轮机实习生英语实习题

1.Please describe your ship in brief.Our ship was made in china in 1994, the name is NING AN 15.It has 7 cargo-boxes, the gross registered tonnage are 26420 tons.The length overall of the vessel is 185m.The port of registry is Guangzhou.There are two main engines, three A/E, tow fresh water generator, two fuel and exhaust gas combined boilers, etc in engine room.2.Do you like your occupation? And are you confidence to be an excellent engineer after 12

months?

Yes.I like my occupation very much and I confidence to be an excellent engineer after 12 months.3.What works should you do when you are on duty(watch-keeping)?

⑴ At the beginning of the watch the current operational parameters and the condition of all machinery should be verified and also the log readings should correspond with those observed.⑵ The engineer officer in charge should note if there are any special orders or instructions relating to the operation of the main machinery.4.What should you do when standby engine?

⑴ Warming: It should be approx cooling water transferred from the rounding A/E to the M/E cooling water system, or should be used the steam for warming the M/E cooling water.⑵ Reading for lube oil system: check that the lube oil cycle tank.Start if the main lube pump and check pressures.Since one hand operating the cylinder lubricators.⑶ Ready for cooling water system: check that the level of M/E water tank and all valves in the various system are operational.tart the main engine C·W pump.After the M/E rounding, main sea water pumps working when the system temperature rises.⑷ Reading for compress air system: pump up the starting air reservoirs to their maximum pressure and drain the air reservoirs and air system.⑸ Reading for fuel oil system: check that the level of M/E setting tank and DO, FO serve tank.If you found the level down, you must be bunker the oil.⑹ Turning: start the turning gear, and with the indicator cocks open, and with the control gear in the ‘stop’ position, give the engine at least one complete turn.⑺ Starting: inform bridge that engine-room would like to turn engine.During the engine is turning check to see that no water and sludge leaking from the indicator cocks, start the engine on air briefly on both direction and then close all indicator cocks.⑻ Finally: before ‘standby’ is rung on the engine telegraph, it is necessary to give the main diesel engine a brief trial on power ahead and astern.5.What is the difference between 2-stroke engine and 4-stroke engine?

⑴ In the two-stroke engine, revolution of the crankshaft makes one power or working stroke, while in the four-stroke engine, it takes two revolutions to make one power stroke.That is why a two-stroke cycle engine will theoretically develop twice the power of a four-stroke engine of the same size.Inefficient scavenging and other losses, however reduce the power advantage to about 1.8.⑵ Due to the gas exhaust mechanism of 2-stroke engine is simply, so the construction of the 2-stroke is simple than 4-stroke engine.⑶ The gas exchange quality of 4-stroke engine is better than 2-stroke engine.⑷ The thermal load of 2-stroke is high than 4-stroke engine.6.What is the main reason when you see black(blue, yellow, white)smoke exhausted from the

diesel engine?

⑴ Black smoke: ① Air supply too low clue to fouling of air and gas passages.② fuel valves or atomizers defective.⑵ Yellow smoke: sulfur too high.⑶ Blue smoke: too much lube oil.⑷ White smoke: There is more water in fuel oil.7.How do you take a generator on load?

If we will want to take a generator on load, we can employ parallel operation.To parallel an incoming machine to a running machine therefore it is necessary to ensure firstly that both voltages and frequency.Voltmeters are provided for this purpose.Secondly the frequencies and phase must be brought into phase.In practice the synchroscope usually more slowly in the fast direction and the paralleling switch is closed as the pointer reached the 11 position.This results in the incoming machine immediately accepting a small amount of load.8.Draw a sketch to explain the principle of Fresh Water Generator.This is the vacuum boiling evaporator.Look for this picture of its principle.It makes use of the sea water boil produce the water steam, and through condenser produce fresh water.Usually the heater is cooling water of main engine cylinder.The total boiling is carrying out inside the vacuum, so we have to use a vacuum pump, and keep in vacuum about 1.1MPa.The important thing that we have to keep in the salinity of fresh water low to a fix value, so we install a salinity indicator on the distillate line.9.Draw a sketch to explain the principle of oily-water separator.The complete plant consists of a separator, a filter, a screw pump and a bilge alarm.The oil/water mixture is pumped into the separator by the screw pump.The preliminary separation then takes place in the separator according to the gravity principle.The oil to be separated rises into the oil collecting tank in the upper part of the separator.The de-oiled water leaves the filter for the remaining separation.The filter is fine oil separator oil rises into the oil collecting space too, and the water to the sea, but the important thing: the density must be low to 15PPM, so we install a visual alarming.The oil of collecting space is drained into the used oil tank.10.Draw a sketch to show the inside of oil-fried boiler? What safety devices the boiler provided

and how to check them?

