零件

Many people mistakingly interpret the word failure to mean the actual breakage of a part.

很多人错误的把一个零件发生故障或者失效理解成这样就意味着一个零件遭到了实际的物理破损。

With the development of manufacturing technology, the noncircular turning process has emerged as a successful alternative to the manufacturing operations mentioned above.

非圆零件车削加工由于成本低、效率高等特点，已逐渐成为一种非常具有竞争力的非圆零件加工方法。

Based on the feature construction technology, the authors presents the ideals and methods of conceptual parametrical model from 3D-design point of view. Using shaft as a demonstration, the authors analyze and discuss the definition and classification of features, common technology of constructing models, and the result of this method.

安军从机械零件三维设计的角度出发，利用特征造型的技术，提出了构造概念化参数模型的思想和方法，以轴类零件为例，分析和探讨了特征的分类、定义及模型建立的一般技术，并给出了应用该方法进行设计的结果。

Today, the products are manufactured according to ergonomics and artistic. So, engineers usually design an object with exquisite shapes. Before the products are manufactured, they will be segment to several parts with machinability. Those parts usually have the feature of free-form surface. However, it is difficult to determine whether those parts are partible or not.

现今的产品，为了人体工学、视觉美观的因素，常设计了相当精巧的曲线，所以切割出来的零件常具有复杂曲面的特徵，这些复杂曲面通常造成了判断零件的可脱模性上，相当大的困扰，在模具设计的流程中将会增加相当多的时间。

If an overall pattern appears on the test surfaces, how should the inspector reprocess the test piece?

如果零件上出现遍及表面的显示，检验员应如何重新处理零件？

They are used to reinforce resina and metals to provide structural materials with high strength and stiffness and light weight.

所制成的复合材料可以用来制作直升飞机的电机叶片、喷气发动机的压缩机叶片、高尔夫球杆、自行车零件、滑雪板以及机器零件。

In the research of molding performance of MIM feedstock, for the shortcoming of capillary rheometry, it was propounded that using spiral mold test molding performance of feedstock, and a set of spiral mold was creatively designed with quickly exchange gates and closed mold cavity.

不锈钢模芯零件充模仿真分析表明，由于熔体流动的&跑道效应&，采用单浇口注射成形两侧流动严重不平衡，端面四个波峰和波谷明显，中部芯柱出现欠注，并发现该零件中间芯轴处成形最困难。

In the calculation and design module, the design of every component part can be carried out by a parameter driving conception mode, i.e. obtaining concrete mode by seriate dimensions driving. In NC programming, based part feature three cutting forms can be selected.

在设计计算中，各零件的设计采用参数驱动的概念模式，由系列化的尺寸参数驱动产生具体模型；在数控编程中，根据零件的特征，系统提供了三种粗切削的方式。

The feasibility of a spheric polishing by FRP-1 flexible polishing machine is proved by experiments.

为了研究FRP-1型非球面柔性抛光机加工非球面零件的可行性，利用FRP-1型非球面柔性抛光机对非球面光学零件进行抛光实验。

We need to see a picture of broken parts or a sprew that has missing parts in the unwrapped plastic bags when you ask for a replacement.

当你申请调换的时候，我们需要看破损零件或者是在未开封的塑胶袋中缺少零件的流道的照片。

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。
