在工业上应用的黑色金属有两大类：铸铁和钢。

这两类黑色金属通常由生铁炼得，但它们的含碳量不一样。

钢是含碳量为0.0218％至 2.11％的铁碳合金；而铸铁是含碳量超过2.11％的铁碳合金。

工业上不用纯铁，因为它太软。

钢是一种包含铁和碳且添加了其他元素来得到更优性能的合金。

F F1327C256 is a CMOS 256K bit EPROM. The device is organized as 32K words by 16 bits .T T63A disadvantage of connecting lamps in series is that if one lamp blows all of them will go out because the circuit is broken.T T43A lamp may be used to test a rectifier diode, but do not use a lamp to test a signal diode because the large current passed by the lamp will destroy the diode!T T21 A PIC is a Programmable Integrated Circuit microcontroller, a 'computer-on-a-chip'.F F101 A products made of interchangeable parts is slowly assembled, higher in cost.T T68 A relay is an electrically operated switch.T T100 A resistor placed in a circuit will resist the passage of electrical current through it.T T94 A thermistor is an input transducer (sensor) which converts temperature (heat) to resistance. T T99 A transformer consists of two coils (often called 'windings') linked by an iron core.T82A transistor may be used as a switch (either fully on with maximum current, or fully off with no current) and as an amplifier (always partly on).T4 A warning notice has to be set up on the equipment while repairing.F46All rectifier diodes are made from silicon and therefore have a forward voltage drop of 0.2V.T98An audio (AC) signal with a constant DC signal will make a large current flow through the Loudspeaker due to its low resistance, possibly damaging both the speaker and the driving circuit.F105Automatic control systems are a product of this generation.T6Be careful not to damage or scar the inner surface finish of the bottom sub.T133Before logging, inspect the cable drum assembly for apparent damage or cracked welds.T131Before starting engine ,we must check the batteray cables and terminals for corrosion or loose connection. F111Cams are the most versatile lathe.T34Capacitors are also used in filter circuits because capacitors easily pass AC (changing) signals but they block DC (constant) signals.T33Capacitors are used to smooth varying DC supplies by acting as a reservoir of charge.T32Capacitors store electric charge.T8Check the cable and wire for proper connections both before and after repair.F125Checking the engine oil level,we don't wipe dipstick clean ,we can get a good reading.F67Connecting several LEDs in parallel with just one resistor shared between them is generally a good idea.T69Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts.F28Current is measured with an voltmeter, connected in series.T27Current is the rate of flow of charge.T31Currents add up for components connected in parallel.T29Currents are the same through all components connected in series.T57Datasheets are available for most ICs giving detailed information about their ratings and functions. F39Diodes allow electricity to flow in two directions.T77Electrical energy is converted to heat when current flows through a resistor.F14EPROM can be read and writen.F112Form the fits point of view, a key is referred to as the hole and the keyway as the shaft.T44General purpose signal diodes such as the 1N4148 are made from silicon and have a forward voltage drop of 0.7V. T124Going downhole,screw the adjustable uphole torque control valve fully clockwiseF150Heat treatment can decrease material Hardness.T149Heat treatment can increase material Hardness.F103High carbon steel is softer than tempered steel, but it is much more easier to work.T128Hot exhaust system parts can cause serious bodily injury.F114Hot working is defined as plastic deformation below the recrystallization temperature.T121Hydraulic oil temperature is controlled by the thermostatic bypass valve and hydraulic system heat exchanger.T141Hydrostatic charge fluid pressure is measured by the CHARGE PRESSURE GAUGE.T88IC (chip) pin diagrams show the view from above.T54ICs (chips) are easily damaged by heat when soldering ,so we usually use an IC holder(socket).T135If any fuel leaking are found above exhaust system, shut down engine immediately and repair.F118If hoist parking brake control knob is pushed,the brake bands located on each side of the hoist drum tighten and hold the drum.T126If the engine oil level has reached between the high and low mark,the engine oil level is normal.F110If the follower lose contact with the cam, it will natural work.T134If there is no engine oil pressure or low engine oil pressure, stop the engine immediately.T55If you need to remove an IC it can be gently prised out of the holder(socket) with a small flat-blade screwdriver.T85In addition to standard (bipolar junction) transistors, there are field-effect transistors which are usually referred to as FETs.T130Inspect the engine radiator , insure that core is clean and