工件

A device to measure the diameter or thickness of a piece of work.

量度工件直径或厚度的一种工具。

Adjustable welding Power, which can adjust the gear according to the thickness of work piece.

焊接功率可调，可根据工件厚度调节档位。

Cutting current adjusted from 10A to maximum continuously for different work piece, different thickness and different cutting speed, good cutting surface.

切割电流从10A到最大输出电流连续可调，可满足不同工件材料、厚度和切割速度的要求，切口美观。

Then thickness of the work piece, location of the locator, frequency of the sinusoidal load were changed, and end milling simulation was conducted. The stress, displacement, velocity, acceleration from different cases was compared.

同时通过改变工件厚度、改变定位块位置、改变正弦载荷的频率等参数，分别对各种情况进行仿真，并对获得的应力、位移、速度、加速度的变化进行了比较分析。

The objective of this study was to analyze the square cup stretching process by using the dynamic explicit finite element analytical program, which was based on the Updated Lagrangian Formulation and elasto-plastic theory. Simulation results included the deformation and crack propagation history, the variation of the work piece thickness, the Forming Limit Diagram, and the relationship between punch load and punch stroke. A set of tools was designed for the square-cup stretching experiment to verify the reliability of the program.

中文摘要本文采用显性动态有限元素法，结合材料弹塑性理论，发展出一套三维增量型之有限元素分析程式，进行金属板材方杯拉伸成形制程及破裂之分析，并探讨方杯拉伸成形历程及裂纹成长历程、工件厚度变化、成形极限图(Forming Limit Diagram， FLD)，及冲头负荷与冲程关系，并设计一组方形冲模来进行方杯拉伸成形实验，以验证程式的可信度。

The paper begins with the analysis of measurement errors of parallelism of dovetail slots,then studies the working principle and the ratio of amplification for dial test indicator .

从分析工件燕尾槽平行度测量误差入手，深入研究杠杆千分表工作原理和传动放大比公式，讨论了产生误差的各种因素，并提出了校正误差的相应方法

It was necessary to strictly adjust the machine tool's taper parameter when the work pieces had taper by using the numerical control precision WEDM machine,and introduced the basic procedure and method on parameter adjustment by using the trigonometric function.

数控精密线切割在加工带有锥度的工件时，需对机床的锥度参数进行严格的校正，应用三角函数关系详细论述了机床校正的基本过程和方法。

For grinding work pieces of easy to burn and high precision to be requested such as tap gauge etc.

磨削易烧伤或精度要求高的工件，如丝锥、量规等

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。
