There are four phases and dozens of parameters in preheating flash butt welding technology used for great section workpiece's welding.

文摘：用于焊接大截面工件的预热闪光焊工艺包括四个阶段。

After studying the flash butt welding thoroughly, using the most popular WINDOWS application develop technology at present, programming language C Builder, assemble language and Microsoft Access, a software of flash butt welding machine of great section workpiece is developed.

通过对闪光对焊工艺的深入研究，结合当前最为流行的WINDOWS应用程序开发技术，利用程序设计语言C Builder、汇编语言和商用关系数据库MicrosoftAccess，开发了大截面工件闪光焊机的过程控制与数据管理软件

By means of using a disc cutter with a concave end instead of traditional ball-ended or flat-ended ones,and adjusting the cutter axis to move relatively to the component being machined according to some special rules,the envelop formed by the trace of the tool-nose in each pass and the required surface have the same derivatives up to the second order in the plane normal to the feeding direction.

采用二阶密切曲率法，即采用中凹的盘形铣刀取代传统的球头或鼓形铣刀，在每一行程中让刀具轴线相对于工件按特定的规律摆动，使得在垂直于进给方向的法截面中，由刀尖轨迹形成的包络面与理论曲面的法截线具有相同的1阶？

Converted the cutting force and gravities of every parts of the machine tool on the integration slant machine bed for a typical condition,and gain load parameters on the integration slant machine bed when cutting positions are located at both ends and the middle of the work-piece.

论文对一体斜床身进行三维实体建模，把典型工况下的切削力、床身上各机床零件的重力折算到一体斜床身上，得到切削位置分别位于工件两端和中间时一体斜床身载荷参数。

In this paper,a three-dimensional model of integration slant machine bed was established.When cutting force and gravities of all parts of the machine tool are converted under a typical condition,bed load parameters on different cutting positions are gained.

对一体式斜床身进行三维实体建模，把典型工况下的切削力、床身上各机床零件的重力折算到一体式斜床身上，得到切削位置分别位于工件两端和中间时一体式斜床身载荷参数。

To improve the quality of grinded workpieces, on-line measuring technology is adopted on NC grinding machine to form a closed-loop grinding system.

为了进一步提高工件磨削的质量，在线检测技术被用于磨床磨削系统，以构成一个闭环控制系统。

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。