free of debris.T129Inspect the engine radiator cap, verify that the seals and spring are good.T5Install the retaining ring in the bottom sub using the modified pliers.T52Integrated Circuits are complex circuits which have been etched onto tiny chips of semiconductor (silicon). T51Integrated Circuits are usually called ICs or chips.T36It is easy to find the value of electrolytic capacitors because they are clearly printed with their capacitance and voltage rating.T9It is forbidden that using a high-volt insulation tester to measure circuit insulation T113It is important that the product be designed with material.F24It is impossible to have voltage without current, current cannot flow without voltage.F75kF61Lamps can not be connected either way round in a circuit.T59Lamps emit light when an electric current passes through them.T64LEDs means Light Emitting DiodesF65LEDs need not a resistor in series to limit the current to a safe value for testing it.T58Logic ICs process digital signals and there are many devices, including logic gates, flip-flops, shift registers, counters and display drivers.T97Loudspeakers are output transducers which convert an electrical signal to sound. T115Machine parts are maunfactured so they are interchangeable.T102Materials differ widely in physical properties,machinability characteristics,methods of Forming,and possibe service life.T80Multi-way switches have 3 or more conducting positions.T17Normally,the TTL IC use the 5Vdc power supply.T79ON-OFF SPST switch means Single Pole, Single ThrowT15Operational amplifier can be used as a part of an active filter.F96Piezo transducers are output transducers which convert an electrical signal to heat.F87Please note that transistor lead diagrams show the view from top with the leads towards you.T123Pre-start checks,make sure the drum brake is on and both hoist control lever are in the neutral position. T41Rectifier diodes are quite robust and no special precautions are needed for soldering them.T45Rectifier diodes are used in power supplies to convert alternating current (AC) to direct current (DC), a process called rectification.F71Relays and transistors compared ,relays can only switch DC, transistors can switch AC and DC. F127Remove the engine radiator cap when engine is running.T76Resistors in Parallel will get a smaller value.T73Resistors may be connected either way round. They are not damaged by heat when soldering.F72Resistors restrict the flow of electric voltage.T11Rig safety can be improved by using MWD measurements in real time to avoid potentially dangerous well control problems.F62Several lamps can be successfully connected in parallel provided they all have identical voltage and power (or current) ratings.T104Smooth flat belts and V belts depend on friction on the pulleys and some slippage is inherent in their operation.T12Sperry-Sun’s FEWD measurements can be used in horizontal wells to steer a well for maximum formation exposure in the productive part of the reservoir.T56Static sensitive ICs will be supplied in antistatic packaging with a warning label.F78Switch contacts are rated with a maximum voltage and current, and there should be same ratings for AC and DC. F106The all material may have higher strength.T83The amount of current amplification of a transistor is called the current gain, symbol h FE.T47The bridge rectifier have four leads or terminals: the two DC outputs are labelled + and -, the two AC inputs are labelled "～".F22The CMOS circuitry used in the 74HC series ICs means that they are static sensitive. Touching a pin while charged with static electricity is always safe.T66The colour of an LED is determined by the semiconductor material, not by the colouring of the 'package' (the plastic body).F132The drum bearing don't need to be greased separately T109The element must be kept stiff and rigid.T122The engine must be shut down immediately if the water temperature gauge registers higher than normal coolant temperatures.T140The ENGINE STOP CONTROL is used to stop the flow of diesel fuel to the engine.T139The ENGINE THROTTLE CONTROL increases and decreases the speed of the diesel engine.T137The FREQUENCY METER measures the frequency of the diesel generator.T90The heat sink of power transistor helps to dissipate (remove) the heat by transferring it to the surrounding air. F117The hoist control lever have two positions,uphole and downhole.F1The hoist in the worker-house can be used by everyone to move the logging tools.F20The Input Impedance of FET transistor is very low.T18The Intel 87C51 is a single-chip control-oriented microcontroller which is fabricated on Intel's reliable CHMOS EPROM technology.F143The machine for manufacture charge holder tube is CNC lathe.T144The machine for manufacture charge holder tube is