工件

Since the device is armless, and the data transmission process is wire?less, the user can move freely around the part.

由于此设备是无支撑无支架结构，数据传输也是无线的，所以用户可以自由围绕着待测工件移动扫描设备。

Total freedom of movement 完全移动自如 Since the device is armless, and the data transmission process is wireless, the user can move freely around the part.

由于此设备是无支撑无支架结构，数据传输也是无线的，所以用户可以自由围绕着待测工件移动扫描设备。

The closed loop control system simulation was carried out based on ARX model and BP neural network prediction model to prove the feasibility of this method.

为了进一步验证该方法的有效性，设计了梯形、渐变哑铃形和突变哑铃形三种不同形状的工件，以代表实际焊接过程中不同的散热条件。

Big bore of the spindle widens the processing range for workpiece. Dead stop button and safety device make the lathe more safe and reliable. The bed adopts high rigidity cast iron and bedways are hardened and precision-ground with durability. It has low noise and is suitable and proper for human's performance.

主轴通孔直径大，扩大了加工工件范围；设有急停按钮和保险机构，使机床更加安全可靠；床身采用高强度铸铁，导轨表面淬火后精磨、经久耐用；机床噪音低，宜人性好。

Her job at the factory is to calculate the size of work pieces with a caliper gauge.

她在厂里的工作就是，每天拿着卡规测量工件的尺寸。

Deadlock control is proposed. Depended on the route of parts, used ObjectOriented technology, the static structure of machines is capsulated in a object subnet, is represented by a big place, a simplified colored Petri net is proposed.

基于系统中工件对机床的需求关系，利用面向对象技术把机床的静态结构封装为一个对象子网，用一个大位置表示一机床，提出了简化着色Petri网模型。

The research indicated that the main electric particles forming guiding discharge channel were the electrons released from the process of the breaking up of the negative ions. During 10 microseconds after the laser pulse, the electrode also could guide discharge effectively; and it suggested the new conception of the electrode erosion, and developed new-type running disk electrode, which could discharge for a million times in atmosphere. It also suggested methods of the texturing roller of besmearing with oil film and cathodal discharge in processing. The research of the texturing roller indicated that roughness of 14 microns and the intensified depth of over 200 microns could be got.

研究表明：形成诱导放电通道的带电粒子主要是负离子解离过程释放的电子，在激光脉冲结束后10微秒内，电极都能有效诱导放电；提出了电极损耗的新概念，并研制了新型转动圆盘电极，可在大气中完成上百万次放电，提出了加工过程中负极性放电、工件表面涂介质薄膜放电的毛化工艺方法；并用之对轧辊试件进行了毛化工艺研究，毛化粗糙度可达14微米，强化深度大于200微米。

It emphatically introduces the defination method about the workpiece center height of centerless machine, and it has use for reference in improving the quality problem of the roundness of bearing in the process of centerless grinder.

着重介绍了无心磨床工件中心高的确定方法，对如何提高无心磨加工过程中的圆度质量问题具有一定借鉴意义。

The system uses PLC procedure control, start-up, forward or backward soldering gun, arc starting, workpiece circumgyration, etc full welding process all can complete automatically.

系统采用 PLC 程序控制，启动、进退枪、引弧、工件旋转等焊接全过程均能自动完成。

Comparing with common side hybrid laser-arc welding, coaxially combined laser beam and arc can provide a symmetrical circular thermal source on the workpiece surface, which is convenient for 3-D welding.

与目前常用的旁轴激光-电弧复合焊相比，激光-电弧同轴复合可以在工件表面提供对称热源，焊接质量不受焊接方向影响而适于三维焊接。

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。
