工件

Chemical heat treatment by changing the workpiece surface chemical composition, structure and properties of metal heat treatment process.

化学热处理是通过改变工件表层化学成分、组织和性能的金属热处理工艺。

By using one chip and one apical clamping mode, tailstock has elastic .

采用托架避免工件产生很大的摆动，垫块具有消振的作用。

When a ferromagnetism items is under the application of stress, the phenomenon that the tangential component of magnetic leakage field has maximum value and that the normal component of magnetic leakage field changes polarity and acquires zero value at the stress concentration zone will take place.

铁磁性工件在受到应力作用时，在应力集中处会有漏磁场的切向分量出现最大值、同时法向分量改变符号且过零值点的现象。

According to the effective field expression, the phenomenon that the tangential component of magnetic leakage field has maximum value and the normal component of magnetic leakage field acquires zero value at the stress concentration zone of positive magnetostriction ferromagnetic materials is explained theoretically.

它的物理基础是，铁磁性工件在运行时，受工作载荷和地球磁场的共同作用，在应力和变形集中区域内会发生具有磁致伸缩性质的磁畴组织定向和不可逆的重新取向，而且这种磁状态的不可逆变化在工作载荷消除后不仅会保留，还与最大作用应力

The point of the probe is placed on the work and the temperature is read from the scale.

将探针放在待测量的工件上，然后从刻度上读取温度读数。

Machining is sometimes done on the actual surfaces as opposed to tessellated surfaces to obtain a higher quality output. However, quality problems sometimes occur with high-speed machining, as the material can overheat, cracks can develop and the material can move.

为了得到更高质量的零件，高速加工有时是在实际工件表面上而不是网格状表面进行的，但是在材料过热、裂缝扩展以及移除材料过程中，高速加工有时也会出现质量问题。

This is a work to be tested.

这是一个待实验的工件。

The optical theodolite can be used in measuring the shape and position of a super-big workpiece.

用光学经纬仪可以对超大工件的形状和位置进行检测。

Is TIG welding the best welding process for the job at hand?

TIG焊是手头工件最好的焊接工艺吗？

Tolerance is the amount of variation permitted in the part or the total variation allowed in a given dimension.

公差是工件允许的偏差值或所给尺寸的全部偏差值总和。

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。
