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。
