MAN-B&W MC_MC-C系列船用低速柴油机的发展及改进
中小学语法大全之冠词a-an-the-及专项练习题--答案
专题六冠词（a an the ）教学目标：1、掌握冠词的概念。
2、掌握定冠词和不定冠词的区别及用法。
3、掌握冠词与名词的搭配。
重点难点：1、重点：定冠词和不定冠词的区别。
2、难点：冠词与名词的搭配。
一、定义：冠词三兄弟a, an和the，它们的任务就是给名词“戴帽子”。
语法上，冠词是虚词，没有词义，用于名词前，帮助表明词义。
冠词三兄弟的分工各有不同，大家一定要记清楚，不要“张冠李戴”。
二、冠词分为两类：不定冠词：a/an定冠词：the●不定冠词a/an只能用于单数名词之前，表示“一”的意思或该名词的不特定性。
●定冠词the则强调该名词的特定性，表示“这”、“这些”等意思，在可数名词与不可数名词之前都能使用。
三、不定冠词a/an的用法：1、a用于以辅音音标开头的单词之前。
a book一本书 a woman一个女人2、an用于以元音音标开头(发音为元音开头)的单词之前。
an apple 一个苹果 an old man 一位老人an hour 一个小时 an egg一个鸡蛋3、当形容词修饰名词时，冠词要放在形容词的前面，这时用a或an取决于这个形容词的读音。
an English teacher一位英语老师 a red apple一个红苹果4、用于第一次提到的、不确定的人或物（可数名词）之前：There is ______dog outside the door 外面有一条狗。
Do you see ______man in red T-shirt?你有看到一个穿红T恤衫的男子吗？5、表示职业、身份：a lawyer一个律师 a doctor 一个医生 a student一位学生6、用于数字、量词之前：a hundred 一百 a lot of 许多 a pair of 一双7、用于一些固定词组中：have a rest休息 go for a walk 散步四、定冠词the的用法定冠词的一般用法：1、用于第二次谈到的人或物。

Unit 6 An old man tried to move the mountains(解析版)
Unit 6 An old man tried to move the mountains1、一个木头人，年岁长了，见人见多了，活了。
木匠一直把他藏在家里，太闷了。
终于有一天，他逃了出去。
他成天见木匠锯锯刨刨，就想试试自己行不行。
于是，他就去锯树。
大树忍不住开口说了话：“木头人，你也曾经是一棵树，可别忘了本。
”2、一粒尘土，被风吹上了天。
尘土居高临下地在天空飞舞。
它高兴地大叫：“我上天了！我上天了！”尘土从高处往下望，觉得自己很伟大，仿佛天底下的一切都比它小。
于是，尘土就有了天马行空的感觉，自由自在地在天空中翱翔。
风终于停了，尘土又落回到地面，一切辉煌都成为过去。
它的上天，不说明它伟大，只能说明它的渺小。
3、纸、墨、笔、砚为了一个共同的事业，走到一起来了。
瞧这哥们四个，白的白，黑的黑；硬的硬，软的软；方的方，长的长。
长相各异，脾气不同，咋就走到一起来了？为了一个共同的事业。
纸是宣纸，墨是徽墨，笔来自浙江，砚来自广东，隔山隔水，非亲非故，咋就走到一起来了？为了一个共同的事业。
因为他们团结，所以被人们并称为“宝”。
4、人们不知道桶里装的是油，还以为是一桶水。
因为从外表观察，不起风不起浪的，根本看不出桶里是油，更像是一桶水。
当人们把油倒掉，重新装上水，人们又以为桶里有很多很多的油。
因为这时水面上漂着一层油花，谁见了都会说桶里有油。
桶里有油是不假，只是那油不过是浮在水面上的薄薄的一层油花。
拓展阅读（一）【语篇来自二十一世纪学生英文报·试题原创】Story with no endBastian Balthazar Bux is a boy with a problem. In fact, he has many problems. His father is doing a bad job raising him, but that’s because Dad has a problem of his own: he cannot get over the death of his wife. Bastian’s life at school is troubled too. The other kids pick on him, leading him to skip school a lot.It doesn’t sound like a fantasy story so far, does it? Fantasy is supposed to take us away from theunpleasantness of life, not rub our noses in it. But this is just where the fantasy begins. One day, running away from bullies at school, Bastian hides in a bookshop. There he finds a book that appeals to him, and he steals it and takes it home.Bastian becomes immersed in the book. It drags him in, just as we are dragged into fantasy books. The book he reads, like the book we read, is called The Neverending Story.The story spellbinds Bastian. It tells of a land called Fantastica. Fantastica is sick, and the person most sick is its ruler, The Childlike Empress.The reason for the sickness is a kind of war that is being waged on Fantastica by a force called Nothing. The Empress asks a boy, Atreyu, to help her battle Nothing before it conquers Fantastica.But what of Bastian, sitting hidden away, reading the story from his stolen book? He becomes part of the tale himself. The Empress gives Bastian a vital job: to join forces with Atreyu in the struggle against Nothing. Now this book, which began as the story of a lonely, bullied, unhappy boy, really becomes a fantasy.But even though Bastian has now entered the pages of a fantasy fiction book, he has brought his troubles with him. He has problems dealing with the challenges brought by his new life. When The Childlike Empress gives him a magic gem called Auryn, he abuses it for selfish ends.Once Bastian finds his true self, he can help the Empress, Atreyu and Fantastica and make his way back into the real world.Like Bastian, we can find ways to solve our troubles with enough commitment. In The Neverending Story, young readers can find a wonderful fantasy that also offers a positive message about their own world.By Paul Brennan,special to 21st Century Teens 1．Why does Bastian skip school a lot?A．Because his father has a bad job.B．Because he cannot get over the death of his mother.C．The other students pick on him.D．Because he doesn’t study well.2．In the author’s opinion, ________.A．Bastian’s encounters are the beginning of his fantasy journeyB．Bastian’s encounters are fantasyC．Fantasy is supposed to take people away from the pleasantness of lifeD．Bastian has a happy life3．________ is the ruler of Fantastica.A．Bastian B．Bastian’s fatherC．The most sick people D．Atreyu4．The underlined word “conquers” means________.A．战斗B．吸引C．屈服D．征服5．This passage is mainly to________.A．tell a story about BastianB．publicize The Neverending StoryC．tell us how to deal with problemsD．introduce Bastian【答案】1．C 2．A 3．C 4．D 5．B【导语】本篇是一篇记叙文。