laser cutter machining.T148The material Hardness commonly denotes "Rockwell hardness " or "Brinell hardness".T146The material mechanical properties of perforating gun include: Tensile Strength,Yield Strength,Elongation,Reduction of Area,Hardness etc.F147The material mechanical properties of perforating gun only include Tensile Strength.T142The material of charge holder tube is welder tubing.F19The negtive pulse makes the resistance between pin D and pin S of N-Channel MOSFET very low. F3The O-Ring oil can be replaced by thread compound.F138The output voltage of diesel generator is normally 120V DC.T145The perforating gun can match charges including deep perforate, super deep, big hole, super big hole and low debris or no debris types.F53The pins of ICs are numbered clockwise around the IC (chip) starting near the notch or dot.T119The speed range control switch has no effect over the back-up hoist control.T136The SPEED RANGE CONTROL SWITCH is used as a course speed adjustment by the operator.F108The surface and the pitch circle and the bottom of the tooth.T60The voltage and power (or current) ratings are usually printed or embossed on the body of a lamp.T35There are many types of capacitor but they can be split into two groups, polarised and unpolarised F84There are two types of all transistors, NPN and PNP.T95Thermistors with a negative temperature coefficient (NTC) means their resistance decreases as their temperature increases.T16These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.T10Thread protectors should always be installed when transporting instrument to aid in securing or handling tool. T70Transistors and ICs must be protected from the brief high voltage produced when a relay coil is switched off.F81Transistors are used to amplify current only.F89Transistors can not be damaged by heat when solderingF86Transistors have three leads which be connected no matter the way round.F37Unpolarised capacitors are small value and must be connected correct way round.T38Variable capacitors are mostly used in radio tuning circuits and they are sometimes called 'tuning capacitors'. T93Variable resistors are often called potentiometers in books and catalogues.T92Variable resistors consist of a resistance track with connections at both ends and a wiper which moves along the track as you turn the spindle.T23Voltage and Current are vital to understanding electronics, but they are quite hard to grasp because we can't see them directly.F25Voltage is measured with a voltmeter, connected in series.F30Voltages are the same across all components connected in series.T107We can alter the characteristics of steel in various ways.T116We can alter the characteristics of steel in various ways.F120we increase engine throttle control,the injectors will be delived little amount of fuel.T7We must apply Lubriplate to the threads of the pressure housingF40When a reverse voltage is applied a perfect diode does not conduct, no diodes leak current .F2When we make the insulate check,either megger or multimeter can be used.T T91You can use a multimeter or a simple tester (battery, resistor and LED) to check the transistorF F42You can use a multimeter or a simple tester (battery, resistor and LED) to check that a diode conducts in two directions.F F74You may have noticed that resistors are available with every possible value.T T49Zener diodes are designed to 'breakdown' in a reliable and non-destructive way so that they can be used in reverse to maintain a fixed voltage across their terminals.T T48Zener diodes are used to maintain a fixed voltage.F F50Zener diodes can not be distinguished from ordinary diodes easily .T T26Zero volts could be any point in the circuit, but to be consistent it is normally the negative terminal of the battery or power supply.判断题答案序号中中难难易中中中中中难难易中难易中难中中易中易易易易易易中中中中易难易易中易易中易易难中中中易难难难易易中易中易中中难中易易易易易中中易易难中中中易中难易中中难易易难易中易难中中易易难中易中难难易中难难易程度。

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。

机电工程专业英语答案【篇一：机电工程专业英语】r (rotating member) in an electric motor has rotational inertia,and a torque is required to bring it up to speed when the motoris started. if the motor shaft is rigidly connected to a load witha large rotational inertia, and the motor is started suddenly by closing a switch, the motor may not have sufficient torquecapacity to bring the motor shaft up to speed before thewindings in the motor are burned out by the excessive current demands . a clutch between the motor and the load shafts will restrict the starting torque on the motor to that required to accelerate the rotor and parts of the clutch only.电机的转子（转动元件之一）是有惯性的。

当电机启动时，需要一个力矩使转子提升速度。

如果电机轴与负荷是刚性连接，就会有更大的惯性。

这样启动，电机在还没有足够的力矩使转子提升到一定速度，可能就被过电流烧毁了线圈。

在电机和负荷之间的离合器，会限制启动转矩来保证有足够的力矩只加速转子和离合器。

有些机床，可以非常方便的在电机连续运转时，通过操作离合器来启动或停止机器的。
