9、数不清的mass-produced大(批)量生产的,Section II Text,Processes of mechanization have been developing and becoming more complex ever since the beginning of the Industrial Revolution at the end of the 18th century.（自从18世纪末工业革命开始，工业机械化进程一直在不断地发展，并且变得越来越复杂。） The current developments of automatic processes are, how

10、ever, different from the old ones.（但目前的工业自动化过程较以前的工业自动化过程有很大的不同）,Topic,Above,Next,汉,End,The “automation” of the 20th century is distinct from the mechanization of the 18th and 19th centuries in as much as mechanization was applied to individual operations, whereas “automation” is concerned with the

11、operation and control of a complete producing unit.（ 20世纪的工业自动化之所以有别于18、19世纪的机械化，是因为机械化仅应用于操纵(执行）机构，而自动化则涉及整个生产单元的执行和控制两个（核心）部分。 ）,And in many, though not all, instances the element of control is so great that mechanization displaces muscle, “automation” displaces brain as well.（尽管不是所有的情况，但在大多数情况下，控

12、制元件依然发挥着强大的力量，机械化已经代替了手工劳动，而自动化代替了脑力劳动。）,The distinction between the mechanization of the past and what is happening now is, however, not a sharp one. At one extreme we have the electronic computer with its quite remarkable capacity for discrimination and control, while at the other end of the scale

13、 are “transfer machines”, as they are now called, which may be as simple as a convey or belt to another.（机械化程度的发展在过去和现在的区别不是很明显，而在一端是具有强大辨别和控制功能的电子计算机，另一端是我们目前所说的“转换机构”正如传输带一样与其他设备简单地连接起来。 ）,An automatic mechanism is one which has a capacity for self-regulate; that is, it can regulate or control the

14、 system or process without the need for constant human attention or adjustment. （自动调整机构能够自动调节系统，也就是说，它能在没有人干预和调整的情况下，自动对系统或生产过程进行控制和调节。）,Now people often talk about “feedback” as being an essential factor of the new industrial techniques, upon which is based an automatic self-regulating system and b

15、y virtue of which any deviation in the system from desired conditions can be detected, measured , reported and corrected. （现代工业技术的核心因素就是当前人们经常提起的反馈（控制），它是以自动调节系统为基础，借助于系统参考值与期望值之间的偏差来控制，可由自动检测、测量、显示和校正方法得到）,Topic,Above,Next,汉,End,When “feedback” is applied to the process by which a large digital com

16、puter runs at the immense speed through a long series of sums, constantly rejecting the answers until it finds one to fit a complex set of facts that have been put to it, it is perhaps different in degree from what we have previously been accustomed to machines. (反馈控制应用于高速运转的大型数字计算机进行复杂运算时，对于输入的复杂问题

17、，计算机通常会一直运行，直到求出与问题匹配的结果。这或许与我们以前熟知的机器有很大的差别。),But “feedback”, as such, is a familiar mechanical conception. The old-fashioned steam engine was fitted with a centrifugal governor, two balls on levers spinning round and round an upright shaft.(反馈是我们所熟悉的机械概念。旧式的蒸汽机安装有离心式调速器，控制杆上的两个球不停地绕立轴旋转，,If the st

18、eam pressure rose and the engine started to go too fast, the increased speed of the spinning governor caused it to rise up the vertical rod and shut down a valve. This cut off some of the steam and thus the engine brought itself back to its proper speed(气压升高，发动机转速变快，旋转调速器速度增加，使立杆上升，关闭阀门，切断蒸汽，从而发动机恢复

19、到合适的速度。),The mechanization, which was introduced with the Industrial Revolution, because it was limited to individual processes, required the employment of human labor to control each machine as well as to load and unload materials and transfer them from one place to another. (随着工业革命的出现，机械化也随之产生，由于这

