我船于2005年8月12日在上海对轮机以下循环检验项目进行了检验： 

主机第一缸的气缸盖、气缸套、活塞、十字头轴承及连杆大端轴承。十字头轴承下瓦发现合金严重剥离，已用新配件换上。其他项目经检验情况正常。

 航行期间，主机1号气缸发出敲击声，经确认敲击声来自气缸内部。停止主机，更换了1号气缸的油头之后，进行了排气阀和燃油泵的检查和调整, 重新起动主机恢复航行，但还是发生了同样的敲击声，当转速减至53转时，这些声音停止。

请公司给予指示。

One reason why the Convention has received such wide acceptance is _____.

• A.that it is only the minimum standards
• B.that it is the obligatory standards
• C.that it is established by IMO
• D.difficulties could arise for ships entitled to fly the flag of a Non-Party State

One especially important feature of the STCW Convention is _____.

• A.the adoption of the policy “ more favorable treatment”
• B.“ no more favorable treatment” to Non-parties of the convention
• C.the adoption of the minimum standards
• D.the adoption of the obligatory standards

材料：

The 1978 STCW Convention was the first to establish basic requirements on training, certification and watch-keeping for seafarers on an international level. Previously the standards of training, certification and watch-keeping of officers and ratings were established by individual governments, usually without reference to practices in other countries. As a result standards and procedures varied widely, even though shipping is the most international of all industries. 

The Convention prescribes minimum standards relating to training, certification and watch-keeping for seafarers which countries are obliged to meet or exceed. 

The Convention did not deal with manning levels: IMO provisions in this area are covered by regulation 13 of Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), 1974, whose requirements are backed up by resolution A.890(21) Principles of safe manning, adopted by the IMO Assembly in 1999, which replaced an earlier resolution A.481(XII) adopted in 1981.

The Articles of the Convention include requirements relating to issues surrounding certification and Port State Control. 

One especially important feature of the Convention is that it applies to ships of non-party States when visiting ports of States which are Parties to the Convention. Article X requires Parties to apply the control measures to ships of all flags to the extent necessary to ensure that no more favorable treatment is given to ships entitled to fly the flag of a State which is not a Party than is given to ships entitled to fly the flag of a State that is a Party.

The difficulties which could arise for ships of States which are not Parties to the Convention is one reason why the Convention has received such wide acceptance. By December 2000, the STCW Convention had 135 Parties, representing 97.53 percent of world shipping tonnage.

材料：

Spark erosion is caused by a voltage discharge between the main bearing and journal surface. The cause of the potential is the development of a galvanic element between the ship’s hull, sea water, and the propeller shaft/crankshaft.

The oil film acts as a dielectric. The puncture voltage in the bearing depends on the thickness of the oil film. With increasing engine ratings, the specific load in the main bearing is increased. his will reduce the oil film thickness, and enable the discharge to take place at a lower voltage level.

Since the hydrodynamic oil film thickness varies through a rotation cycle, the discharge will take place at roughly the same instant during each rotation cycle, i.e. when the film thickness is at its minimum. The roughening will accordingly be concentrated in certain areas on the journal surface. In the early stages, the roughened areas can resemble pitting erosion. but later, as the roughness increases, the small craters will scrape off and pick up white metal-hence the silvery white appearance.

Therefore, to ensure protection against spark erosion, the potential level must be kept at maximum 80 mV, which is feasible today with a high efficiency earthing device. If an earthing device is installed, its effectiveness must be checked regularly. Spark erosion is only observed in main bearings and main bearing journals. 

问题：

• According to the paragraph one, a voltage between the main bearing and journal surface is produced by______.
• A.propeller rotation
• B.leakage from M/E electric control unit
• C.a galvanic element
• D.friction between the main bearing and journal surface
