In case of the usage as assembled parts control of the dimensions of molded parts will be the goal of quality management.

在用法的情况下作为维度的装配的零件控制被铸造的零件将是质量管理的目标。

According to monotone assembly sequence planning, a decomposition process is developed to generate the assembly sequences. We infer the disassembly direction set of part by use of sphere projection and Cobstacle etc.

在建立的装配模型基础上，先通过对装配模型中零件间的装配关系做矢量分析，应用球面投影处理、投影法和C-空间障碍可以得到各零件在产品中的拆卸方向域信息。

Monte Carlo method is the most popular all of these methods, but its efficiency is low.

在机械零件的疲劳强度计算过程中，也常常需要预测零件的疲

Although Cisco says the quality of the workmanship is up to snuff , it has to fly parts in because the ports are so slow—and getting them to the factory right when they're needed is proving nettlesome.

即使思科说这个制品的品质状况良好，它仍需空运零件进来，因为港口实在太慢了-而且当需要时把零件直接运到工厂证明结果是令人生气的。

The paper introduces that under special technology condition, Nona material infiltrates through matrixes of machinery parts to refine crystal grains, increase matrix tenacity , strength and hardness, reduce friction factors and high performance and long lifetime machinery parts are manufactured.

本文介绍在特定的工艺条件下，将纳米材料渗入到机械零件的基体中，使基体材料晶粒细化，韧性增加，强度增加，硬度增加，磨擦因数降低，从而制造出了高性能长寿命的机械零件。

Using the changing rate of maximum feed-rate as a threshold,the surface of the part is divided into different areas according to the values of normal curvature radius.Then the feed-rate is adjusted by constant velocities of cutter contact,thus the adaptive variation of feed-rate can be reached.An example is given to prove the ra...

以最大工作进给速度的变化比率为阈值，把零件表面的法曲率半径划分为不同的区域；在不同的曲率区域内，分别以恒定的刀触点速度对进给速度进行修正，修正后的进给速度随着零件表面曲率的变化而自适应变化；实例表明该方法具有合理性和有效性。

This is a 4 axis unit with a mechanical follower to maintain the probe normal to the surface as it scan over the complex surface.

该4轴系统带一个机械跟随装置，能够保证在探头扫过复杂零件表面时探头与零件表面保持一定的距离。

After the design with studying to the automatic graduation numerical control backward table of his major hardware device is carried out, the range of processing complex ruled surface by WEDM is widened, and the problem in cutting parts with complex surfaces is solved.

开发了能实现空间曲面零件电火花线切割加工的极坐标加工系统，阐明了系统的组成和运动规律，对其主要硬件装置———翻转式自动分度数控回转台进行了设计和研究，从而进一步拓宽了电火花线切割加工的工艺范围，解决了空间曲面零件的加工难题。

ABSTRACT: This design elaborated the patch cord plank outer covering plastic parts injection mold design process, including the cavity quantity and deciding the arrangement of the cavity, selecting the machine for injection, the feed system design, choosing the molding boards and their standardized parts, design core-pulling outfit and formed accessories and so on, the basically design flow and the process of injection-mold design based on Pro/E was illustrated.

摘 要：本次设计阐述了插线板外壳塑料零件的注射模设计过程，包括型腔数量和布局的确定、注射机选择、浇注系统设计、模板及标准件的选用、脱模及抽芯机构的设计、成型零件的设计等，阐述了采用Pro/E进行注塑模具设计的基本流程以及模具各部分结构的设计过程。

This process can reduce the consumption of expensive photosensitive resin and the processing time.

随着光固化技术的发展，其设备能够加工的零件尺寸越来越大，相应的增加了零件加工的原材料消耗和机器加工时间。

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。
