求翻译一段机械专业文字！！！
We may understand polishing in this article in the machine manufacture profession influential role, the historical development as well as future trend of development. But crank's high accuracy request enables general to spread out rubs very inaccessibility it the accuracy requirement, but polishes this time can demonstrate its superiority. It is well known, polishes in the mechanical profession the utilization is quite widespread, in the market also presented many specialized polishing units, but its use cost is quite expensive. How therefore reduces the polishing cost is the comp book paper main purpose. This article is mainly through to polishes the principle the research as well as to our country now the mechanical profession present situation understanding, we knew that is unoptimistic in western area's mechanical form of enterprise, the equipment gets older, has the massive old style lathes, like C620. Therefore, the design will study a set to be able to use the existing equipment to be able to carry on polishing the polishing simple organization to have the good market value. This paper is precisely embarks from this goal, introduced in detail how to design a set of simple organization use common ordinary C620 lathe to carry on crank's polishing, thus achieves crank's accuracy requirement. In this organization, is mainly and mixes using the crank polished surface has the polishing paste to contact the friction under certain pressure function, causes the crank surface unceasing attrition to be smooth, thus to polishing goal. Must achieve the automatic control pressure card using hydraulic cylinder's function to grasp opens automatically and gathers, the pressure and the crank rotational speed may adjust in the polishing process. this article main in detail introduced how to realize the above request, as well as how finally again on the C620 engine bed the installation and trial run and so on.
多变量网络元件的推广
模型的表示采用了多口元素和多键合涂符号。
在保持了网络模型透明度和特性的情况下，引入多口和非线性元素应对更为复杂的动态行为。
答：为同时提高产量和精度，研究者和设备制造商在传统的铣、钻、车、磨等加工方法外寻求新的方向。随着传统技术的革新，新的切削和制造工艺也随之出现。经过长期的研究，激光辅助制造已走出实验室。它是通过光纤或其他光学传送单元把激光束打到工件上，这个激光装置被安装在刀具前方（如图34.1所示）。切削期间...
答：旋转元素于机械制动,要么是一鼓,一个磁盘,或一系列的磁盘。这nonrotating鼓式制动器摩擦中的元素可以是乐队或一双鞋子(块)的新合约,这鼓的外线或
答：1.螺纹直径范围为6-100毫米，但是螺距在1-60毫米之间，在这两种特性之间保持一种平衡。2.如果螺距大的话，可以获得快速运动，但是机械效益较低。小螺距意味着低速运动，但可获得较高的机械效益；同时，多数推荐采用小螺距以确保驱动系统的精度和可操控性。
答：洞察力和理解力是建立模型的最高目标。我们开发的模型是借助网络元件而建立的系统动力学的状态空间模型。状态空间模型是现代系统控制分析与设计的起点。
答：1 。阿运动链是一个系统的联系，也就是说，僵硬的尸体，要么接合在一起，或在与对方的方式，允许它们将相对彼此。如果其中一个环节是固定和流动的任何其他链接到一个新的立场将导致其他各个环节转移到一定的可预测的立场，该系统是一种约束运动链。如果其中一个环节是举行了固定和流动的任何其他链接到...
答：使用的部件被称为从动件。通过使用凸轮，一个简单的输入运动可以修改成几乎任何可以想象出的理想运动。凸轮普遍应用于以下方面:1 汽车发动机上 2 生产机械工具上 3 自动记数上 4 印刷机上 5 自动洗衣机上 6 自动洗碗机上 7 包括电脑在内的计算设备上 自己翻译的,希望你会满意!
答：1。甲拉丝机组成的多个模具，一个可旋转鼓画线的多元化，通过先后去世，指在一个预定的速度驾驶的鼓点一，可调节位移液压马达连接到另一个鼓驱动同样的，手段提供流体说，在预定的压力电机。2。甲拉丝机组成的多个模具，一个可旋转鼓画线的多元化，通过先后去世，指在一个预定的速度驾驶的鼓点之一，...
答：有两种基本的机械运动：旋转运动和直线运动。旋转运动是围绕一条中心线的圆周运动，直线运动是在直线上的运动。For either rotary or rectilinear motion, it is possible, with added mechanical devices, to produce other forms of motion such as intermittent motion and reciprocating motion.无论圆周...
答：1 INTRODUCTION 1引言 High-efficiency deep grinding (HEDG) offers the possibility to achieve very high material removal rates, while keeping good workpiece surface integ- rity.高效深磨（HEDG）提供了达到很高材料去除率，同时保持工件良好表面完整性的可能。 High wheel speeds (up to 250 m/...
答：也可以是一个中空的，这取决于它是被焊接还是机械线夹来安装到手柄上的。这些都是你们的专业词汇，我用的不是很准确，在这里一一举出，以便你纠正：the carbid tip精磨刀片、the chip breaker断屑器、the pad焊盘、the clamping screw制动螺钉 washer 垫片 nut螺母 shank钻头柄 ...
