Each sample value is represented by a 3-bit code word corresponding to the amplitude zone into which the sample falls.

每个采样值都可以用一个与采样所规定的幅值区域相对应的3位编码字来表示。

Thus,when a DAC converts the code words to form the original analog waveform ,it is possible to reconstruct only an approximation to the original signal- the reconstructed voltage is in the middle of each zone .

Most laminated materials are cold rolled and often specially annealed to orient the grain or iron crystals.

大多数叠片材料需要经过冷轧加工，而且经过特殊的退火处理后可使晶体获得各向异性。

A large reduction in leakage flux can be obtained by further subdividing and sandwiching the primary and secondary turns,however,at considerable cost.

进一步细分绕组并增加原边和副边的匝数可以大大降低漏磁通，但成本却提高很多。The coils employed in shell-form transformers are usually of a pancake form unlike the cylindrical forms used in the core-form transformer,where the coils are placed one on top of the other and the low-voltage winding is placed closer to the core with the high-voltage winding on top.

芯式变压器的线圈采用圆柱结构，与之不同的是，壳式变压器的线圈通常采用饼形结构。芯式变压器中一个线圈位于另一个之上，并且高压线圈在上，低压线圈更靠近铁芯。

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。

《电气工程及其自动化专业英语》考查

《电气工程及其自动化专业英语》考查试卷 学院：专业：班级：姓名：学号： 翻译：(5×20＝100) 1. In order to reduce over voltages due to line energizing or reclosing, resistors are almost always preinserted in circuit breakers at 345 kV and above. Resistors ranging from 200 to 800 Ω are preinserted when EHV circuit breakers are closed, and subsequently bypassed. When a circuit breaker closes, the source voltage divides across the preinserted resistors and the line, thereby reducing the initial line voltage. When the resistors are shorted out, a new transient is initiated, but the maximum line voltage can be substantially reduced by careful design. 2. To protect equipment such as a transformer against overvoltages higher than its BIL, a protective device, such as that shown in Figure 19.7, is employed. Such protect devices are generally connected in parallel with the equipment from each phase to ground. As shown in Figure 19.5, the function of the protective device is to maintain its voltage at a ceiling voltage below the BIL of the equipment it protects. The difference between the equipment for voltage and the protective device ceiling voltage is the protection margin.

The nature of the model and the methods employed in obtaining it are dependent on the depth of understanding needed at a particular stage of the design study,and on the use to which the model will be put. 这些要求利用数学建模技术设计的重要组成部分大自然的模型和方法的使用,在获得它依赖于需要理解的深度在某一阶段的设计研究,模型的使用将。 It is desirable first to define what is meant by a system,a word which is frequently used in conversation .Broadly,a system can be thought of as a collection of interacting components , although sometimes interest might lie just in one single component. These components will often be functional parts of such physical components. The system of interest might be a power station , a steam turbine in the power station,or a control valve on the turbine;it might be an aeroplane,its air conditioning,an engine,or part of an engine;a process plant for the production of a chemical , or a large or small part of the plant;a human being,or some part of the body such as the muscle control mechanism for a limb;or it might be economic system of country,or any other from a wide range of fields. 首先,这是合乎情理的定义指的是什么系统,一个词经常被使用在谈话.Broadly,一个系统可以被认为是相互作用的部分组成的集合,尽管有时利益或许生存期就一个单一成分这些组件功能部位常常会这样的物理单元系统的兴趣的可能是一个电站、蒸汽涡轮机在电站、或控制阀门靠涡轮,还可能是飞机,它的空调、发动机,或部分引擎;工艺厂生产一种化学,或大或小的部分厂;一个人,或某些部位如肌肉控制机制,一根大树枝或者它可能是经济制度的国家,或任何其他从广泛的领域。 The system would normally be considered conceptually as being that part of the universe in which interest lay.There would be interaction between the system and certain parts of the surroundings known as the environment.The two would be separated by an imaginary boundary.In defining the system and its environment it is necessary to decide where this boundary should be placed;this decision depends both on the physical entities involved and on the purpose of the investigation. 系统将概念上通常被考虑作为是兴趣位置宇宙的那个部分。有周围之间的系统和某些部分的互作用以环境著名。二将由一个虚构的界限分离。在定义系统和它的环境决定是必要的哪里应该安置这个界限; 这个决定取决于介入的物理个体和调查的目的。 In studying a power station,interest might lie primarily in the relationship between the power station and the community,in which case the system and its environment might be envisaged as in Fig.5-1.There might,however,be a more specific interest in the speed control system of the turbogenerator,in which case the system could be as in Fig.5-2. 在研究一个发电站，可能主要在于利益之间的发电站和社区，在这种情况下，系统及其环境可能设想在图5 - 1的关系。有可能，不过，是在汽轮发电机组调速系统，在这种情况下，该系统可以在图5 - 2更具体的利益。 In abstracting from the whole the system of interest,it is necessary to consider carefully where
