The Fig.1.2 shows a simple symmetrical three-phase system. The voltage between phase A and neutral wire is called phase voltage U A; The voltage between phase A and phase B is called line voltage U AB; The current passing through the wire of phase A is called phase current.The load in three-phase circuit has been connected with power supply system in two manners. Such is wye connection and delta connection. If the parameters like impedance and phase of the three-phase load are equality, So they are denominated symmetrical load.The three-phase circuit including symmetrical current power and symmetrical load.Wye connection(Y): the line voltage is 3times as phase voltage, and the phase lead 300.Delta connection(△): the line voltage is equal to the phase voltage, they are in-phase.The three-wire and four-wire circuit, three-phase alternating current power and the load used in the low-voltage distribution system are wye connected. The line voltage is 380V, How to connect the load in the electronic circuit should depend on rated voltage of device. Rated voltage of electric light and electrics is usually 220V, thus it should be taken across between phase wire and neutral wire, and distribute in each phase equably, as shown as the Fig.1.3. Tri-phase symmetrical load electromotor should be connected with the three phase lines. The line near electrical power should build in on-off (like breaker) for switching on or cutting circuit and fusible cutout for short circuit protecting.五、翻译(5*4=20)1、One type of motor starter is the magnetic starter, which relies on electromagnetism to open or close the power source circuit of the motor.Often, motor starters and other control equipment are grouped together for the control of adjacent machines.一类电机起动器是依靠电磁打开或关闭电机电源电路的磁力起动器。

The speed motion in turning is provided by the rotating work-part, and the feed motion is achieved by the cutting tool moving slowly in a direction parallel to the axis of rotation of the work-piece.Drilling is used to create a round hole. It is accomplished by a rotating tool that typically has two cutting edges. The tool is fed in a direction parallel to its axis of rotation into the work-part to form the round hole.In boring, the tool is used to enlarge an already available hole. It is a fine finishing operation used in the final stages of product manufacture.In milling, a rotating tool with multiple cutting edges is moved slowly relative to the material to generate a plane or straight surface. The direction of the feed motion is perpendicular to the tool’s axis of rotation. The speed motion is provided by the rotating milling cutter.Part V Translate Chinese into English (20 %) Directions: This part is to test your ability to do practical writing.1. 这些机器都是由中国人造出的。

In recent years, however, the term machining center has come to be associated almost exclusively with a single machine, usually incorporating automatic tool changing, a rotary table which facilitates circular machining, and one or two integral worktables. Such a machine is usually designed to perform operations on at least four and sometimes five surfaces. There are some machining centers with automatic tool changes in vertical and horizontal configurations. A typical machining center may use 50 or more tools.加工中心的概念是使机床处于工作状态。

( T )2、In a cam mechanism, when the cam turns through one motion cycle, the follower executes a series of event consisting of rises, dwells and returns.在一个凸轮机构中，当凸轮转过一个运动周期时，从动件执行一系列由上升、停留和返回的动作。

( T )3、Integrated circuit is built on a semiconductor substrate, usually one of multi-crystal silicon.集成电路是建立在一个半导体衬底，通常是多晶硅。

( T )4、Krichhoff’s voltage law states that the sum of the potential drops around a loop in a circuit must be zero.Krichhoff电压定律指出，在电路中的回路的电位下降的总和必须为零。

( F )5、Electrons and protons are said to have the same positive charges.电子和质子具有相反的电荷。

( T )6、If a sinusoidally varying voltage source is connected across the capacitor, it can be shown that the voltage across the capacitor lags the current by in phase, meaning that the voltage peaks occur 1/4 of an oscillation period later in time relative to the current peaks.如果一个以正弦波形式随时间正负变化的电压源加在电容上，将会使电容电压在相位上滞后于电流，即该电压的峰值会比电流的峰值晚出现四分之一个周期的时间。
