Rehoused in the bottom of the furnace two wall and put aside silk brick, the workpiece is heated on the silicon carbide furnace bottom board, the use of the best in the box at the bottom, put a piece of stainless steel plates, this prevents the workpiece impact on the furnace bottom.

安置在炉膛两壁及炉底的搁丝砖上，被加热工件放在炉膛内的碳化硅炉底板上，使用时最好在箱式炉底上放一块不锈钢板，这样可防止工件对炉底板的撞击。

In the robots machining unit, because of the diversity and complexity of the welding parts, the arc welding robot cant weld the complicated part independently, this makes it necessary to have a teaching system that has teaching function.

在机器人加工单元中，由于焊接工件的多样性和复杂性，弧焊机器人不可能独立完成复杂工件的焊接，这就需要具有示教功能的示教系统。

According to the experiences of experiment teaching,we have developed a kind of measuring diameter instrument used in error statistics and analysis in auto lathe of single axle and high precision grinding machine.

根据实验教学的经验，研制了一种用于单轴六角自动车床和高精度通磨无心床做加工误差统计分析的实验教学使用的千分表测径仪，并对几批车削工件和磨削工件进行现场测量，并进行加工误差的统计分析。

It will carry out a series actions of transporting a workpiece, position moving, the work piece in the fixed position in the tongs and clip etc.

它将实现各台机床之间工件转运、位置变化和工件在夹具中的定位和夹紧等一系列动作的柔性自动化。

This article analysed the technology characteristic of great wheel friction spring for clock component 's forming, including the d etermination of operation sequence ,technological analysis of component,determination of blanking pressure and the difficulties of mould design.

本文分析了钟表元件二轮压簧的成型工艺特点，其中包括利用对工件展开图的尺寸计算、工件的工艺分析、冲裁力的计算、模具设计的难点，确定了级进模的排样方案和模具总体结构，而且校核了凸、凹模的强度。

The tool on the cross slide can be driven or fed parallel to or normal to the axis of rotation of the workpiece.

在横向滑板上的刀具在平行于工件旋转轴线方向或在工件旋转轴线的法线方向驱动或进给。

It is one of the most widely used methods to groove and disconnect the workpiece with the cutter,but in the process of cutting the movement of the cross-feed can reduce the working orthogonal clearance,which increases the friction between the tool flank of the cutting tool and the machined surface,and hence results in the break of the workpiece and the working tool.

用切断刀对被加工工件切断或切槽是生产中应用最广泛的加工方法之一，但在切削过程中横向进给运动的影响使刀具工作后角减小，加剧了刀具后刀面与加工表面之间的摩擦，从而会导致工件被挤断，刀具易折断。

The results show that the effects on surface roughness are feed speed, depth of cutting , tool rake angle and parts hardness in turn.

结果表明：工件进给速度对表面粗糙度的影响最大，切削深度和刀具前角次之，工件硬度影响最小。

Firstly the elastic stage of the cutting tool and workpiece in rectangular element is modeled and the relationship between the element node force and element node displacement also deduced.

首先选用矩形单元对刀具和工件弹性阶段进行有限元建模，得出其单元节点力和节点位移之间的关系，然后利用普朗特路斯方程，推导工件材料塑性变形时单元节点力和节点位移之间的关系，并指出金属由弹性变形到塑性变形时其单元刚度矩阵变化的规律，从而为实现金属切削过程的数值模拟提供可靠的理论基础。

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。
