几个复杂的翻译例句 1．The history of the Internet dates to the early days of computer networking in the 1960s. Today, when many workgroups have personal computers linked together in Local Area Networks (LANs), it's somewhat difficult to envision a world when mainframes dominated, and getting those mainframes to talk to one another was a bold new concept.
因特网的历史可以追溯到计算机开始联网的六十年代。今天，当很多工作小组都已拥有
自己在局域网中互相联网的个人计算机时，人们也许很难想象，在大型计算机机独霸天下的年代要想让这些大型机互相进行信息交流曾被认为是一种十分大胆而超前的设想。
2．The use of programming languages (compilers) not only results in higher part
quality but also allows for more rapid development of machining instructions. In addition, simulations can be run on remote computer terminals, to ensure that the program functions as intended. This method prevents unnecessary occupation of expensive machinery for debugging procedures.
采用编程语言（编译程序）不仅能提高零件加工质量而且还可更快地开发出加工指令。
此外，我们还可在远处的计算机终端进行加工模拟以确保该程序能按我们意图正常操作。采用这种方法这就避免了在调试程序时不必要地占用昂贵的机床设备。
3．Performance demanded of machining center spindles by modern
high-performance cutting tool materials include stiffness. running accuracy (run-out), axial load-carrying capacity, thermal stability, and axial freedom for thermal expansion.
现代高性能刀具材料对加工中心的主轴提出的特殊性能要求包括刚性、运动精度、轴向
承载能力、热稳定性以及轴向热膨胀自由度等。
demand sth. of (from) sb. 向某人提出要求某物，该句用过去分词短语demanded of….修饰Performance,类似句子还可用名词形式的demand 构成。e.g. I have a demand to make of him. 我对他有一个要求。
4．A manufacturing system can be defined as a series of value-adding
manufacturing processes converting the raw materials into more useful forms and eventually finished products.
一个制造系统可以定义为一系列将原材料转变成更有用的形式，直至最终产品的增值的
制造加工过程。value-adding 增值的，有附加值的
5．Lead times are of two types: a) ordering lead time and b) manufacturing lead time.
Ordering lead time is the total amount of time between initiating a purchase order
and receiving the goods. Manufacturing lead time is the total amount of time required to perform all the preparative steps necessary to produce a given part.
我们常说的lead time 有两种：一是交货期（从订货到交货的时间），另一个是指制造（生产）准备周期。前者指从发出购货订单到接收货物之间的总的时间；后者包括完成生产某个零件（或产品）所需的一切准备步骤所花费的全部时间。
7．Whether an expert system in fact replicates the reasoning process used by a
human expert is primarily of interest to computer scientists, as a practical matter it is only necessary that the expert system replicate the results the human expert would have obtained under the same circumstances.
究竟一个专家系统事实上是否在重复一位人类专家所采用的推理过程，这对于计算机专
家来说有着十分重要的价值。因为事实上我们就是要求专家系统能够完全重复在同样条件下人类专家所能获得的同样结果。
be of interest to 对…..来说值得注意，有重大意义。….that expert system replicate
这里的动词replicate 用原形是虚拟语气句式所要求的，因为前面有it is necessary….. 。
8．But marketplace change is only one dimension of the competitive pressures that
companies and people are experiencing today. At a deeper level, we are changing from a competitive environment in which mass-market products and services were standardized, long-lived, information-poor and exchanged in one-time transactions to an environment in which companies compete globally with niche market products and services that are individualized and customized,short-lived, information-rich, and exchanged on an ongoing basis with customers.
但是，市场的变化只是商家和生意人当今所面临的竞争压力的一个方面。从更深层次来
分析，我们正从一个市场寿命较长的，信息含量较少的并且是一次性完成交易的具有大量市场的标准化产品或服务的竞争环境逐步转变为另外一种新的市场竞争环境。在这种新环境下，各公司利用各自最有优势的热门产品和服务在全球范围内展开竞争。而这些产品和服务的特征是具有个性化、定制化，市场寿命短，信息含量高而且与客户的交易是建立在一个不断发展和扩大的贸易基础之上的。
9．In automobile manufacturing, for example, we can use alternative fuels for
internal combustion energy: liquid petroleum gas (LPG), natural gas (NG), alcohol and hydrogen; or we can design alternative vehicles: electric and hybrid vehicles, fuel cell vehicles 例如在汽车制造中，（为节约能源）我们可采用一些替代燃料来作为汽车发动
机的能源：如液化石油气、天然气、酒精和氢气等；也可设计其他替代交通工具如电动汽车、混合动力汽车以及燃料电池汽车等。
10．A considerable overlap is emerging in the manufacturing methods employed in
very different areas such as mechanical engineering, optics and electronics, and so appeared a new term recently in manufacturing- “optical, mechanical and electronic integration”.
以往在机械工程，光学，电子学等完全不同的领域所采用的制造方法正越来越呈现出相
互交叉与重合，因而目前在制造界出现了一个新名词－光、机、电一体化。
11． It is relevant to the applications that will be discussed that individual atoms are
easily resolved by the STM, that the stylus tip may be as small as a single atom and that the tip can be positioned with sub-atomic dimensional accuracy with the aid of a piezoelectric transducer.
这个句子结构比较复杂，含有四个”that”，第一个that 是定语从句的先行词，代表前面
的applications；第二、三、四个that 是三个并列的主语从句的关联词，这个that引起
的从句是实际主语。该句的译文是：以后将会讨论到，它同以下几个应用实例相关：第一，单个的原子容易用扫描隧道显微技术（STM）分辨开来；第二，触针针尖本身可以小到原子级；而第三，触针针尖的定位精度则可达到亚原子级。
