科技英语课文翻译及课后答案
第一单元自动化第二部分阅读A自动化的含义“自动化”已经是，而且现在仍然是，一个被大量滥用的词。
但是，人们对其确切的意义以及所包括的内容，正在逐渐地有了较为正确的了解。
如果不是下一个定义的话，我也许可以尝试作些解释，把自动化说成是一个概念。
运用这个概念，人们通过对机器装置的性能进行充分的测量、观察和控制，从而使其以最高的效率运转。
这需要对这种装置的功能有一个详细而连贯性的了解，以便需要时便能运用最佳的矫正操作。
自动化按其确切的意义，只有全面运用通信、计算和控制三个主要组成部分（“三C" )才能完全实现。
我认为，确保人们对合为一体的三个组成部分对我们的社会所蕴含着的某些意义有所认识和了解，是很有必要的。
首先，我们不妨考虑工业部门之一的炼钢工业。
在炼钢工业中，自动化已经开始成型。
到过钢厂的人都会知道从高炉开始的各种工艺流程的一些情况，成品条钢或板钢生产出来之后，再准备送往制造工艺车间或汽车厂，这些工艺流程是相互链接的。
为了使工厂中各个车间充分发挥效率，可以使用计算机来控制每个车间。
在此之前，计算机工作所需要的一切资料均输入机内。
就高炉来说，需要给计算机提供装人高炉的原料的信息、高炉工作温度的信息和处理各种各样配料的最好方法等方面的资料。
钢厂的高炉操作是一项复杂而要求技术熟练的作业，需要大量的知识和大量的综合信息，并迅速地做出判定选择，以便确保高炉工艺流程中的下一阶段的有效工作。
计算机对所有这一切都了解得很透彻，能够做出非常大量的中间判定，并且能够把全部信息立刻和不间断地提供给管理人员，以使他们做出高效管理这个工厂所需要的最后决定。
由此产生的信息数据和判定要进行处理，然后转送到下一个工序。
在这里，对操作的一些专门细节再次进行整理，提出最佳和最终的判定，然后对这些信息再一次进行处理并输送给下一道工序。
同时，当信息数据从生产单元的一道工序输送到下一工序并完全结合成为一项新的操作时，每次变化的结果反馈到最初阶段，而且，不断地做进一步的调整，结果是整个工厂的工艺流程便能够高效率地进行下去。