ME-B Mark 8 Engine Description
Please note that engines built by our licensees are in accordance with MAN Diesel drawings and standards but, in certain cases, some local standards may be applied; however, all spare parts are interchangeable with MAN Diesel designed parts. Some components may differ from MAN Diesel’s design because of local production facilities or the application of local standard components. In the following, reference is made to the item numbers specified in the ‘Extent of Delivery’ (EoD) forms, both for the ‘Basic’ delivery extent and for some ‘Options’. Bedplate and Main Bearing The bedplate is made with the thrust bearing in the aft end of the engine. The bedplate consists of high, welded, longitudinal girders and welded cross girders with cast steel bearing supports. For fitting to the engine seating in the ship, long, elastic holdingdown bolts, and hydraulic tightening tools are used. The bedplate is made without taper for engines mounted on epoxy chocks. The oil pan, which is made of steel plate and is welded to the bedplate, collects the return oil from the forced lubricating and cooling oil system. The oil outlets from the oil pan are normally vertical and are provided with gratings. Horizontal outlets at both ends can be arranged for some cylinder numbers, however, this must be confirmed by the engine builder. The main bearings consist of thin walled steel shells lined with bearing metal. The main bearing bottom shell can be rotated out and in by means of special tools in combination with hydraulic tools for lifting the crankshaft. The shells are kept in position by a bearing cap. Frame Box The frame box is of triangular plate welded or rib design. On the exhaust side, it is provided with relief valves for each cylinder while, on the manoeuvring side, it is provided with a large hinged door for each cylinder. The crosshead guides are welded onto the frame box. The frame box is bolted to the bedplate. The bedplate, frame box and cylinder frame are tightened together by stay bolts. Cylinder Frame and Stuffing Box The cylinder frame is either welded or cast. It is provided with access covers for cleaning the scavenge air space, if required, and for inspection of scavenge ports and piston rings from the manoeuvring side. Together with the cylinder liner, it forms the scavenge air space. The cylinder frame is fitted with pipes for the piston cooling oil inlet. The scavenge air receiver, turbocharger, air cooler box, lubricators and gallery brackets are located on the cylinder frame. At the bottom of the cylinder frame there is a piston rod stuffing box, provided with sealing rings for scavenge air. Oil scraper rings in the stuffing box prevent crankcase oil from coming up into the scavenge air space and polluting the crankcase oil with combustion waste products. Drains from the scavenge air space and the piston rod stuffing box are located at the bottom of the cylinder frame.
MANBW6S50MC-C8柴油机高压油泵工作原理介绍
MANBW6S50MC-C8柴油机高压油泵工作原理介绍一、6S50MC-C8柴油机高压油泵结构特点6S50MC-C8柴油机的每个气缸都单独设有柱塞式高压油泵，将传统的出油阀改为一个独立的吸油阀和一个用来停车的独立的空气刺破阀，因此，6S50MC-C8柴油机高压油泵的主要构件就是柱塞套筒偶件、吸油阀偶件和空气刺破阀偶件。
如图1所示，图左是这种喷油泵的装配图，图中间是刺破阀652组件和吸油阀436组件剖视图，图右是高压油泵的剖视图。
(一)柱塞套筒组件。
包括柱塞556、套筒532、密封圈520和568，套筒中部有对称布置的回油孔。
柱塞上行供油结束时，柱塞上部的高压燃油经此流回进回油空间B。
(二)吸油阀组件。
包括吸油阀座461、滑动吸油阀448、弹簧412和弹簧导套400，吸油阀座中部有一圈数个吸油孔E和进回油腔B相连。
(三)空气刺破阀组件。
包括阀体688、空气活塞664、滑阀723、弹簧735和弹簧座747及密封圈等，刺破阀位于高压油泵顶部，空气活塞上方空间和柴油机控制空气系统相连。
空气活塞上方通入控制空气即可实现柴油机停车或应急停车。
二、高压油泵工作原理正常工作时，刺破阀中空气活塞上方没有控制空气，在弹簧735的作用下，滑阀723上行关闭，隔断高压油泵上方的空间和燃油循环冷却回路。
当柱塞下行时，柱塞将套筒上的回油孔D关闭，柱塞上方空间增大，压力降低。
进/回油空间中压力为0.7MPa的低压燃油经吸油阀体上的油孔E作用在滑阀448下方的环形受压面上，燃油对滑阀施加向上的力，并克服弹簧412向下的弹力和滑阀自身的重力，将滑阀448向上推开，燃油进入柱塞上方空间。
当柱塞运动到底部时，柱塞上部空间C燃油压力和进/回油空间B的压力相等，滑阀448在弹簧412的作用下关闭，隔断柱塞上部燃油空间C和进/回油空间B。
当柱塞上行时，柱塞上方空间燃油压力增加，向高压油管和喷油器供油。
当柱塞头部的斜槽打开套筒上的回油孔D时，柱塞上部的高压燃油经此流回进回油空间B,供油结束。
