工件

Because they have high precision and are fit for measuring soft materials, the easily scathed parts and some surfaces with some useful information.

在表面粗糙度非接触测量中，光学法是测量的主体，其测量精度高，适于对软质材料，易损工件，以及某些带有有用信息的表面进行测量。

Therefore,this paper introduces the repair method of large-size steel casts by sectionalized cold-junction compensation weld technology with nickel-based welding rods.

由于受到结构、外形等因素的影响，对一些大型铸件开裂采用同性热补的方法进行修复和热处理，实施困难且容易导致工件变形，为此介绍了采用镍基焊条分段冷补焊对大型铸钢件进行修复的方法。

And that , there are pits on the surface of the work piece because the high pressure decaling spays is absent[2]. It is easy to be seen that the quality of products is not desirable, the pack rolling of thin sheet processing has far fallen behind the requirement of today, in brief should be already obsolete.

且因为没有高压水除鳞装置，导致工件表面存在小麻点，很容易看到产品质量不合格，薄板叠轧技术已远远落后于今天的需要，简言之，已经落伍了。

The particles of W, Mo, Co were spluttered and deposited on the surface of the steel.

工件表面受轰击作用的过程中温度也得到了提高。

A fastener for installation into a workpiece which may be installed by either a swaging operation or a torquing operation.

一种用于安装到工件(28)上的紧固件(20)，其可以通过模锻操作或者旋拧操作进行安装。

For tilting or swivelling of the workpiece around a defined axis between the final positions 0° and 90°.

对于倾斜或周围的最后立场之间的0 °和90 °界定轴工件回转。

Not only does this allow the table to be trued up at any time, but it ensures that all work-piece placed on the machine will be ground parallel with the table.

这不仅使该表将trued了在任何时间，但它确保所有工件放在机器将与地面平行的表格。

Finally some reasonable truing and dressing parameters and grinding process parameters were proposed.

研究结论可用于分析和预测儿或限制工件表面粗糙度。

Many tones of pressure can be applied to workpieces with little effort while operating the new Mechanical Power Vises, which will never loosen the grip on a workpiece by itself.

仅需小操作力便可对工件施加不同压力；除非用手动方式，否则在夹持过程中压力绝不释泄。

The spindle selects enclosed rolling bearing for supporting; vertical and horizontal drag board are adopted with enclosed rolling rod drive; body guide ways are casted with abrasion-resistance iron quenched with super frequency and milled precisely, and all these contribute to a long-term processing precision and a long lifespan; 5.5KW motor serves as the main motor contribute to a stronger turning capacity and larger rotary speed range; Workpiece clamping is are adopted withed with spring collet, it can also be equipped with hydraulic chuck, four-spindle oil cylinder, pneumatic, hydraulic tail stock.

CK6232数控车床是一款高刚性封密数控车床，特别适宜粗精加工，整机造型稳重大方，全封闭护罩防护，主轴采用精密刚性轴承支撑，纵横向拖板采用精密滚珠丝杆传动，床身导轨采用耐磨铸铁铸造，经超音频淬火及精密磨削，能长期稳定的保证加工精度和使用寿命；主电机选用5.5KW 的电机，使主轴有更强的切削能力和转速范围；工件装夹方式选用弹簧夹头，也可按用户要求配置手动卡盘、液压卡盘，气压、液压尾座。

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。
