In C, a block of code is a logically connected group of program statements that can be treated as a unit. You can create a block of code by placing lines of code between opening and closing curly braces. For example: if(x<10) { printf (“too low, try again”); reset_counter(-1); } The two statements after "if" that are between the curly braces are executed if x is less than 10. These two statements with the braces represent a block of code. They are linked together: one of the statements cannot execute without the other also executing.

电子电气员英语口试题船舶电子电气员英语口试试题----------------------------------------------------------------------------------- I.朗读：（20%）It is known to all that the propulsion plant of a ship is often compared to one’s heart and the hull to one’s body. Main propulsion power plant is m ade up of the main engine, the shafting system and propeller. The main engine produces the driving power as a prime mover. The ship is propelled by propellers and in most cases by only one. The propeller is rotated via a shafting system usually driven by a diesel engine.II.口述：（20%）Talking about the Navigational aids.There are several navigational aids on bard a ship. The typical navaids are divided into traditional and modern type. The traditional type includes sextant, magnetic compass, chronometers, barometric, etc. The modern type includes radar, ARPA, ECDICS, AIS, etc. Modern navaids are highly related to the ETO’s responsibilities, since they are liable to break down under different circumstance. Most problems for navaids lie in the hardware such as power supply system or software, such as malfunctions. Therefore, it is necessary to get familiar with the navaids on board.

From the pump water is supplied to the engine manifold (总管) which is cast in the engine block. From the manifold the water is distributed to all cylinder liner sections and from each liner upwards through the cooling water channels in the liner collars. From the liner collars further into the cylinder heads. In the cylinder head the water is forced by an intermediate deck to flow along the flame plate, around the valves to the exhaust valve seats and up along the fuel injector sleeve. From the cylinder head the water is discharged via a connection piece into the discharge manifold.The return water from the cylinder heads and turbocharger is supplied to the HT air cooler.In the first stage of this cooler, most of the heat from the charge air is extracted. The LT circuit water cools the charge air in the second stage. The necessary cooling for the LT water is gained from a central cooler. By controlling the LT water temperature to the inter-cooler the correct charge air temperature can be obtained. For preheating purposes, a heater circuit with a pump and heater are connected in the HT circuit before the engine. Before starting, the HT circuit is heated till about 60℃ by a separate heater The pre-heating of the engine is, prior of starting up and loading on HFO, of utmost importance.1. From the passage we know that the charge air temperaturewas controlled by ____.A. sea water from a central coolerB. fresh water from a central coolerC. fresh water from a HT circuitD. fresh water from the LT circuit2. The cooling water to cool the engine was forced ______ .A. into the cylinder liner and then upwards into the cylinder headB. into the cylinder intermediate section and then upwards into the cylinder headC. into the cylinder head and then downwards into the cylinder blockD. into the cylinder ends and then further into the cylinder intermediate3. After the charge air is discharged into the HT air cooler, _______.A. the charge air temperature will become higherB. the charge air temperature will become lowerC. the HT water temperature will remain constantD. the HT water temperature will become lower4. Which of the following devices may be used to warm the engine prior to starting?A. A high temperature cooling water system.B. A low temperature cooling water system.C. A central cooler.D. The second stage cooler.Passage 2The field current supply in order machines comes from a lower voltage direct current generator or exciter on the same shaft as the alternator. Modern “machines”however are eitherstatically excited or of the high-speed brushless 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 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 is considerable. 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.1. The word “machines” in the passage refers to _______.A. the direct current generatorB. the alternating current generatorC. the exciterD. the prime mover2. 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.3. When the load has a lagging power factor this voltagedrop is considerable. This sentence means 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 load.C. when the load is the capacitive load combined with resistance load, the voltage drops to zero.D. when the load is the inductive load combined with resistance load, the voltage drop is fairly large4. The exciter must vary with: (1) load current, (2) the power factor, (3) speed change of the prime mover.A. only (1)B. only (2)C. (1) and (2)D. (1)、(2) and (3)。