The picture shows the inside of oil-fired boiler, look at it.The safety devices include the safety valves and the feel water system.⑴ The safety valves: There are mounted in pairs to protect the boiler against overpressure.Once the valve lifting pressure is set in the presence of a surveyor it is looked and can not be changed.The valve is arranged to open automatically at the pre-set blow off pressure.⑵ Feed water system: Frequent comparison of drum-mounted and remote-reading water level indicators: discrepancies between these have contributed to failures because of overheating through shortage of water, when a boiler was being oil fired.If in doubt as to the true boiler water level, i.e.whether a water level indicator sight glass is completely full or empty, when a unit is being oil-fired the fire should be immediately extinguished until the true level is resolved.11.Draw a sketch to describe the principle of Sewage Treatment plant? And how to maintain?

A number of biological sewage treatment plant types are in use at sea but nearly all work on what is called the extended aeration process.Basically the consists of oxygenating the liquor either by bubbling air through it or by agitating the surface.By so doing a family of bacteria is propagated which thrives on the oxygen content and digests the sewage to produce an innocuous sludge.The impression that bubbling air through the sewage serves to oxidize it thus reducing BOD is not strictly the case.It is the bacteria that reduce the BOD by converting the organic content of the sewage to a chemically and organically inert sludge.In order to exist, the bacteria need air and nutrient.The nutrient is in the form of body and galley wastes.If the nutrient source is cut off, i.e.the plant shut down or by-passed for say an extended ocean passage, the bacteria die and the plant cannot function correctly until new bacteria colony is generated.12.What do you need to clock before and after start the life-boat engine?

Before start the life boat engine: We have to check the cylinder of diesel engine having or don’t having other things, check the diesel oil and lube oil level of tanks, adjust the diesel engine throttle controlling at max for starting easy.After start the life-boat engine: We have to check the pressure of lube oil.Look at the smoke color exhaust or listen to the sound from the diesel engine.If we found the abnormal condition, we must be found out reason as soon as possible.We also need to check the change diction.13.What is the principle of incinerator and have you burnt the sludge?

There is an incinerator in our ship, and I have burnt the sludge just several times because most of the sludge in our ship was push away by the people from port.The principle of incinerator was like the boiler.14.Explain in brief how to write down the oil record book.Oil Record Book part Ⅰshall be provided to every oil tank of 150 tons gross tonnage and above and every ship of 400 tons gross tonnage and above, other than oil tankers, to record relevant machinery space operations, for oil tanks, Oil Record Book part Ⅱshall also be provided to record relevant cargo/ballast operations when making entries in the Oil Record Book, the date, operation code and item number shall be inserted in the appropriate columns and the required particulars shall be recorded

chronologically in the blank spaces.15.What is the difference between the centrifugal pump and screw pump? How to start a

centrifugal pump?

⑴ The screw pump are positive displacement type pumps.Displacement pumps are those where the volume of the pump chamber is alternately increased to draw the liquid in from the suction pipe and then decreased to force the liquid out into the delivery pipe.⑵ Centrifugal pumps are those where in an impeller rotating at high speed throws the liquid by centrifugal force from the centre to the periphery of the impeller where the liquid is discharged through the delivery outlet.Unlike the screw pumps, the centrifugal pumps do not have a positive suction action.⑶ Due to the centrifugal pump does not have a positive suction action and must be primed by flooding before it will draw water from a lower level starting.An air pump or a central priming system may be used for this purpose.We will have to close the discharge valve before a centrifugal pump starting.Because of centrifugal pumps are no positive and fairly low pressure units.Here a closed discharge valve will not cause excessive pressure to build up.16.What is your duty in emergency drills(Life-saving, Fire-fighting, Pollution prevention)?

