机电工程专业英语
单台发电机的容量越来越大，目的就是满足不断增长的用电需求。
(2) What does a fuse do? It protects a circuit. The function of a fuse is to protect a circuit.
A three-phase circuit, as pointed out above, is merely a combination of three single-phase circuits. 正如上面所指出的那样，三相电路只不过是三个单相电路的组合。
3) The transistor, which is working with correctly polarities, can work as an amplifier.

3. 增加表示动词时态的词 汉语中动词没有时态变化，需要在译文中增加时 间副词或助词来表示英语里的不同时态。通常在翻译 现在时，可增添“能”、“可”、“会”等字；译将 来时可增添“将”、“要”、“会”等字；译过去时 可增添“已”、“曾”、“过”、“了”、“以前”、 “当时”、“过去”等词；译完成式可增添“已 （经）”、“曾（经）”、“了”、“过”、“一直” 等词；译进行时可增添“正（在）”、“在”等词。 (1) Scientists are working to develop new ways to make the semiconductor material used in computers and other modern electronic devices. 科学家们正在研 究新的方法制造用于计算机和其他现代电子仪器中的
[1]. Fleming‘s right hand rule. 费莱明右手定则
[2]. Whereas the copper disk will rotate in the same direction as the rotating magnetic field，it will never reach the same speed as the rotating magnet，because if it did，there would be no relative motion between the two and therefore no current induced in the copper disk. 注意本句中的两个时态：“will rotate”表示动作未发生，但存在； “because if it did，there would be no…”使用的是虚拟语态，表示假 设是不成立的。

because they have:
a name: a tag with a unique code;
information storage object called radio frequency identification (RFID). An RFID system consists of three components (as shown in Fig.19-1): an antenna transceiver (often combined into a reader) and a transponder (the tag). The antenna emits radio signals to activate the tag and to read and write data to it. When activated, the tag transmits data back to the antenna. The data transmitted by the tag may provide identification or location information, or specifics about the product tagged, such as price, color, date of purchase, etc. Low-frequency RFID systems (30 kHz to 500 kHz) have short transmission ranges (generally less than six feet). High-frequency RFID systems (850 MHz to 950 MHz and 2.4 GHz to 2.5 GHz) offer longer transmission ranges (more than 90 feet). In general，the higher the frequency, the more expensive the system.

Lesson 22 Artificial Intelligence(AI)
Since World War II, computer scientists have tried to develop techniques that would allow computers to act more like humans. The entire research effort, including decision-making systems, robotic devices, and various approaches to computer speech, is usually called artificial intelligence (AI).

自从第二次世界大战以来，计算机科学家们一直试图开发使计算机能更多地像 人一样行动的技术。所有这些研究，包括决策系统、机器人设备以及各种各样的计 算机语音的实现方法，通常被称为人工智能（AI）。
Chinese Translation of Texts
In many AI programs, facts are arranged to enable the computer to tell how many pieces of information relate to each other and to a given problem. “If／then” rules of reasoning are also programmed in to enable the computer to select, organize, and update its information. According to these rules, if something is true, then certain things must follow. Every action makes new possible actions available.

第一课定期保养定期保养，简单说是一种有组织的维护计划，用于保持设施或设备处于可能的最好状态，以满足生产的需要。
当然，是否处于可能的最好状态是由组织确定的。
当保养计划定出来后，并不是所有的机械都是在同一个时间实施保养的。
有些设备如果缺乏调整，将会损失很多价值或损失设备的灵敏度，因此，必须首先制定一个完善的周密的保养计划。
保养计划涉及四个领域：润滑，检查，清洗，零件调整和修理。
说到保养，首先是有关润滑的问题，包括润滑剂的型号，使用的润滑工具或系统，润滑计划的综合有效性，润滑步骤以及实施润滑的人员。
检查对所有设备的正常维护是至关重要的，正如人们应定期作体格检查一样，印刷机械也应定期检查。
人和工厂都是相似的。
婴儿需要经常检查，年青人和成年人要经常检查，中年人和老年人更需要检查。
与此相同，新机械需要保养，直到设备转入正常工作为止。
在机械开始磨损前给与较少的关注，会导致更频繁的检查。
如下因素有助于制定印刷设备的检查步骤：使用年限，工作条件，设备价值，服务严紧性，安全要求，连续工作时间，设备的损坏敏感程度，设备的磨损敏感程度，对缺乏调整的敏感程度以及操作者个人的工作经验等。
清洗对保养来说是很有必要的，因为它允许人们对适当润滑，磨损因数，合理的调整以及出现故障进行检查。
以重视的态度对印刷设备做恰当操作同样是重要的。
一台清洁干净的机器可给人们能生产出高质量的印刷品的感觉。
确实，如果人们对这些设备高度重视的话，印刷成品将更令人满意。
如果要使可接受的印刷品成为最终成品，零件的调整与修理必须是基本的定期操作。
有些设备要定期更换某些零件，确定零件的有效寿命，然后在磨损之前更换它。
如果事先知道一个零件的寿命，这是一个极为成功的方法，但是，在印刷厂中，只有极少数零件是有一个预期寿命的，这样，检查计划便有助于确定应何时更换零件。
如果机器的调整能确保印刷成品一致的印刷质量，同时降低成本，那么，磨损因数将会降低。
一个定期维护计划只有在印刷质量水平能维持住，并能延长机器的有效寿命时才是有效的。

Text
In general, an electrical machine can be defined as an apparatus that can be used either to convert electrical energy into mechanical energy or to convert mechanical energy into electrical energy. If such a machine is used to convert electrical energy into mechanical energy, it is called a motor; however, if it is used to convert mechanical energy into electrical energy, it is called a generator.
The motion of such a moving part can be linear (e.g., as in linear motors) ; vibrating or reciprocating (e.g., as in various electrical razors ); or rotating.
A generator has a rotary motion provided by a prime mover which supplies mechanical energy input. The relative motion between the conductors and the magnetic field of a generator produces an electrical energy output. On the other hand, a motor has electrical energy supplied to its windings and a magnetic field that generates an electromagnetic interaction to produce mechanical energy or torque[2].
Any given machine can convert energy in either direction and can therefore be used either as a motor or as a generator. Such conversion is ed through the action of a magnetic field [1].

Unit 1 Electrical Machines
Rotating electrical machines have an outside (i.e., stationary) part which is called the stator and an inner (i.e., rotating) part which is called the rotor. As shown in Fig 4.1.1, the rotor is centered within the stator, and the space that is located between the outside of the rotor and the inside of the stator is called the air gap.
In this unit, only the rotating electrical machines will be reviewed. They include (1) polyphase synchronous machines, (2) polyphase induction (also called asynchronous) machines, and (3) DC machines. However, there are other rotating and linear machines that will not be included here. They operate basically on the same principles.
Reading Target 1．Understand the definition of motor and generator. 2．Know the construction and principles of synchronous machines. 3 ． Grasp the classification of electrical machine and what is the difference between the classification of the rotary motor and linear motor.
In general, each machine has a nonmoving (i.e., stationary) part and a moving (i.e., nonstationary) part. Depending on whether such a machine functions as a generator or a motor, the moving part that is attached to a mechanical system receives mechanical input or provides mechanical output.
