7、新船员时,应在_进行弃船演习。A.开航前B.开航后12小时内C.开航后24小时内正确答案:A四冲程柴油机曲柄销磨损最大的部位是_。A.外侧B.内侧C.外侧或内侧D.内外侧一样参考答案:B 材料: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
8、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 a
9、nd 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
10、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 is considerable. Therefore the exciter, in maintaining the alternator voltage, must vary with load c
11、urrent and also the power factor. The speed change of the prime mover must also be taken into account.问题: The word “machines” in the passage refers to _.A.the direct current generatorB.the alternating current generatorC.the exciterD.the prime moverWhich of the following statements is true according
12、to the passage ?A.With a purely resistance load, the power factor is zeroB.Inductive loads combined with resistance loads produces leading power factorsC.Capacitive loads combined with resistance loads produces lagging power factorsD.With a purely resistance load, the phase angle is zeroWhen the loa