Life-saving: Lay out embarkation ladder and take care of embarkation.Fire-fighting: Prepare team, carry extinguishers waiting on the scene.Pollution prevention: Carry cotton yarns and remora and clean spill oil.17.What action will you take if you find a small fire in E/R?

About this question I think the important thing that I approve the fire whether or not small.If I find a small fire in E/R, I will extinguish the fire first.18.What action will you take if you find your ship spilling oil?

If I find our ship spilling oil, I will call C/E to the scene and start the muster lists for vessel.19.What precaution will you take when you do the special work(Hot work, Enter a enclosed

space)?

Hot work: We will check the scene whether or not safety and whether or not ready for extinguish equipments.We will wear work clothes and the protect gloves.Enter an enclosed space: We will pass the enough air first and must be have enough lighting.Assign a man look after the enter man at the enter space and ready for some emergency equipments.The enter man must be know contact signal and the way of run for its life.20.What is PSC/FSC/ISPS?

PSC: Port state control.FSC: Flag state control.ISPS: International safety port of ship.

sci论文投稿指南 篇6

sci论文投稿百分百录用

总是让人又爱又恨,要是通过审核,那简直是欢天喜地,得意洋洋地在各个论坛里宣布这个好消息,顺便得瑟一下,但是万一没通过,又有着这个“傲骨”不重复投递,那就要哭天抢地了,花了这么长时间不说,对自己的能力也会有所怀疑,小编也曾经历过这种惨痛时光,因此想要给大家支些招,让大家早日脱离苦海。的第一步是要有稿可投,稿件质量就是金字塔的底部,要是你连底都没有打好,这个金字塔当然是建不起来的,论文到底怎么写?写的时候要注意什么?在《sci论文写作经验高分发表总结》和《sci论文写作范文精简版》等文章中小编已经不厌其烦地教过大家啦,第二步是什么?当然是投稿,投稿之前要选好sci期刊,有很多人在选择sci期刊时有一个硬性标准,就是影响因子,sci影响因子就是sci期刊前两年收录的文章在这一次被引用的次数,然后经过一些算法算出来的指标,大家也可以猜到影响因子越高,这个期刊的影响力和水平也就越高,大家量力而为就好,一般小编选择2到4的期刊,这个区间的期刊学术性也有,发表难度也没有那么大。的问题小编就讲到这里,要是你还没有看过瘾,英文不好也能SCI投稿成功》介绍了英文sci论文的投稿过程。

SCI论文投稿心得 篇7

编辑部一天网上投稿没有千儿也有八百,切记勿匆忙投稿(有很多人都急于求快投稿,从高往下投,希望reviewer来帮你写文章,结果很理想,我曾经就这样做过,结果反而浪费很多时间)。 editor 和reviewer一天要审大量的稿件,如果一眼看下去漏洞百出,缺乏逻辑,就会非常快地告诉你(通常1周吧):Weapologize to inform you……。 因此,文章从大的方面来说要深入浅出,reasonablyorganized; 其次是没有语法和表达上的错误(这点没有办法突然提高,主要靠平时多读文献,多积累,获得语感,否则就会被reviewer说成是英文不nativeand cause some confusion, 这个评语大家从师兄师姐那里听到的应该很多了,另外,拼写错误要避免!reviewer认为字母都会拉掉的人,其研究质量也好不到那里去。Reviewer工作一天回来很累了,拿起一篇文章是为了享受的,如果你的文章破坏了他的心情或是让他反胃,你就没指望了。一般文章初稿写成以后都要拿给别人看,请别人多提意见,大多情况下是你老板和师兄师姐,最好再多找1-2老师看看,看的人越多,你的问题就会少,中稿的机会就越大。如果你的文章连专业和非专业的人都能理解,初稿就可以定稿了。

2.投稿后要调整心态。

初投稿的人都希望一投稿就马上有回复,或者没到时间就写信去催,这是很不礼貌的。一般来说,正规杂志不用催,到了承诺的时间就会给你回信。因此,不要一投稿就希望马上有回复,除非你是大牛,但我想我们当中没有(包括你老板),只有杂志邀请的Reviewer才可能。我的文章一般是2-3个月给的回信。送一句话给正在投稿的朋友,可能会有助于调整心态:文章审的越久,说明Reviewer越难找到你的漏洞;文章在他手上越长,说明他越喜欢你,心得体会《SCI论文投稿心得》。这样想你大概会开心一些的。

