One of the problems in computer science right now is that the standard design for computing is very unlifelike, because living systems have many relatively simple components, and each component does some simple thing, but collectively, the whole network of components computes very complicated things.

目前，计算机科学中的问题之一就是计算的标准设计非常不像有生命力的，因为有生命的系统拥有很多相对较简单的部件，每个部件做一些简单的事情，但是集合起来，整个部件组成的网络就能计算非常复杂的东西。

The possiblehost objective reason all is very many, but, our country numericalcontrol engine bed function part development backwardness -- varietyfew, unit technical level low, performance quality insufficientlystable, the cost stays at a high level, the delivery insufficientlywas prompt and so on -- not to be able to satisfy the numericalcontrol engine bed main engine product need to develop, had noalternative but to say was most direct, the most main reason, Becauseall numerical controls engine bed all is by each kind of function part(including host 轴头, straight line rolls guide rail, ball bearingguide screw vice-, numerical control tool rest, knife storehousemanipulator, rotary table, numerical control servosystem, surveyfeedback as well as safe protective equipment and so on), the functionpart which on foundation rack and so on the lathe bed, column thecollection attire becomes is the numerical control engine bedimportant component, moreover is the indispensable part.

可能主客观原因都是很多的，但是，我国数控机床功能部件的发展落后──品种少，单元技术水平低，性能质量不够稳定，成本居高不下，交货不够及时等──满足不了数控机床主机产品发展的需要，不能不说是最直接、最主要的原因，因为所有的数控机床都是由各种功能部件（包括主轴头、直线滚动导轨、滚珠丝杠副、数控刀架、刀库机械手、回转工作台、数控伺服系统、测量反馈以及安全防护装置等）在床身、立柱等基础机架上集装而成的，功能部件是数控机床的重要组成部份，而且是不可或缺的部份。

At present, three parts of the core assemblies, including the electric motors, controllers and bodyworks, have been mature both in the theory and the technology, but other two major ones such as storage cells and chargers cannot satisfy the requirement of electric cars.

目前，电动车核心部件中的电动机、控制器和车体三大部件在理论和技术上已较为成熟，而另两大部件蓄电池、充电器的发展还不能满足电动车的要求，有一些理论和技术问题还有待攻关，现已成为影响电动交通工具发展的瓶颈。

Chapter 2, the structure of bilateral symmetrical drive parts having large feeding force is presented, the researches on the relation of feeding quantity with input power, invert efficiency, physical parameters, geometrical parameters, and environmental factors is made, and the response and nonlinear characteristic of the drive parts is analyzed.

第二章，首次提出双边对称驱动的具有大进给力的纳米级热驱动部件结构，研究驱动部件进给量与输入功率、转化效率、物理参数、几何参数，以及环境因素之间的关系，并且分析驱动部件的响应特性和非线性特性。

D models are the most widely spread in the world of turbo-machinery for its simplicity, but they are indeed purely empirical correlations which not only fail to provide detailed information inside one or more components, but also require significant effort to recreate themselves if engine operating conditions or component representations change; quasi 3-D models have been the workhorses for compressor and turbine design for many years, and the primary benefit of using quasi 3-D system models is to facilitate the design and detail analysis of a particular component across the range of possible boundary conditions; Full 3-D models are gradually replacing quasi 3-D ones by virtue of requiring no exit flow angle model and loss model and being capable of predicting secondary flow in cascade.

零维模型由于使用时简单易行，因此在涡轮发动机的仿真中得到广泛应用，但零维模型作为纯粹的经验关系式无法反映部件内部的流动细节，并且一旦部件有少许改动则新特性的建立耗费巨大；准三维模型由于能够详细地提供部件内部的流动情况，方便设计而成为涡轮和压气机设计的主要工具；全三维数学模型正逐步取代准三维模型在涡轮设计中的主导作用，同后者相比前者能够预测叶轮机械内的二次流动，在粘性流计算时不需要气流角和损失的经验公式，因此拥有巨大的发展前景。

The Allowance Parts List, Code Identification Numbers and National Stock Numbers are used by the Navy in the Parts Control Center to order replacement valves or parts of valves that are installed on board United States Navy vessels.

美国海军部件控制中心采用认可部件清单，鉴定编号和美国国家库存编号来订购安装在美国海军船舶上的更换阀门或阀门部件。

To study resistance reduction of subsoiling components and energy consumption and to meet the farming request have become the key items in agricultural machinery area.

论述了深松机具的种类以及深松部件减阻节能的技术措施，分析了土壤-深松部件接触系统的相互关系，提出了基于典型土壤动物的脱附减阻和深松碎土机理的仿生深松部件的设计思路。

Said rotating device comprises two components (1, 2) which can be rotated in relation to each other, one (1) of them being configured as a pivot bearing used to fix the other component (2) at the crossing point.
