第四类是一些专用的缩略词。这些词都有明确的含义， 并已约定俗成。如PC、IC、AC、DC、AM、PM、CMOS、 FM、CAD、BASIC、DOS、TV、PCB等，它们的使用使得 科技文献简洁而又明了。
第五类是由某种构词法组合而成的专用科技词汇，如 transceiver、kilometer、multimedia等。
【例】 The total weight being less, it is possible to build much taller building.
【例】 The demands for sophisticated analysis, coupled with some serious limitation on computational capability, led to a host of special techniques for solving a corresponding set of special problems.

三、词汇 专业英语词汇的词形一般较长，并且为了用词准确， 专业英语一般多用词义专一且稳定的词，尽量避免含糊不 清或一词多义的现象。专业英语词汇大多来源于希腊语和 拉丁语，前后缀出现的频率特别高，不少专业英语词汇多 产生于派生法，如automation、decompose、expectation、 multiplication、telephotograph、ventilate。此外，专业英语 常用意义确切的单个动词代替含义复杂的动词短语，如 absorb——take in，accelerate——speed up，support——hold up，
16
第三类是纯科技性的符号、公式、方程式等。这些专 用符号一般来讲是最易于用做区分专业英语文章与普通英 语文章的标志的，它们一般只用在专业文章中，如U = IR、 di/dt、I等。值得注意的是，这些符号、公式、方程式等尽 管在不同的语言中读起来差异很大，甚至完全不一样，但 从书写形式上看都是一致的，这为读者阅读理解英文原版 文献及从事英文专业写作提供了极大的方便。

⑴过去分词required充当后置定语， 修饰electromotive force；⑵having a resistance of one ohm是现在分词短语， 充当后置定语，修饰conductor。
Chinese Translation of Texts
对电流的阻力叫电阻, 用字母符号R表示。电阻的单位是欧姆，常用Ω表示。1欧 姆的定义是：当加到导体上的电压为1伏特时，将导体中的电流限制为1安培所需的 电阻值。较大的电阻值常用千欧( kΩ )和兆欧（MΩ）表示。
Chinese Translation of Texts
The relationship between volts, amperes, and ohms can be represented by “ Ohm’s Law”. Ohm’s Law states that the ratio of the voltage between the ends of a wire and the current flowing in it is equal to the resistance of the wire. Now, we can say that when a given voltage is applied across the ends of the wire, an electric current always flows along it, and the value of this current depends on the resistance of wire (as shown in fig.2-1).

digital information signal. In the system shown in Figure1.1(b) analog modulation involves the variation of the light emitted from the optical source in a continuous manner. With digital modulation, however, discrete changes in the light intensity are obtained (i.e. on-off pulses). Although often simpler to implement, analog modulation with an optical fiber communication system is less efficient, requiring a far higher signal to noise ratio at the receiver than digital modulation.

Unit1 Basic concepts of circuit theory
Noise is relatively easy to eliminate from digital signals because it is easy to distinguish from the desired signal which can only have particular values. For example: if the signal is meant to be +5V (true) or 0V (false), noise of up to 2.5V can be eliminated by treating all voltages greater than 2.5V as true and all voltages less than 2.5V as false.
Current is measured with an ammeter, connected in series.
To connect in series you must break the circuit and put the ammeter acoss the gap, as shown in the diagram .

Unit1 Basic concepts of circuit theory
Digital systems contain devices such as logic gates, flip-flops, shift registers and counters. A computer is an example of a digital system.
通信工程专业英语TEXT1信息的数字表示
The key advantage of digital representation lies in the universality of representation. Since any medium, be it a text, an image, or a sound, is coded in a unique form which ultimately results in a sequence of bits, all kinds of information can be handled in the same way and by the same type of equipment.Furthermore, transformations of digital information are error free, while analog transformations introduce distortions and noise.1 StorageThe same digital data storage device can be used for all media. The only difference may lie in size requirement.Still images and motion video require larger volumes than text or graphics. Sound also is demanding though less so than imaging. Thus, appropriate digital devices may be required, such as compact disk-read-only memories (CD-ROMS). But the key point is that a single type of digital device may store all kinds of information.2. TransmissionAny data communication system capable of carrying bits has the potential to transmit any multimedia digital information. Thus, a single communication network supporting digital transmission can, in theory, be envisaged.This concept is referred to as an integrated services digital network （ISDN), which is a facility aimed at integrating the transport of all information media.The difficulties may arise from the requirements of certain applications, in particular those which need to respect with fidelity（忠实、保真度）the time-dependency of digital signals.Even when the potential for integrating different types of information on a single communication system is not exploited, the benefits of digital versus analog transmission are numerous. First, digital signals are less sensitive to transmission noise than analog signals. Second, the regeneration of the signal--which is the process by which an attenuated signal is strengthened -- is easier. Third, error detection and correction can be implemented. Fourth, the encrypting of the information is also easier.3. ProcessingAs all information is stored on computers, it can be processes, analyzed, modified, altered, or complemented by computer programs like any other data. This is probably where the potential is the highest.•An attempt may be made to recognize semantic contents (speech, handwriting, form, and pattern recognition). An example of advanced contents recognition is the detection of cuts in motion video to automatically identify and index video sequences.•Data structures, chaining using pointers between information elements, may be created for faster and flexible retrieval（检索）.•Powerful editing by cut-and-paste functions to create monomedia (e.g. sound only) or multimedia documents is possible.•The quality of information may be improved by the removal（移除）of noise or errors as shown by the digitization of old vinyl records to create higher-quality audio compact disks.•Information of a similar type but created through different processes---such as motion imaging synthesized by computers and camera-captured video--- may be mixed.•To summarize:•Digital representation permits the storage of different information types on the same device. Information may also be transmitted over a single digital network.Likewise, when digitized, all forms of information may be treated by computer programs, for editing, quality improvement, or recognition of the meaning of the information.4. Drawback (缺点，不足）of Digital Representation of Continuous InformationThe major drawback of the digital representation of information lies in coding distortion. The process of first sampling and then quantizing and coding the sampled values introduces distortions. As a result, the signal generated after digital-to-analog conversion and presented to the end-user has little chance of being completely identical to the original signal.Increasing the sampling rate and multiplying the number of bits used to code samples reduces the distortion. The result is an increased number of bits per time or space unit, called bit rate, necessary to represent the information. There are clearly technological limits to the explosion of bit rates: storage capacity is not infinite, and transmission systems also have limited bandwidths.One of the key issues then is to choose an appropriate balance between the accuracy of the digitization, which determines the bit rate, and the perceived（感知，觉察）distortions by users. Do not forget that it is how distortions are perceived by humans which matters, not what they are physically.Another consequence, as mentioned before, is the need for a large digital storage capacity for moving or still images and, to a lesser extent, for sound. Eight minutes of stereophonic CD sound are enough to completely fill（装满）the 80 megabyte hard disk of a standard personal computer.Fortunately, compression algorithms have been developed to alleviate（缓和，减轻）these requirements. But only spectacular recent progress in digital storage capacity and cost has enabled the development of massive digital storage of media such as images, sound, and motion video.Let us summarize:The digitization process introduces a distortion of the information. Reducing this distortion may be achieved by increasing the sampling rate and the number of bits to code each sample. Images, sound, and motion video require a large amount of digital storage capacity.。
