1.1.1 We consider the flow of electric charges. A unique feature of electric charge or electricity is the fact that it is mobile; that is, it can be transferred from one place to another, where it can be converted to another form of energy.我们认为电荷是流动的。
电荷和电的特点是它具有流动性;即它可以从一个地方转移到另一个地方,在转移的过程中,电荷或电能转变为另一种形式的能量。
1.1.2 The power absorbed or supplied by an element is the product of the voltage across the element and the current through it.一个元件吸收或者发出的功率是元件两端的电压和通过该元件的电流的乘积。
1.2.1 We might observe at this point that the polarity marks on Fig.1-4(b) are redundant since the polarity could be defined by the positions of the longer and shorter lines.大家或许注意到图1-4(b)所标注的极性是多余的。
因为恒压源的极性可以用长线、短线来定义。
1.2.2 It should be noted that an ideal voltage source (dependent or independent) will produce any current required to ensure that the terminal voltage is as stated, whereas an ideal current source will produce the necessary voltage to ensure the stated current flow.应该注意一个理想电压源,(独立和受控)可向电路提供任意电流,以保证其端电压为规定值,而理想电流源,可向电路提供任意电压以保证其规定电流。

Introduction to Automation(自动化简介)Automation is the use of computers and control devices to monitor and control production processes. It has revolutionized various industries by improving efficiency, reducing costs, and enabling automated management of production processes. With the advancement of technology, automation has become an integral part of many industries, including manufacturing, transportation, agriculture, and more.2. Control Systems(控制系统)Control systems are essential components of automation. They manage and regulate the operation of machines and processes, ensuring their efficiency and accuracy. Programmable logic controllers (PLCs) are commonly used in control systems. These digital computers are designed to automate electromechanical processes and provide precise control over various industrial operations.3. Sensors and Actuators(传感器和执行器)Sensors play a crucial role in automation by detecting and responding to physical input from the environment. They collect data on temperature, pressure, position, and other variables, which is then used for control and decision-making purposes. Actuators, on the other hand, convert control signals into physical action or movement. They enablemachines and processes to perform specific tasks based on the input received from sensors.4. Feedback and Control Loops(反馈和控制回路)Feedback is an important concept in automation. It refers to the information about the output of a system that is used to adjust the system's input or operation. By continuously monitoring and analyzing feedback data, control systems can make real-time adjustments to ensure optimal performance. This is achieved through control loops, which consist of sensors, controllers, and actuators working together to maintain desired system conditions.5. Human-Machine Interface(人机界面)The human-machine interface (HMI) is the interface between humans and machines. It allows users to interact with automation systems through a graphical user interface (GUI) or other input devices. HMIs provide real-time data visualization, system status monitoring, and control options, enabling operators to effectively manage and control automated processes.6. SCADA Systems(监控与数据采集系统)SCADA (Supervisory Control and Data Acquisition) systems are used for remote monitoring and control of industrial processes. They collect data from various sensors and devices, analyze it, and provide real-time information to operators. SCADA systems play a crucial role in ensuring the efficient and safe operation of automated processes, as they enable operators to monitor and control multiple systems from a centralized location.7. Robotics(机器人技术)Robotics is a branch of automation that focuses on the design, construction, and use of robots. Robots are programmable machines that can perform tasks autonomously or with minimal human intervention. They are widely used in manufacturing, healthcare, agriculture, and other industries to automate repetitive or dangerous tasks, improve efficiency, and enhance overall productivity.8. Industrial Internet of Things(工业物联网)The Industrial Internet of Things (IIoT) refers to the network of physical devices, vehicles, and other objects embedded with sensors, software, and connectivity. IIoT enables data exchange and automation in an industrial environment. By connecting machines, systems, and processes, IIoT facilitates real-time monitoring, predictive maintenance, and improved decision-making, leading to increased efficiency and productivity in industrial operations.以上是关于自动化专业英语的相关内容,包括自动化概述、自动化专业英语词汇和表达方式。

