Through analyzing and testing the process of carbonizing pump barrel ,the relationship between induction hardening parampters,hole size and body hardness was summarized.

通过对渗碳泵筒加工工艺的分析和试验，总结出中频感应淬火工艺参数和工件内孔尺寸、基体硬度之间的对应关系，为泵筒生产时内孔尺寸精珩余量的确定提供了依据。

The invention also has the advantages of lower short circuiting rate of the processing, good stability, high removal rate of materials, good quality of treatment surface, and being in accordance with the trend of green manufacturing.

本发明的优点是：加工短路率低，稳定性好，材料去除率高，工件表面质量好，符合绿色制造潮流。

To this end, during machining, must be the workpiece clamping good.

为此，在进行机械加工前，先要将工件装夹好。

The author has brought forward new classing manner which is different from the old one. The author also found evaluate target for every type of workshop. The author bring forward the conception of convey rules, and use it as one of the evaluate target. The conception is useful in solving the problem of multi-workpiece workshop layout.

本文提出了与传统分类方式不同的车间分类方式，为每种车间建立了相应的评价指标体系，首次提出了搬运矩概念，并将搬运矩作为一个评价指标列入指标体系中，这就很好的解决了生产多种工件的车间设备布局优化问题。

The crystallization ability of the coating is controlled by the coating component and it can be adjusted in order to avoid completely crystallizing.

通过XRD考察了涂层在热加工完成后的结晶性能，发现在工件的冷却过程中，涂层中会产生结晶相，结晶有助于涂层的剥落。

When heating,the part was exposed in the air,so it's easier to be oxdized,decarburized,which effect the surface characters of part.

金属加热时，工件暴露在空气中，常常发生氧化、脱碳(即钢铁零件表面碳含量降低)，这对于热处理后零件的表面性能有很不利的影响。

And the technology of CAD characteristic discerns and get the data is keys among them .

它们都要求能自动识别CA D设计图纸并生成工件的三维图形，而这其中CAD特征识别与数据提取技术即坐标测量机能直接从CAD图纸中获得零件的几何特征是其中的关键。

By analyzing the forging process of double frustums sucker rod and using rigid visco-plastic material model and 3-D coupled FE simulation, the whole forging procedure are analyzed and simulated with finite element analysis software DEFORM. The results indicate the inner stress field, strain field, metal flowing law and forging travel-load curve during the forming procedure. The forming statuses, causation of defect of workpiece are predicted and so on.

通过对抽油杆镦锻工艺的分析，并采用刚粘塑性材料模型与有限元耦合的方法，运用有限元分析软件DEFORM-3D对双圆台抽油杆的成形过程进行了模拟，获得了成形过程中的内部应力、应变、金属流动规律及行程――载荷曲线，预测分析了工件成形状况、可能产生的主要缺陷的形式、部位和原因。

Quite a mouthful isn't it? To put it simply, post-process gaging systems direct production machinery and automatically adjust for tolerance variations before a bad part is made.

简单的说，反馈处理测量系统能够在加工过程中测量工件的尺寸情况，根据这些尺寸及时调整后序的公差控制，从而避免超差件的产生。

It provides good help,and imitates operating interface and processing movement of cutting tools.

该系统模拟了数控铣床的操作界面、刀具的运动过程以及工件加工后的效果，并提供了友好的帮助系统。

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。