20、时的机械化仅局限于单个生产过程。因此，需要使用人工控制每部机器及装卸材料，并把材料从一个地方运到另一个地方。),Only in a few instances were processes automatically linked together and was production organized as a continuous flow.(仅仅在很少的情况下，这些生产过程才能够自动地衔接起来，形成连续的产品生产线。),In general, however, although modern industry has been highly mechanized ever since

21、the 1920s, the mechanized parts have not as a rule been linked together. Electric-light bulbs, bottles and the components of innumerable mass-produced articles are made in mechanized factories in which a degree of automatic control has gradually been building up. (一般而言，从20世纪20年代以来，尽管现代工业已经实现了高度机械化，然

22、而通常机械化的部分还没有联系在一起。机械化的工厂生产了电灯泡、瓶子和大量生产的产品的元件，这些机械化工厂的自动化程度日益得到了加强),Topic,Above,Next,汉,End,The development of the electronic computer in the 1940s suggested that there were a number of other devices less complicated and expensive than the computer which could share the field of mechanical control. (2

23、0世纪40年代电子计算机的发展，意味着在机械控制领域内将出现大量比计算机更简单、更廉价的产品。),These devices mechanical, pneumatic and hydraulic have been considerably developed in recent years and will continue to advance now that the common opinion is favoring the extension of “automation”. (这些装置机械装置、气动装置、液压装置，在近些年内已有了很大的发展，并将继续发展下去，通常认为这有利于自

24、动控制的发展。),Electronic devices, of course, although not the sole cause of what is happening, are nevertheless in a key position. They are gaining in importance and unquestionably hold out exceptional promise for development in the future.(电子设备对目前自动控制的发展仍然处于举足轻重的地位，无疑在今后自动控制发展方面还继续会发挥不可估量的作用。),自从18世纪末工业

25、革命开始，工业机械化进程一直在不断地发展，并且变得越来越复杂。但目前的工业自动化过程较以前的工业自动化过程有很大的不同。20世纪的工业自动化之所以有别于18、19世纪的机械化，是因为机械化仅应用于操纵(执行）机构，而自动化则涉及整个生产单元的执行和控制两个（核心）部分。尽管不是所有的情况，但在大多数情况下，控制元件依然发挥着强大的力量，机械化已经代替了手工劳动，而自动化代替了脑力劳动。 机械化程度的发展在过去和现在的区别不是很明显，而在一端是具有强大辨别和控制功能的电子计算机，另一端是我们目前所说的“转换机构”正如传输带一样与其他设备简单地连接起来。自动调整机构能够自动调节系统，也就是说，它能

26、在没有人干预和调整的情况下，自动对系统或生产过程进行控制和调节。,Topic,Above,Next,英,End,Section II Translation,现代工业技术的核心因素就是当前人们经常提起的反馈（控制），它是以自动调节系统为基础，借助于系统参考值与期望值之间的偏差来控制，可由自动检测、测量、显示和校正方法得到。反馈控制应用于高速运转的大型数字计算机进行复杂运算时，对于输入的复杂问题，计算机通常会一直运行，直到求出与问题匹配的结果。这或许与我们以前熟知的机器有很大的差别。就其本身而论，反馈是我们所熟悉的机械概念。旧式的蒸汽机安装有离心式调速器，控制杆上的两个球不停地绕立轴旋转，气压升

27、高，发动机转速变快，旋转调速器速度增加，使立杆上升，关闭阀门，切断蒸汽，从而发动机恢复到合适的速度。 随着工业革命的出现，机械化也随之产生，由于这时的机械化仅局限于单个生产过程。因此，需要使用人工控制每部机器及装卸材料，并把材料从一个地方运到另一个地方。仅仅在很少的情况下，这些生产过程才能够自动地衔接起来，形成连续的产品生产线。,Topic,Above,Next,英,End,Section II Translation,一般而言，从20世纪20年代以来，尽管现代工业已经实现了高度机械化，然而通常机械化的部分还没有联系在一起。机械化的工厂生产了电灯泡、瓶子和大量生产的产品的元件，这些机械化工厂的
