主题： 翻译

1、man marine diesel engine man

the latest large bore two storke man, engine is the ksz 90/163b series in cylinder number from 6 to 12 and developing2,700kw(3,672hp)/cyl. the engine operates at 122r/min, with an m.e.p of 13bar and a mean piston speed of 6.5m/s.

the bedplate is of fabricated design and consists of weo i-shaped longitudinal girders with transverse menbers into which the cast steel bearing housings are welded. the thrust bearing casting is incorporated into the bedplate.

columns have been replaced by frames constructed of box shaped longitudinal girders. thew fabricated top and bottom sections run the full length of the engine and are mounted on the bedplate. such an engine frame helps to stiffen the engine and so protect the bearings from the deformation forces transmitted via the ship's double bottom. the cast iron guideways for the crosshead are attached to the top section and seal off the crankcase.

the cylinder jackets are individual castings bolted together to form one

continuous member. the one piece cylinder liners are fitted into the jackets from the top and a cast steel strong back is fitted in way of the combustion space to help absorb gas forces. the scavenge process is the man loop system and the scavenge and wxhaust ports are arranged in two tiers and are carried far around the liner. the vertical lands between the ports are cooled by water passing hrough cast in tubes and hence to passages arranged around the liner above the exhaust ports.

each cylinder cover is in two parts, the lower section is of special (更多内容请访问首页www.HAowOrd.COM)thin walled forged steel permitting the area in way of the combustion gases to be intensively cooled whilst absorbing thermal stresses and this is held in position by an upper supporting unit of cast iron, which transmits the gas forces to the cylinder jackets via long studs. the joint face between the cylinder cover and the liner is arranged as far from the combustion process as possible. the gas loads on the engine structure are constrained by means of hydraulic preloaded tie rods which connect the bedplate, frame sections and cylinder jackets into a single unit.

the crankshaft is of the semi-built tybe, with the journal being shrunk into the forged or cast steel crank throws. with the exception of the six-cylinder engine, it is in two arts joined by fitted bolts. the coupling flange for attachment to the propeller shaft also accommodates the turning gear and is integrally forged with the crankshaft. the aft end section also incorporates a thrust collar. the drive for the camshaft gear train is taken from a spur gear which for a six cylinder engine is the couping end and for 7 to 12 sylinder engines the drive is located in the middle

of the engine.

the piston crown is of forged steel and is designed for intensive cooling; the central supporting body is of cast steel and is mainly suvjected to compressive stress. the two components are bolted together and connected to the piston rod. a single piece piston skirt fitted with bronze rings guides the piston in the cylinder liner. the piston ring grooves for a standard engine are flame hardened against wear.the crosshead pin bearings are whte metal lined shells lubricated by means of highpressure pumps. the piston forces are transmitted over the entire length of the crosshead pin then to the connecting rod via the lower half single bearing shell. the principle of hydrostatic lubrication has been applied to the crosshead using high-pressure lubricators. this is achieved by means of high pressure rod,high pressure oil is delivered to the ower part of the crosshead bearing, the pumps press oil film is maintained at all times and on all loads between the journal and the shell.

scavenging of the cylinder liner is on the loop scavenge system and constant pressure of the exhaust gas is used to drive the turbochargers. during running up and in the lower partial load range the turbochargers are assisted by electrically driven auxiliary blowers connected before the compressors of the main blowers. in the upper power range the auxiliary blowers are disconnected. diffusers are fitted in the exhaust system and facilitate charge removal and scavenging in each cylinder. the diffuser also prevents pressure pulses from one cylinder interfering with another during operation.

2、man-b&w mc engine man-b&w mc

man-b&w k90 mc-c engine is a large crosshead tybe two-stroke engine with a broe of 900mm, a 2,300mm stroke and an operating speed of 104r/min. it is constructed with between six and twelve cylinders.

developed as one of the extensive range of the manufacturer's mc engines, it is of the power and speed best suited to large, fast container ships. the increase in running speed is obtained by a slight decrease in engine stroke. high thermal efficiency is maintained by an increase in mean effective pressure(m.e.p.).

construction can be considered generally as typical for the whole range. the engine bedplate is of rigid box form, fabricated from steel plates with main bearing supports of cast steel. welded 'a' frames are assembled into a frame box which contains the crankcase, the crosshead guides and also supports the wheels for the chain drive of the camshaft. a cast iron cylinder frame accommodates the scavenge space between the cylinder jacket and the diaphragm, both of which are water-cooled.

long pre-stressed tie bolts are fitted between the top of the frame and the underside of the bedplate girders.

the cylinder liner is of alloy cast iron, its upper flange lands on top of the frame and has bore cooling. it is secured by a forged steel cylinder cover which is also bore cooled and is shaped internally to accommodate most of the combustion space. cylinder luvricating oil is injected at one level in the liner. pistons have a chrome-molybdenum alloy steel crown with hard chrome-surfaced ring grooves in which four compression rings are fitted. in this particular model a protective layer of inconel is welded to part of the crown surface to prevent high temperature corrosion. the piston is oil cooled, oil being supplied by a telescopic gland to the crosshead and then through the piston rod. it is returned from the crosshead to a slotted pipe in the crankcase. a short cast iron skirt is added. the crown is bolted to the piston rod at an inner support ring.

surface hardening reduces wear on the piston rod at the diaphragm gland. the rod is bolted ata the top of a cylindrical crosshead which is of large diameter and incorporates a full-length bottom half-bearing shell. floating guide shoes are attached at each end.

