提醒本资料详情如下：
11规则已经推出很久了，11规则的题库一直在更新和完善中，本资源是破解11规则甲类二副、三副考试最新题库。【航海英语】、【货运于结构】、【船舶管理】等
甲类三副考试（也包括甲类三管轮考试）是船员适任证书考试的入门考试，04考试实行的时候，一般都是一年考试两次，1月份和7月份，后来，推出了人机对话，也就是计算机考试，基本上能做到每个月都有一次三管轮、三副的大证考试。如果按着04规则，那时候题库健全，通过率是很高的。但是，目前实行11规则，各个考试科目的题库都在建设中，三副三管轮考试的习题库也是一样。本资源是破解版的光碟，先下载，解压后运行里面对于科目的文件就可以模仿光碟做题了。给大家提供了两种下载方式：1.下载附件的doc文档，打开里面的网盘地址下载。2.打开下面的地址进行下载：具体用法：下载后解压任意打开即可最后，祝愿参加轮机甲类三副的考生们顺利通过考试~更多资料下载请登录：&

The inspection consists of visually examining the piston, the rings and the lower part of the cylinder liner, directly through the scavenge air ports To reduce the risk of scavenge box fire, remove any oil sludge and carbon deposits in the scavenge air box and receiver in connection with the inspection.The port inspection should be carried out at the first stop after a long voyage, e.g. by anchoring if possible, to obtain the most reliable result with regard to the effectiveness and sufficiency of the cylinder lubrication and the combustion cycle (complete or incomplete)A misleading result may be obtained if the port inspection is carried out after arrival at harbor, since manoeuvring to the quay and low-load running, e.g. river or canal passage, requires increased cylinder oil dosage, i.e. the cylinders are excessively lubricated, Further, during low load, the combustion ccle might not be as effective and complete as expected, due to the actual fuel oil qualities and service (running) condition of the fuel injection equipment. It is highly recommended to take this information into consideration.89. The components of an engine involved in normal scavenge port inspection comprise _______. ①the piston
②piston rings
③the lower part of the cylinder liner
④the fuel injector
B. ①②③④
D. ①②③90. If the scavenge box had too much oil sludge and carbon deposits, what would occur?
A. excessive cylinder oil consumption
B. the scavenge box fireC. the crankcase explosion
D. excessive wear of the cylinder liner91. In order to obtain the most reliable result with regard to the effectiveness and sufficiency of the cylinder lubrication and the combustion cycle, when should the scavenge port inspection be carried out?A. at the first stop after a long voyage, e.g. by anchoring if possible
B. at the first stop after arrival at harbor
C. at the first stop after low load runningD. at the first stop after passing river or canal passage92. Under what condition that the scavenge pot inspection can gain a misleading result?①after passed through Panama Canal ②after got alongside shanghai quay ③after arrival shanghai roadstead (外锚地)A. ②③
D ① 第二组Current regulations with respect to the discharge of oily water set limits of concentration 15 parts per million. A monitor is required to measure these values and provide both continuous records and an alarm where the permitted level is exceeded.The principle used is that of ultra-violet fluorescence. This is the emission of light by a molecule that has absorbed light. During the short interval between absorption and emission, energy is lost and light of a longer wavelength is emitted. Oil fluoresces more readily than water and this provides the means for its detection.A sample is drawn off from the overboard discharge and passes through a sample cell. An ultra-violet light is directed at the sample and the fluorescence is monitored by a photoelectric cell Where an excessive level of contamination is detected an alarm is sounded and diverting valves are operated. The discharging liquid is then passed to a slop tank. 93. The passage is mainly about ________.A. oily water separator
B. current regulations related to oil pollution
C. oil in water monitor
D. the principle of ultra-violet fluorescence494. A monitor can obtain all of the following functions except _______.
A. measuring oil content values
B. providing continuous recordsC. lowering the oil content below 15 ppmD. providing an alarm unit warning of levels of discharge in excess of 15 ppm95. From the passage, we can learn that the ultra-violet fluorescence is a kind of________A. oil sample
C. photoelectric cell
D. alarm unit 96. A sample is drawn off from ______ and passes through a sample cell
A. bilge water
B. discharge of oil separatorC. slop tank
D. discharge of oily water separator45轮机英语的答案1-5
