Each cargo compartment is individually connected to the smoke detecting cabinet with small bore piping and, by a suction fan mounted on the wheelhouse roof, samples of the air in each cargo space are continually drawn up to the smoke detecting cabinet and discharged into the wheelhouse or the atmosphere through a diverting valve. Thus smoke from a fire in any cargo space can be immediately detected.69. The CO 2 fire extinguishing system may combine with to detect fire in the early stage of firedevelopment.A. a smoke detecting systemB. a wheelhouseC. a cargo compartmentD.a crew‟s cabin70. The function of the smoke sampling system is ______.A. to analyze smoke componentsB. to detect fire in the early stageC. to prevent the wheelhouse from catching a fireD. to ventilate each cargo compartment71. According to this paragraph, which of the following statements is true?A. The smoke sampling system consists of the CO 2 fire extinguishing installation and smokedetecting cabinet.B. The smoke detecting cabinet is located on the wheelhouse roof.C. The suction fan draws samples of the air from cargo spaces.D. Samples of the air flow into the detecting cabinet at regular intervals.72. Which of the following devices does the smoke sampling system consist of?(1)fire extinguishing installation (2) smoke detecting chamber (3) wheelhouse(4) cargo compartment (5) suction fan (6) diverting valveA.(1)、(2)、(5)B. (2)、(4)、(5)C. (3)、(4)、(6)D. (2)、(5)、(6)第二组:Governing prime movers, particularly diesel engines, require careful consideration. The cyclic variations of a diesel cycle can be passed i nto the governor drive if it is too …stiff‟. That is, the cyclicvibrations will be imposed on the internal gearing etc. inside the governor housing. To prevent this, some form of damper should be used on the drive into the governor. The mounting point for the governor should be rigid; a vibration mounting would soon downgrade even the best of governors. Chain or belt drives should be avoided as far as possible, as slapping of the belt or chain produces speed variations causing malfunction of the governor. Similarly the drive from the end of the camshaft is subject to torsional vibrations, and governors should not be located at that point. They should be located as close as practicable to the fuel pumps, thereby limiting the mass/inertia of operating linkage. In all cases, the governor should be matched to the engine requirements in terms of droop, load limiting, response time etc. On large engines there is an inertial resistance to acceleration within the masses of reciprocating and rotating elements of the engine, so that during acceleration fuel could be released to the cylinders at a faster rate than efficient combustion can burn it. In an attempt to compensate for this, and to maintain acceptable combustion during acceleration, a tapping from the scavenge space may be taken and the pressure used to regulate the rate of fuel released to the engine. This process is incorporated into the governor operating system so that the governor releases a quantity of fuel commensurate with the increase in air pressure in the scavenge space.(during deceleration the problem is not so great, as excess air can be tolerated far more easily than can the incomplete combustion associated with insufficient air.)73. This passage is mainly about __.A. mounting the governorsB. the scavenge pressure limit to the governorC. A and BD. how the governor regulates the fuel index74. The drive to the governor ___.A. should be rigidB. should use damperC. should use chains or beltsD. should be from the end of the cam shaft75. The governor should be mounted close to the fuel pumps ___.A. for limiting the inertia effectB. for limiting the loadC. to ensure speed droopD. to cut down the cost76. It can be inferred that with scavenge pressure limit ___.A. the engine can be accelerated rapidlyB. the engine can be decelerated rapidlyC. the governor will supply fuel oil efficientlyD. the combustion will be more complete三、中译英(共2题,请将答案写在答题纸上)77.PSC官员如果发现大量的临时修理,例如管路卡箍和水泥堵漏箱,则表明船舶不愿意进行永久性修理。

The burning of the oil in the cylinders of the diesel engine or gasoline engine provides the ship with driving power. The electrical motor runs on the electrical power. But the generator also consumes oil to produce this kind of power. Beside, the lube oil can reduce the friction between the moving parts of the engine and has much to do with its working condition.69.What do people use to drive a modern ship?A. the windB. the sailC. the oarsD. the machines70.Which of the following does not directly burn oil?A. A gasoline engineB. A diesel engineC. An electrical motorD. None of them71.What does a generator provide?A. driving powerB. a great deal of heatC. frictionD. electricity72.What’s the function of the lube oil?A. to take away the heatB. to reduce frictionC. to remove the detritusD. all of the A.B.C第二组:The field current supply in older machines comes from a lower voltage direct current generator or exciter on the same shaft as the alternator. Modern machines however are either statically excited or of the high-speed brush-less type. The exciter is required to operate to counter the effects of power factor for a given load. The power factor is a measure of the phase difference between voltage and current and is expressed as the cosine of the phase angle.With a purely resistance load the voltage and the current are in phase, giving a power factor of one. The power consumed is therefore the product of voltage and current. Inductive or capacitive loads, combined with resistance loads, produce lagging or leading power factors which have a value less than one. The power consumed is therefore the product of current, voltage and power factor. The alternating current generator supplying a load has a voltage drop resulting from the load. When the load has a lagging power factor this voltage drop isconsiderable.Therefore the exciter, in maintaining the alternator voltage, must vary with load current and also the power factor. The speed change of the prime mover must also be taken into account.73.The word “machines” in the passage refers to ______.A. the direct current generatorB. the alternating current generatorC. the exciterD. the prime mover74.Which of the following statements is true according to the passage ?A. With a purely resistance load, the power factor is zero.B. Inductive loads combined with resistance loads produces leading power factors.C. Capacitive loads combined with resistance loads produces lagging power factors.D. With a purely resistance load, the phase angle is zero.75.When the load has a lagging power factor this voltage drop is considerable. This sentencemeans that _____.A. with a purely resistance load, the voltage drops too muchB. there is a considerable voltage drop in the capacitive load combined with resistance loadC. when the load is the capacitive load combined with resistance load, the voltage drops tozeroD. when the load is the inductive load combined with resistance load, the voltage drop isfairly large76.The exciter must vary with : Ⅰ. load current. Ⅱ. the power factor. Ⅲ. speed change of theprime mover.A. onlyⅠB. only ⅡC.Ⅰand ⅡD.Ⅰ, Ⅱand Ⅲ三.中译英77. 螺旋桨需拆卸,尾轴拉出检查修理,所有拆卸部件重新装妥。
