2、History about electronics
There can be no doubt that the 1900s is remembered as the electronic century. Of course there have been other great advances, in medicine（医学领域）, in transport, in science, in commerce(商业领域), and many other fields but where would they have been without the instruments and devices that electronics has provided?
How would you see a 3D virtual reality image（3D虚拟现实影像） of your beating heart with no electronics? Would you go to a pop concert（流行音乐会）
that had no amplifiers（【电子】放大器，扩音器）, large screens or lighting effects? Don’t say you would rather watch TV-there would not be any.
Electronics in the early 20th century started thriving at a greater speed unlike the pre-20th century developments. The radio（无线电） invented by the Italian genius Marconi and the work of Henry Hertz opened the road to further discoveries and inventions.
In the first decade the new thing that was welcome to the technical world was the vacuum tube（真空管，电子管）. The vacuum tubes at that time worked as a miraculous component for the radio devices.
The invention of the television was a miraculous thing for the mankind. It was revolution in both communication technology（通信技术） and also for the world media. The distances between the continents did not seem to be far enough.
The credit goes to the British engineer John Logic Baird who followed the footprints of Marconi and tried to send the images in the same way as the speech. After a long experiment he found that a series of static pictures, if sent within a small interval of time in between them, seem to be moving.
The real electronics what it is called today was actually started after the discovery of the transistor（晶体管） effect. Transistor opened the road for the computing world. Computers of various types started hitting the market and the research works got a boost.
Some other problems were also there like the assembling（装配，聚集） of the electronic components（电子元器件） on a single mother board（母板，主插件板）. Jack Kilby in Texas Instruments found a very nice solution.
He suggested to throw away all the wires（wire：电线，电报） and tried to connect the resistors（电阻器）, capacitors（电容器） and transistors on the same
piece of wafer（圆片，晶片） internally. Surprisingly his ideas worked and gave birth to the integrated circuit（集成电路） industries.
二、Introduction to some courses

专业知识，可以从事有源模拟滤波器的设计，理解无源网络设计方法，为今后进一步
自学打下良好的基础。
三、knowledge about translation
1、科技英语的特点
1）复杂长句多
科技文章要求叙述正确，用词严谨，因此一句话里常常包含多个分句，这种复杂
且长长的句子居科技英语难点之首，阅读翻译时要按汉语习惯来加以分析，以短代长，化难为易。
Of course there have been other great advances, in medicine, in transport, in science, in commerce, and many other fields but where would they have been without the instruments and devices that electronics has provided?
当然，许多其他行业如医药、交通、科学、商业等也取得很多进步，但如果没有
电子技术所提供的仪器和设备这些行业能取得这么大的进步吗？
2）被动语态多
科技英语为了强调所论述的客观事物，常把它放在句子的首位，以突出其重要性。
Language of C will be used for teaching purposes. Emphasis is towards the use
of programming for engineering applications and problem solving.
为达到教学目的而采用C语言，重点放在如何运用编程技术解决工程应用的实际
问题。
在翻译中可以根据中文的习惯，不一定要译出被动语态。
The following topics are covered.主要包括以下内容。
3）非谓语动词多
英语每个简单句中，只能用一个谓语动词，如果读到几个动作就必须选出主要动
作当谓语，而将其余动作用非谓语动词形式（V-ing, V-ed, to V三种形式），才能符合英语的语法要求。

分词短语作状语时，前面可用when, while, if, unless, though等连词来加强时间、条件等含义。
When measuring current, the circuit must be opened and the meter inserted in series with the circuit or component to be measured.
当测量电流时，必须断开电路，将万用表与待测电路或元器件串联。
与with(without)连用

