2、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。 2The use of programming languages (compilers) not only results in higher part quality but also allows for more rapid development of machining

3、 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

4、。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。 3Performance 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

5、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。 4A manufacturing system can be defined as a series of value-adding manufacturing processes converting the raw materials into more
