We have incorporated a hydraulically actuated lashing device that either lashes the inner of the lifter to the outer body or detaches the body from the internals of the lifter,thereby not translating the motion from the cam onto the pushrod,"said Nandu Srinivasan,Manager of Advanced Engineering for Engine Air Management Operations at Eaton Corp."

我们已经合并了这种液压驱动装置，即可以使挺柱内部零件和外体紧固，也可以使外体和内部零件分开，当松开时就不会将运动从凸轮传递给出推杆，Nandu Srinivasan，伊顿公司的发动机进气管理工程部门的经理说：&当推杆上受到液压时，它会分开外体，由于没有互相锁定，推杆基本上是在凸轮上，上升下降，就像伸缩望远镜杆一样。&

And a dead metal part that is exposed to contact by persons or that may be grounded, and uninsulated live parts and

在19.7和19.9注明的相对极性非绝缘带电零件之间的间隙，非绝缘带电零件与不带电金属件的

The Dimension detection of mechanical parts has the character of untouching, high speed, high precision. So the detection system of mechanical parts is widely used in automated production.

基于机器视觉的零件检测具有非人工接触，速度快，精度高等特点，因此基于流水线的零件自动化检测系统目前广泛应用于工业自动化生产过程中。

The system is designed according to the mechanism of CAD Standard Part Graphies Files. SQL Server 2000 is selected as the host and construct the database of part liabrary due to characteristic parameter. STEP, viz. ISO 10303, is issued by international standardization organization, and here ,this paper gives the definition of product information model oriented part41 and part44 in STEP and six basic definienses which describe the product information to ensure the information in the product information model correct and shareable . This paper also presents method of creating and extracting product information on engineering draught and product data exchange and integration between CAD system and database manager system.

论文中采用&CAD标准件图形文件机制&，用SQL Server2000数据库建立了零件的特征参数数据库，完成了零件库的特性参数库建库工作；依据国际标准化组织的STEP标准即ISO 10303中的Part41，Part44两部分内容以及STEP标准中描述产品信息的六个基本的类库定义，提出了一种产品信息模型，保证了产品信息模型中信息的正确性和共享性，实现了工程图样中产品管理信息的建立和提取以及数据库系统与图形文件中的管理信息交换与集成。

Surface engineering technologies have been widely applied to disable parts remanufacturing process, especially electric brush plating technology is an important measure for performance upgrade and dimension restore on abraded parts.

表面工程技术在废旧产品失效零件的再制造加工中得到了广泛应用，其中电刷镀技术是进行磨损失效零件性能升级和尺寸恢复的重要手段。

During the development of the CAD system of gear, this paper introduces expert knowledge into procedure of CAD and actualizes the intellectualization in design process, strength analysis.

在齿轮零件CAD系统开发过程中，结合专家系统，将专家知识融入在齿轮零件CAD过程中，实现了设计过程、强度分析的智能化。

The technique of manufacturing transition flange part using SLS technology is introduced,the quality control and solutions of SLS technology in the direct confectioning process of part are analyzed,and the reason and influencing factors of warping deformation is discussed emphatically.

详细介绍了采用选择性激光烧结技术制造过渡法兰实体零件的工艺过程，评论了直接成型零件过程中的质量控制及其解决方法，重点分析了翘曲变形的产生原因和影响因素。

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。

In this model, the manufacturing process can be denoted as the converse sequence of the assembled features.

介绍了基于零件加工特征的逆向装配模型，建立了零件的参数化工艺路线与工艺卡片模型。

Cross-section Imaging Measurement simultaneously digitizes both exterior and interior surfaces of a part, a full data geometry model of a part can be constructed. The technique helps to shorten the design-to-manufacture time and reduce the cost of the product.

采用层去图象法测量技术可以同时测量零件的内外轮廓特征，得到零件的完整数据模型，精度也较高，而且还有助于缩短产品的设计和生产周期，降低生产成本。

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。