3.怎样修回。

如果你的文章修回了,说明编辑给了你一个机会,记住仅仅是机会,而不是接受的承诺,因此精心准备修回是非常关键的。这时切记无匆匆修回!修回一旦发现问题是没办法收回的。2-3个月都等了,还在乎多等一段时间,一般小修花上2-3周修回还是不过分的(一般小修为1个月)。大修最好控制在2-2个半月(一般大修为3个月)。呵呵,我曾经一篇文章急匆匆修回,结果被反复折腾了一年多,除了个人根据本专业回答问题以外,我这里要提醒大家的主要是语气。我建议采用不亢不卑+自信的语气。编辑不希望你这个人太弱,当然也不希望遇到一个没礼貌的家伙。我见过一个家伙先花了半页纸恭维了大半天+自扁了大半天,效果也不怎么样。编辑的工作说来都是公式化的东西,其时间有限,一眼看下去还没有看到想看的解释,心情肯定不爽。所以建议一两句必要的客套话后,直接进入主题,采用Q:A:式的方法,条理清晰。在修回时,最头痛的是如何满足个别reviewer的“不可实现”的要求。我建议主要是引用理论和文献加以解释,作到精练有逻辑有说服力。毕竟,写比做还是要简单些。效果吗,就要看个人的写作能力和编辑的心情了。当然,你能补数据和你有时间补数据的例外。

4.如何看待外面收费代修文章。

有的`同学对此寄予很高厚望,认为是国外的修改就一定录用。我不知到大家实验室外送修回的稿件投出去接受的几率是否明显增高?但是,我的意见是不要过多依赖别人,我的文章一开始是送出去修的,结果一样被拒。后来我看了大量类似的文献,反复修稿自己的手稿,竟然发现自己前后两同一篇文章,却有本质的差别,就连内容都不一样。有时候帮别人改文章,由于跨专业跨的太远,简直改起来痛苦死了。改的时候最好让作者在旁边先搞清楚它想说什么,再用专业英语把它写出来。我得出的体会是,改文章要和作者相互沟通,要尽心尽力!否则就是英国人帮你,你的文章还是逻辑性不强。至于尽心尽力,我想外面的商业机构是很难作到的。

哦,忘了说初稿修改的量化指标,我想6-7遍至少是要的(当然投2.0以下的改4-5遍也可以)。拖太长时间,老板会没耐心的,挨骂是少不了的。呵呵,初写文章的人,改上十来篇一点也不过分,这还得有导师,师兄师姐帮你把把关,呵呵,我现在的文章,初稿自己至少也得改10遍,才勉强像个文章。

如何写SCI文章总结 篇8

王xx 机械工程

1xxxxx03 通过几个星期的SCI写作培训,自己对写SCI文章有了一定的了解,自己之前认为SCI离自己太远,自己完全不可能写的出来,但是自己现在认为写SCI文章有一定的套路,只要按照这个套路来,写出一篇SCI文章来根本不是问题。

在写文章时,自己的时间分配和修改次数都要有一定的规划:30%的时间细心思考,70%的时间认真写作初稿;把写好的论文放一段时间;逐字逐句地阅读论文;请其他人帮助阅读和修改;在修改的时候,从别人的角度来审视论文(Reviewer / boss / colleagues / proof-reader);仔细修改的次数 > 3;修改的总次数 > 5。要点:自己读自己的论文很乏味,并且不易找到错误;为了论文的小的层次提升,要付出大量劳动。

