This paper dealed with image data acquisition for automatic inspection of surface cracks of workpieces .

简要介绍了工件表面裂纹自动检测的图象采集方法。

Bnd it could be used as the reference in the large scale production of similar workpieces.

本文介绍的模具实例结构简单实用，使用方便可靠，对类似工件的大批量存产具后一定的参考效用。

Used to deposit a dark chromium layer over bright nickel, satin nickel, nickel-iron or white bronze.

革命性的合金电镀工艺，代替装饰性铬电镀于光亮镍工件。

Examples of open-shop problem include health examination and the operation of car maintenance. Scheduling problem with no-wait constraints occur in many industries. For instance, in hot metal rolling industries, where the heated metal has to undergo a series of operations at continuously high temperatures before it is cooled in order to prevent defects.

生产过程中的排序往往受到产品生产的特性或者生产技术的限制，所以会产生不同的约束情况，例如：无等待时间是化学、石油工业和冶金工业的特色；阻塞指的是缓存能力受到限制或者没有缓存的情况，最常见的是利用机器人进行夹取工件的作业。

Be sure your measurement is taken between the black lines on the shanks.

确保测量的是各工件上黑线之间的距离。

Therefore, Compared with the traditional oxygen-acetylene flame spray technology, the advantages of RFSS lied in simultaneous synteesis and deposition of expensive coating materials from an in-situ reaction of cheap raw materials.

在到达工件表面时，反应已基本结束。因此，与传统热喷涂相比，反应火焰喷涂的优势在于，利用廉价原料一步合成、沉积比较昂贵的涂层材料。

It is the filling material in argon arc welding and oxygen-acetylene gas welding for the aluminum alloy weldment expect the Al-Mg alloy, it can get the better effect in deal with the heat crack of the strengthening Al-alloy.

HS311 AWS ER4043 除铝镁合金以外的的铝合金工件和铸铁氩弧焊及氧-乙炔气焊时作为填充材料，特别对易产生热裂缝的热处理强化铝合金，可获得较好的效果。

Variations in the shapes of the cutting tool influence tool life, surface finish of the workpiece, and the amount of force required to shear a chip from the parent metal.

刀具在形状上的变化影响着刀具的寿命，成型工件的表面状况，和从基材上切下碎屑所需的力。

Hear a chip from the parent metal.

刀具在形状上的变化影响着刀具的寿命，成型工件的表面状况，和从基材上切下碎屑所需的力。

Machining requires two kinds of tooling; working-holding devices and cutting tooling, such as drills and reamers.

机加工需要两种工夹具，工件夹持装置与刀具如钻头与铰刀。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
