By this device, we can determine the symmetry center of the parts and then locate the parts.

通过设计特定的辅助装置，确定零件的对称中心，并将其定位。

If the screwed fastening piece and solid piece are longitudinally sectioned and the cut plane goes through the center of symmetry, these parts are represented as though they were not sectioned.

对于螺纹紧固件及实心件若按纵向剖切且剖切平面通过其对称中心时，这些零件按不剖画出。

Results have theoretical significance to the design and optimization of cladding parts and to more applications of the cermet cladding material.

文中的研究结果对金属陶瓷硬质覆层零件的设计、优化以及金属陶瓷硬质覆层材料的进一步推广应用具有重要的理论指导意义。

Cermet cladding material is a new kind of composite material with high wear resistance, it is especially suitable to manufacture parts under wear condition.

金属陶瓷硬质覆层材料是一种具有高耐磨损性能的新型层状复合材料，尤其适应于耐磨损零件的制造。

Results showed that the main wear mechanism of automotive engine Oil -pump chain was fatigue wear , and its failure mechanism was the initiation , propagation of cracks and flaking on top layer of pin and bush .

结果表明，汽车发动机机油泵链的主要磨损形式为疲劳磨损，销轴？套筒零件表面的裂纹生成？扩展与剥落是其主要磨损失效机制。

At present, we have six series of products, including all kinds of auto powder metallurgy parts, gas engine, engineering machine, transmission, drive, home-use electric, etc. We also specialize in all kinds of chalybeate powder metallurgic gear and abnormal machine parts, have more than 560 kinds of products.

目前已具备了各种粉末冶金配件的生产能力，形成了包括汽车摩托车、内燃机、工程机械、传动、动力和家用电器等六大产品配套系列，专业生产各种铁基粉末冶金齿轮及异形机械零件560余种。

In assembly drawings, certain technical structures, such as round, chamfer, and undercut can be omitted.

对零件的工艺结构，如小圆角、倒角、退刀槽等可省略不画。

So to become a complete champ it is necessary to enhance your knowledge about different mountain bike parts.

因此，要成为一个完整的冠军，有必要提高自己的知识对不同山地自行车零件。

The changeability of part model is the prerequisite of the changeability of the product model.

零件模型变动性是变量化装配设计中装配模型变动性的前提条件。

Micro-computer processor to ensure the setting of the bag length without changing any parts, preset counter, bag length, packing speed indicator are the part of the function.

微电脑袋长控制器，可任意设置袋长而无需更换零件，并可预制计数，显示包装速度，袋长等。

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。
