（1）将下列短文翻译为中文。Noise is probably the only topic in electronics and telecommunication with which everyone must be familiar, no matter what his or her specialization. It is ever present, and limits the performance of virtually every system. Also, the measurement of it is very contentious, with almost everybody having a different pet method of quantifying it and its effects.

（2）将下列短文翻译为中文。Although the direct current is useful, it has one great disadvantage, that is, there is no easy, economical way to increase or decrease its voltage. The alternating current has not this disadvantage. Using a special device, it is possible to transform a high voltage into a low voltage or a low voltage into a high voltage. The device that we use to transform the voltage is called a transformer. The alternating current can also be changed easily into the direct current. The device which can do this is spoken of as a rectifier.

（1）将下列短文翻译为中文。（共20分，每题10分）1. There are two kinds of current: direct current (DC) and alternating current (AC). A direct current is a current flowing in a conductor always in one direction. An alternating current is a current periodically changing its direction of flow. The electric current transmitted through electric power lines is alternating current. This is because AC is easy to control and more economical when we transmit it over long distances.2. By an electric circuit or network we mean a collection of electrical devices (for example, voltage and current sources, resistors, inductors, capacitors, transformers, amplifiers, and transistors) that are interconnected in some manner. The various uses of such circuits, though important, is not the major concern of this text. Instead, our prime interest will be with the process of determining the behavior of a given circuit—- which is referred to as analysis.

（5）The coil to which the voltage is applied is known as the primary, while the one from which the induced voltage is obtained is known as the secondary. If the secondary has more turns than the primary, the transformer is called a step-up transformer in which the AC voltage of the secondary winding is higher than that applied to the primary winding If the secondary has fewer turns than the primary, the transformer is called a step-down transformer in which the AC voltage of the secondary winding is lower than that applied to the primary winding. In a well-built transformer the product of the secondary voltage multiplied by the secondary current is almost equal to the product of the primary voltage times the primary current.
