to hold the parts to a circular path.
!!!!!此段有误,或能力不足,翻译不出来。!!!!!

At the same time, the materials must be able to withstand the centrifugal force, which tends to pull the parts apart. Motion and the basic laws, which affect

motion, are important considerations because of the numerous applications of these principles to produce work through mechanical devices.
同时,材料要承受得住有分离撕裂物体的离心力。
运动形式和基本定律影响运动,应加以重视,因为很多机械装置是建立在基本定律的基础之上的。
There are two primary mechanical motions: rotary and rectilinear. These terms suggest that rotary motion is a circular movement around a center line and

rectilinear motion is a straight line motion.
有两种基本的机械运动:旋转运动和直线运动。旋转运动是围绕一条中心线的圆周运动,直线运动是在直线上的运动。

For either rotary or rectilinear motion, it is possible, with added mechanical devices, to produce other forms of motion such as intermittent motion and

reciprocating motion.
无论圆周运动还是直线运动,通过增加机械装置可以产生其他形式的运动,如:间歇运动和往复运动。

Rotary Motion: The motion that is commonly transmitted is rotary motion. This type of motion may be produced with hand tools or power tools. Rotary motion is

required to drill holes, turn parts in a lathe, mill surfaces, or drive a generator or fan belt.
圆周运动:圆周运动是常用的传送运动。这种运动可以通过手动工具或动力工具产生。圆周运动可用于钻孔、车削、铣平面或者驱动发电机或风扇。

Rectilinear Motion: The feed of a tool on a lathe, the cutting of steel on a power saw, or the shaping of materials are all situations in which rectilinear

or straight line motion produces work.
直线运动:车刀的进给,在锯床上切割钢铁,或材料的成型都是直线运动的应用。

In each of these situations a part or mechanism is used to change rotary motion to straight-line motion. The screw of a micrometer and the threads in a nut

are still other applications where the direction of motion is changes from rotary to rectilinear.
在上述每种运动中,都有一个零件或机构用来将圆周运动转化为直线运动。千分尺和螺母上的螺纹是另一种将圆周运动转化为直线运动的应用。

Harmonic and Intermittent Motion: Any simple vibration, such as the regular back, and forth movement of the end of a pendulum, is simple harmonic motion.

However, many manufacturing processes require intermittent or irregular motion.
简谐运动和间歇运动:任何简单的振动,如钟摆的周期前后运动,就是简单的简谐运动。然而,很多制造工艺需求间歇运动或不规则运动。

For example, the fast return stroke of a power hacksaw or shaper ram is desirable because no cutting is done on the return stroke. Therefore, as more time is

saved in returning the cutting tool to the working position, the less expensive is the operation.
例如,快速回程电动弓锯是高效的,因为在回程中没有切削作用。所以,回程时间越短,越经济。

The combinations of rotary and rectilinear motion obtainable are unlimited because of the large variety of parts such as gears, cams, pulleys, screws, links,

and belts, which can be combined in many arrangements.
圆周运动和直线运动的组合有无限种可能,因为大量的零件,如:齿轮、凸轮、滑轮、螺纹、连杆和皮带,能以多种形式组合起来。

   2015年11月14日雅思写作真题解析    Task 1   A卷:描述了一个地方在建造水电站前后的变化   B卷:饼图,艺术生毕业之后的工作选择    分析:   本次的小作文又一次考查了AB卷。考察每种类型的图的概率都上升了,考生以后准备题型要全面,临时抱佛脚押题越来越难了。A卷题目是历史变迁类的地图题,时态为一般过去时和现在完成时。A卷配图是根据网友回忆所做,范文仅供参考。B卷因为缺少网友回忆和数据,没有图提供,考查的是许久未出现的饼图,为静态图,用过去时。