SCI文章大概有五个部分组成,包括:摘要、介绍、方法、结果和总结,它们之间的写作顺序也有一定的说法。

1、写出3~4层的纲要反复修改多次。

2、从Introduction开写,回顾已有的工作。

3、要声明文章结构,不要直接进入细节。

4、声明工作的动机和基本原理,提出潜在的问题,自己进行回答。

5、讲明自己工作与前人的不同,说明自己的贡献及其实际应用前景。

6、最后写Summary和Abstract,反复斟酌后确定标题。

下面重点来介绍摘要、介绍、方法、结果和总结这五个部分该怎么写,改写哪些内容。1.Introduction: 问题的提出;研究的现状及背景;以前工作基础;本工作的目的;思路(可提假说);对象;方法;结果。在… 模型上,观察 … 指标,以探讨 …(目的)。2.M & M ⑴ 材料的写法和意义;伦理.⑵ 程序与指标。操作程序:能序贯,可操作性;方法:多指标方法的排序;引出参照文献简述;改良之处;哪些详或简?⑶ 统计学处理 3.Results ⑴指标归类描述,忌流水帐。不分析不解释,但要体现思路 ⑵ 文字、图、表相对独立,但避免重复 ⑶ 避免统计错误:对照,均衡,随即,重复。计量-计数、绝对值-相对值、专一指标—综合指标的转换。盲判与非盲判。技术资料直接概率法与卡方检验;多组资料与两组资料;等级相关与直线相关;多因素与单因素分析;配对资料与独立样本资料;非正态分布资料;例数不当;平行管,混合样本;突出差异(绝对值,Δ值,变化%; 联合×、÷比值,分亚组等)有效位数的保留。统计学结论与专业结论。4.Discussion ⑴ 背景材料:展开问题的提出;有关本研究的一些基本知识内容(不要离题太远)。⑵ 本实验结果分析:各指标的意义(与文献值比较),结果说明什么问题。⑶进一步对结果机理分析:结合文献 ⑷本工作的意义、结语或小结,进一步提出的新问题 其它注意点:①引证讨论文献知识太多(不同于学位论文),掩盖了本工作的贡献 ②分析不合逻辑,结论不当 ③讨论太浮浅,文献知识不熟悉 ④写成工作总结,缺乏学术高度 ⑤ 要正确使用缩写词,尤其是组别缩写词;5.摘要:问题的提出(Background);本工作目的;对象;方法(指标,分组);主要结果(数据,统计);结论与展望。

写SCI论文的技巧 篇9

如果是这边学校的,SCI论文的奖励是拿不到的(在我成功签证后),而且也不算

是 到了那边的科研成果,岂不是两头都吃亏!那是在01年的暑假期间完成的,直

到 我完全放弃了出国的念头,才在02年的开始将他们投稿出去。其中一篇在稍加

修改后 很快就被接收了(JAP),另一篇直到现在才被接收(JAP),期中改了三稿

,快烦死我了。 这两篇文章的想法完全不同于别人的思路,我从液晶显示器的响

应时间方面寻找响应速度 更快的显示模式,别人是从传统的方式来进行改造显示

模式来达到快速响应的。因此,此两篇文章的被接收应该是意料之中的,只不过第

二篇的修改要累死人的,增加了很多 内容,才使得审稿人的审稿。

当这两篇论文投出之后,在与导师的谈话中,他提到了一种新型要求的显示模式。

至今没有人能提出过,而这个消息是从生产厂家得到的,因此,该模式的研究必

然是 全新的,也将是首创的。我用了半个月的时间思考这个问题。终于得到能实

现这种要求的 一种模式,但是很初步,于是进行了简单的.模拟,便将此结果投稿

的JJAP的short note 上去了,很快就被接收了。还是很简单的,关键是你的想法

是否新颖!

第二点,你的想法的新颖性也是文章被接收的重要条件,也就是说,你的文章如何

从 众多的投稿中脱颖而出,这就是一个法宝。也可以说成是想问题的角度不要墨

守陈规!

本来想换一个题目的,一是因为不再是写作的技巧了,而是因为很多人 比较反感

写SCI的东东了。但是,因为与前面几篇是相互照应的,所以请原谅 我在写着一篇

经验谈——the end

前面写了我的三篇文章的出炉过程,下面是我的另外两篇文章的过程,也将引出我

Abstract –In asymmetric fingerprinting, the merchant can trace the traitors from a pirated copy by

means of the embedded unique fingerprint, while the customer is immune of being framed due to the asymmetric property.In this letter, we propose an asymmetric fingerprinting scheme based on 1-out-of-n oblivious transfer, which is efficient from the bandwidth usage point of view.First, multicast that is an efficient transport technology for one-to-many communication is exploited, which can reduce the bandwidth usage significantly.Second, symmetric encryption instead of public-key encryption is performed on the multimedia content, which can reduce the complexity and communication cost.Keywords: Asymmetric Fingerprinting, Oblivious Transfer, Multicast
