(total of 30 points)将以下段落翻译成中文。(共30分) 1、Automation can be defined as the technology by which a process or procedure is accomplished without human assistance. It is implemented using a program of instructions combined with a control system that executes the instructions. To automate a process, power is required, both to drive the process itself and to operate the program and control system. Although automation can be applied in a wide variety of areas, it is most closely associated with the manufacturing industries. (10 points) 自动化可以被定义为在没有人工协助的情况下完成一个过程或程序的技术。它是通过一个指令程序和执行一个指令的控制系统来实现的。为了使过程自动化,需要电力来驱动过程本身并运行程序和控制系统。虽然自动化可以应用于各个领域,但它与制 造业密切相关。(10分) 2、An industrial robot is a general-purpose, programmable possessing certain anthropomorphic characteristics. The most obvious anthropomorphic characteristics of an industrial robot is its mechanical arm, which is used to perform various industrial tasks. Other human-like characteristics are the robot's capabilities to respond to sensory inputs, communicate with other machines,and make decisions. These capabilities permit robots to perform a variety of useful tasks. The development of robotics technology followed the development of numerical control, and the two technologies are quite similar. (10 points) 工业机器人是一个通用的,可编程的,具有一定的拟人化特征的机器人。工业机器人最明显的拟人化特征是其机械手臂,用于执行各种工业任务。其他类似于人类的特征是机器人对感官输入作出反应的能力,与其他机器通信并作出决定。这些功能允许机器人执行各种有用的任务。随着数字控制的发展,机器人技术的发展也随之发展起来,这两种技术是非常相似的。(10分) 3、Automated manufacturing systems operate in the factory on the physical product. They perform operations such as processing, assembly, inspection, and material handling. in some cases accomplishing more than one of these operations in the same system. They are called automated because they perform their operations with a reduced level of human participation compared with the corresponding manual process. In some highly automated systems. there is virtually no human participation. (10 points) 自动化制造系统在工厂的实物产品上运行。他们执行诸如加工,组装,检验和物料处理等操作。在某些情况下,在同一个系统中完成多个操作。它们被称为自动化,因为与相应的手动过程相比,它们执行操作的过程,一般让人员参与程度较低。在一些高度自动化的系统中。几乎没有人参与。 IV、Translate the following paragraphs into English. (10 points) 把下列段落译成英文。(10分) 计算机不能直接执行应用程序指令。计算机仅能理解用0和1序列编写的二进制语言。因此实际上,用户的程序只能指定计算机执行何种操作,而不能指指导它如何操作。因此,计算机需要能确切告诉硬件如何去执行所的操作指令。 The computer can not directly execute application instructions. Computers can only understand binary languages written in 0 and 1 sequences. So in fact, the user's program can only specify the computer to perform what kind of operation, but can not guide the how it operates. Therefore, the computer needs to be able to tell the hardware exactly how to perform the required operating instructions. V 、 Writing . (10 points) 写作,10分 Directions: You want to apply for the following post/position: Fashion designer required for your work.