电气工程及其自动化专业英语 考试题型：选择10*2 单词翻译10*2 短句翻译5*4 长句翻译4*10 Exercise All the simple circuit elements that will be 在下面进行的工作中我们要研究的简单电路元件,可以根据流过元件的电流与元件两端的电压的关系进行分类。例如，如果元件两端的电压正比于流过元件的电流，即u＝ki，我们就把元件称为电阻器。其他的类型的简单电路元件的端电压正比于电流对时间的导数或正比于电流关于时间的积分。还有一些元件的电压完全独立于电流或电流完全独立于电压，这些是独立源。此外，我们还要定义一些特殊类型的电源，这些电源的电压或电流取决于电路中其他的电流或电压，这样的电源将被称为非独立源或受控源。 It must be emphasized that the linear 必须强调的是线性电阻器是一个理想的电路元件；它是物理元件的数学模型。我们可以很容易地买到或制造电阻器，但很快我们发现这种物理元件只有当电流、电压或者功率处于特定范围时其电压——电流之比才是恒定的，并且这个比值也取决于温度以及其它环境因素。我们通常应当把线性电阻器仅仅称为电阻器。只有当需要强调元件性质的时候才使用更长的形式称呼它。而对于任何非线性电阻器我们应当始终这么称呼它，非线性电阻器不应当必然地被视为不需要的元件。 If a circuit has two or more independent 如果一个电路有两个或多个独立源，求出具体变量值（电流或电压）的一种方法是使用节点分析法或网孔分析法。另一种方法是求出每个独立源对变量的作用然后把它们进行叠加。而这种方法被称为叠加法。叠加法原理表明线性电路某个元件两端的电压（或流过元件的电流）等于每个独立源单独作用时该元件两端的电压（或流过元件的电流）的代数和。 The ratio of the phase voltage to the 相电压与相电流之比等于电路的阻抗，符号为字母Z，阻抗是一个具有量纲为欧姆的复数量。阻抗不是一个相量，因此不能通过把它乘以e jωt,并取其实部把它转换成时域形式。但是，我们把电感器看作是通过其电感量L表现为时域形式而通过其阻抗jωL表现为频域形式，电容在时域里为电容量C而在频域里为1/jωc，阻抗是某种程度 上的频域变量而非时域变量。 Both wye and delta source connections 无论是星型连接的电源还是三角形连接的电源都有重要的实际应用意义。星型连接的电源用于长距离电力传输，此时电阻损耗(I2R)将达到最小。这是由于星型连接的线电压是三角形连接的线电压的√3倍，于是,对于相同的功率来说，三角型连接的线电流是星形连接的线电流的√3倍。三角形连接的电源使用在根据三相电源而需要的三个单相电路中。这种从三相到单相的转变用在住宅布线中因为家用照明和设备使用单相电源。三相电源用在需要大功率的工业布线中。在某些应用场合，无论负载是星形连接还是三角形连接并不重要。

英语原文 NUMERICAL CONTROL Numerical control(N/C)is a form of programmable automation in which the processing equipment is controlled by means of numbers, letters, and other symbols, The numbers, letters, and symbols are coded in an appropriate format to define a program of instructions for a particular work part or job. When the job changes, the program of instructions is changed. The capability to change the program is what makes N/C suitable for low-and medium-volume production. It is much easier to write programs than to make major alterations of the processing equipment. There are two basic types of numerically controlled machine tools：point—to—point and continuous—path(also called contouring).Point—to—point machines use unsynchronized motors, with the result that the position of the machining head Can be assured only upon completion of a movement, or while only one motor is running. Machines of this type are principally used for straight—line cuts or for drilling or boring. The N/C system consists of the following components：data input, the tape reader with the control unit, feedback devices, and the metal—cutting machine tool or other type of N/C equipment. Data input, also called “man—to—control link”,may be provided to the machine tool manually, or entirely by automatic means. Manual methods when used as the sole source of input data are restricted to a relatively small number of inputs. Examples of manually operated devices are keyboard dials, pushbuttons, switches, or thumbwheel selectors. These are located on a console near the machine. Dials ale analog devices usually connected to a syn-chro-type resolver or potentiometer. In most cases, pushbuttons, switches, and other similar types of selectors are digital input devices. Manual input requires that the operator set the controls for each operation. It is a slow and tedious process and is seldom justified except in elementary machining applications or in special cases. In practically all cases, information is automatically supplied to the control unit and the machine tool by cards, punched tapes, or by magnetic tape. Eight—channel punched paper tape is the most commonly used form of data input for conventional N/C systems. The coded instructions on the tape consist of sections of punched holes called blocks. Each block represents a machine function, a machining operation, or a combination of the two. The entire N/C program on a tape is made up of an accumulation of these successive data blocks. Programs resulting in long tapes all wound on reels like motion-picture film. Programs on relatively short tapes may be continuously repeated by joining the two ends of the tape to form a loop. Once installed, the tape is used again and again without further handling. In this case, the operator simply loads and
