工件

The size of the common due window is always a decision variable.

工件提前和延误的惩罚费用因子是任意的，并且在最小化的总费用中考虑了时间窗位置e的选取费用。

In these two problems,the job processing time is a linear decreasing function of its starting time,the objective is to minimize the total completion time .

在这两个问题中，工件加工时间均为开工时间的线性递减函数，目标函数为极小化总完工时间。

FEM is used to calculate precisely the ela stic deflection error of the system under the condition that t...

在车削加工工件尺寸及形状皆连续动态变化时，应用有限元方法准确计算出工艺系统因弹性变形所引起的误差。

In order to help to analyze the limit degree of freedom when a component is being positioned.

以帮助对工件定位时限制自由度的分析。

Sawing machinery with fixed blade during cutting, having a fixed bed or support with manual feed of the workpiece or with a demountable power feed

有固定刀片的锯切机械在切割时，有固定的机床，或由人工送纸的工件

In the article introducedthe work piece in clamps the concrete center the locate mode, locatesthe part and the detent mechanism choice, and clamps the organizationthe choice and the design.

文中介绍了工件在夹具体中的定位方式，定位元件与定位机构的选择，及夹紧机构的选择与设计。

It is assumed that the deterioration function is a linear function.

在这类问题中，工件的恶化函数为线性函数。

In wire-cutting manufacturing of the top and bottom different curve,accomplishing cutting way of ellipse bias changing curved surface which between two plane curve into developable surface in order to calculate NC program of four axis ganging.

在上下异型工件的线切割加工中，宜采用椭圆偏置切割法，即将上、下两平面曲线间的曲面变成可展直纹面，进而计算四轴联动的数控程序，可保障加工的效率与效益。

This is maximum diameter of work that can be rotated on a lathe.

这是在车床上能够旋转的工件的最大尺寸。

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。