翻译P.1The voltage across a pure inductor is defined by Faraday’law,which states that the voltage across the inductor is proportional to the rate of change with time of the current through the inductor.thus we have U=Ldi/dt.纯电感电压由法拉第定律定义,法拉第定律指出:电感两头的电压正比于流过电感的电流随时间的变化率。
所以可获取:U=Ldi/dt式中di/dt = 电流变化率,安培/秒;L =感觉系数,享利。
P.3A three-phase electric circuit is energized by three alternating emfs of the same frequency and differing in time phase by 120 electrical degrees .三相电压的产生三相电路可由三个频次同样在时间相位上相差120°电角度的电动势供电。
P.9One problem with electronic devices corresponding to the generalized amplifiers is that the gains,AU or AI ,depend upon internal properties of two-port system( ).This makes design difficult since these parameters usually vary from device to device ,as well as temperature .运算放大器像广义放大器这样的电子器件存在的一个问题就是它们的增益 AU 或 AI 取决于双端口系统 (m、b、RI、Ro 等)的内部特征。
自动化专业英语复习提纲
自动化1021、1022班《自动化专业英语》课程复习提纲考核方式:开卷考试考试范围包括:CHAPTER 1 FUNDAMENTALS OF AUTOMATIC CONTROLCHAPTER 2 MEASURMENT AND ACTUATORSCHAPTER 4 COMPUTER CONTROL SYSTEMS(自学)CHAPTER 5 AUTOMATIC CONTROL SYSTEMS(第五章只考其中的单元5.1 Mathematical Modeling of Physical System)(自学)考试题型:PART1:自动化专业词汇英译汉(每小题1分,共30分)PART2:自动化专业词汇汉译英(每小题1分,共30分)PART3:短文英译汉(每小题10分,共40分)CHAPTER 1和CHAPTER 2是上课讲过的内容,作为重点复习,专业词汇部分的英译汉和汉译英会考到课上讲过的词汇和每个单元后面word and expressions 里的词汇。
CHAPTER 4和CHAPTER 5(5.1)属于自学内容,考试偏重比例较小,专业词汇的英译汉和汉译英只考每个单元后面word and expressions里的词汇。
短文翻译部分是课文中的内容,列出几个重点:单元1.1(第1页最后一段)The control objective for the stirred-tank heater is to keep the exit temperature T at a constant reference value Tr. The reference value is referred to as a set point in control terminology. Next we consider two questions.单元1.3(第23页第一段)An important consequence of feedback control is that it can cause system oscillatory response. If the oscillation has a small amplitude and damps out quickly then the control system performance is generally considered to be satisfactory.单元1.3(第24页中间靠下的地方)Before presenting various stability criteria, we introduce the following definition for unconstrained linear systems. We use the term "unconstrained" to refer to the ideal situation where there are no physical limits on the output variable.单元1.4(第33页第二段)The skills needed for good design entail experience, intuition and esthetic sensibility. They are not easily learned from books. The most you ought to expect from any book on design (include this one) is to learn about some useful tools.单元1.5(第45页第一段)After a control system is installed the controller settings must usually be adjusted until the control system performance is considered to be satisfactory. This activity is referred to as controller tuning or field tuning of the controller. Because controller tuning is usually done by trial and error, it can be quiet tedious and time-consuming.单元2.2(第66页第二段)Continuous level monitoring measures the level of the liquid on an uninterrupted basis. In this case the level of the material will be constantly monitored and hence, the volume can be calculated if the cross-sectional area of the container is known.单元4.1(第142页第二段)The sampler is virtual. On a regular basis, under control of the RTOS, values of the AOT output are extracted from the database and routed through to the D/A converter. The sampler is held open long enough for the conversion to take place.。

Translate the following sentences into Chinese。
(2)Although current and voltage are the two basic variables in an electric circuit,they are not sufficient by themselves。
For practical purposes,we need to know how much power an electric device can handle。
