零件图

The method is :there are two perpendicular axes whose distance are controlled ,one is the axis of work table, the other is fixed with a microscope for aiming.

该测量方法是：两个相互垂直且间距可调的数控回转轴，一轴与工件的回转中心重合，另一轴上固定可移动的瞄准显微镜，当显微镜瞄准被测孔时，两轴的转角由各自的圆光栅测出，两轴之间的角度位置确定曲面壳体零件上小孔的孔位置，同时采用CCD摄像头，利用图象处理技术实现小孔的尺寸测量。

Under the stochastic demand, one of the key problems for RMS design is how to design the capacity scalability and storage volume. Based on queuing theory, stochastic market demand model for single product family and production model of manufacturing systems were built. The queuing model and the state probability transition graph of RMS were given.

基于排队论方法，建立了单零件族随机市场需求模型与可重构制造系统的排队模型，给出了RMS的排队模型与状态瞬时强度转移图，建立了平稳条件下系统的概率平衡方程，得到了RMS与柔性制造系统的性能指标。

可以用PROE进行较复杂三维零件的绘制，自己用PROE绘制了公司主打产品摆线减速机等的三维装配图，以及爆炸图。

The paper focuses on the technique of machinable features recognition of sheet metal parts in CNC bending process.

可将三维CAD模型映射表示为由特征节点构成的网络图，这一方法可以对钣金零件的折弯加工工序模拟、折弯模具以及折弯夹具进行有效分析

The issues of drawing and dimensioning for the fillet on the parts are researched and discussed,and some suggestions for improvement are also proposed.

本文对零件上圆角在图中的画法和标注进行了研究和讨论，并提出了改进建议。

Reading and dimensioning of the complicated assembly-drawings are explained in course of 3D solid modeling by giving examples.

在三维造型过程中阐述复杂零件的读图和尺寸标注方法，并通过实例进行说明。

Finally, the finite element analysis for the IT shaft of the driving system is fulfilled by using ANSYS 8.0 and the stresses and deformations curves of the Π shaft are obtained. The paper else gives a study on few underprops and a reasonable project about few underprops is obtained.

最后利用有限元分析软件ANSYS 8.0完成传动箱Ⅱ轴零部件静态有限元应力和应变分析，得到Ⅱ轴零件在受载情况下的应力应变图，并对各种支撑情况进行了研究，提出合理的径向轴承布置方案。

In view of the development about the certain airborne radar antenna array,considering the structural features of antenna array,analyse the cruces in manufacturing of feed cavity and radiant plate,and present the corresponding solution by mainly dealing with precise positioning style,delicate clamp design,error distribution and compensation method,high speed machining technology design,machining simulation and program optimizing.

某机载雷达平面裂缝阵列天线的单面阵如图1所示。该面阵布置多路裂缝线源，共分布384处长度各不相同的辐射裂缝，每一路线源均由脊型波导口单独馈电。面阵由辐射板和馈电腔两个零件组成，采用整体钎焊成形。线源结构为非对称单脊共线形式，即在普通单脊波导的两侧与辐射裂缝相对应的位置上布置不对称的凹台。

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。
