Copying Milling Machine: A profile of workpiece for the milling process.

6仿形铣床：对工件进行仿形加工的铣床。

The steady state and transient components of the current injection artifact are nulled with the DC and transient balance controls.

目前注射工件的稳态和瞬态成分就被删除了与 DC 和瞬态平衡控制。

X-ray diffraction. The microstructure and cross section microhardness of nitrided layers were observed and analyzed by optical microscope and microhardness tester.

在一定的工件表面温度下，粒子表面物理吸附的氮原子发生脱附，脱附下来的活性氮原子渗入基体的内部，形成渗氮层。

The workpiece with a chrome, zinc, cadmium plating, copper, tin, lead, gold plating imitation oxide, zinc phosphate salt processing, pickling treatment, electrolytic processing capacity.

具有对工件进行镀铬、镀锌、镀镉、镀铜、镀锡、铅、仿金电镀、氧化、锌磷盐处理、酸洗处理、电解加工等能力。

Because of the difference of the workpieces,the height of the polisher must be adjustable,which is realized by use of pulley block .

介绍了木工用抛光机的主体结构，由于被抛光的工件高度不同，要求抛光机的机头高度可以上下调整，本设计中采用滑轮组实现了这一功能。

In Taiwan for more than 30 years experience in the heat treatment, its projects around the aerospace industry, defense industry, automobile industry, and other difficult part, and accumulated a metal heat treatment of materials science and experience, the key to the development of high-performance components, Jimi Ya sen ( 20 roller mill) work roll is a representative sample.

在台湾30多年的热处理经验，其项目遍及航太工业、国防工业、汽车工业等高难度工件，并累积了金属材料科学的热处理经验，更不断地发展高性能关键性组件，仙吉米亚（20辊轧机）工作辊是一代表性范例。

In order to reduce geometric errors between motion trajectory and work piece curve,this paper present a means of controlling trajectory motion law to replace traditional position control.

为了减小刀具运动轨迹与工件几何曲线的误差，提出将传统的位置控制改为物理运动规律控制，即建立数控机床的运动模型，分析被加工轮廓的曲线方程、加工工艺运动要求与刀具加工运动的合成或分解关系，推导出轨迹运动方程组。

The implanted thermocouple cannot measure the workpiece temperature directly because the thermocouple junction is away from the workpiece. Infrared radiation pyrometer can response fast.

也不宜采用在刀具内埋置人工热电偶的方法，因为埋置热电偶时，热电偶接点与刀尖多少有些距离，而刀尖处的温度梯度较大，因而不能直接测量工件的温度。

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。