the crankshaft may be either semi-built up or of welded construcion, with large journals and pins. all crankcase hearings are of white metal. main bearings have thick shells, crankpin( bottom end ) and crosshead(top end) bearing have thin-wall shells. white metal is used for the guide surfaces. the exhaust valves are operated hydraulically under oil pressure from cam-timed actuated pistons. they have air compressed springs which allows them to be rotated by vanes. the valve spindles are usually manufactured by the hot isostatic pressure(hip) method, a compound nimonic and austenitic steel part construction. valve housing is cooling at its seat and spindle guide bush but its upper duct is uncooled to avoid low temperature corrosion.fuel pumps are cam driven and timed by the plunger helix. an adjustable barrel allows variable ignition timing to maintain combustion efficiency at low speed and can be adjusted to match the ignition quality of fuels. pump timing is changed for astern operation by a link connected at the cam roller guide which is activated by compressed air. each pump supplies three identical fuel injectors for the

corresponding unit. injectors are uncooled but they circulate hot fuel oil directly white their needle valves are in the closed position.

the engine operates with a constant pressure system, with uncooled turbochargers. two auxiliary blowers are fitted to operate at low charge air pressure or at low

engine revolutions. a number of waste heat recovery and power take-off systems can be operated under running conditions.

第三篇：文献检索在毕业论文中的应用

文献检索在毕业论文中的应用

中文系093班邓新花

毕业论文通常是一篇较长的有文献资料佐证的学术论文，是高等学校毕业生提交的有一定学术价值和学术水平的文章。它是大学生从理论基础知识学习到从事科学技术研究与创新活动的最初尝试。学生在整个毕业论文写作中需要查找大

量的文献资料，文献资料的查找对一篇毕业论文写作的成功至关重要。

毕业论文选题中的文献检索

毕业论文题目的选定不是一下子就能够确定的.若选择的毕业论文题目范围较大，则写出来的毕业论文内容比较空洞，难以结合实际；而选择的毕业论文题目范围过于狭窄，又难以查找相关文献资料，会让人感到无从下手.对于毕业论文题目的确定，通常可以采取先选出一个大的研究方向，再围绕该研究方向查找文献资料，通过阅读、思考、分析材料逐渐把毕业论文题目范围缩小的方法。

毕业论文材料的收集与整理中的文献检索

通过收集得到的材料一开始没有必要都通读，可以先翻翻目录或索引，找出与毕业论文论文题目有关或紧密相连的章节。通过泛读，大致了解本论题有关的研究现状和前景，避免重复别人的工作。在这些过程中，有几样事情需要做:概括出与毕业论文题目有关的研究现状毕业论文不同于一般的论文，专业的毕业论文是某一学科领域的科研成果的描述与反映，没有研究，写作就无法进行.而研究的一定前提是必须掌握尽可能多的文献信息资料。一个人读的书越多、查找的资料越全面，专业水平就越高，创造性的思考可能性就越大，写出来的论文质量就更高。因此，大学生在写作毕业论文时，首先要学会如何检索文献资料，懂得

文献查找的方法与技巧。

，下面是我所了解的几种可以查阅资料的地方

(1)中国知识基础设施工程网(cnki数据库)。它是由清华同方光盘股份有限公司和清华大学中国学术期刊(光盘版)电子杂志负责牵头实施的.其建立的cnki系列数据库包括期刊、报纸、博硕士毕业论文等，收录了自1994年以来的国内公开出版的6000多种期刊（编者注：现在已达到8400多种）和报纸上发表

的文章的全文。网址是http://.cn或http://。

可见，文献检索知识的应用对于如何写好一篇文章是非常重要的，我相信通过合理的运用，我们一定可以很好的把论文写好。

第五篇：triz理论在工科学生毕业论文中的应用

triz理论在工科学生毕业论文中的应用

当今社会高速发展，创新越来越受企业的重视，也是高校培养人才的重要方向。特别对于工科学生，无论是技术上还是理论上的创新，都可能给企业和社会带来巨大的社会和经济效益。然而，目前高校对工科学生的教育大多以基础理论课程教育为主，创造性、实践性教育环节不够，也使学生自主思考和拓展创新的观念不断弱化。毕业论文的设计过程是学生对所学的基础理论和技能进行运用并创新的过程，是大学生综合素质的具体体现。

但目前很多高校工科学生的毕业论文都流于形式，学生在选题、实验设计、实施的过程中，过分依赖教师的指导，课http:///题内容往往是照搬其他人已有研究的成果，没有自己的创新。因此，在毕业论文设计过程中，加强学生创新精神和创新方法的培养成为当务之急。创新性思维开发的理论有很多，ｔｒｉｚ的英文全称是ｔｈｅｏｒｙ ｏｆｔｈｅ ｓｏｌｕｔｉｏｎ ｏｆ ｉｎｖｅｎｔｉｖｅ ｐｒｏｂｌｅｍｓ（发明问题解决理论），它是基于知识的、面向人的发明问题解决系统化的方法学，是我国科技部大力向全国科技界推广的创新方法论。本文主要探究了ｔｒｉｚ理论在工科毕业论文中的应用，举例说明ｔｒｉｚ理论在纺织工程专业本科毕业论文的选题、实验设计、实施到最后写作的整个过程中所发挥的作用，从而为http:///xingzhengguanli/高校工科学生毕业论文的设计提供一定的参考。

ｔｒｉｚ理论的基本原理ｔｒｉｚ理论是由前苏联发明家阿奇舒勒（ｇ．ｓ．ａｌｔｓｈｕｌｌｅｒ）在研究了大量专利产品开发过程的基础上提出并于１９４６年创立的创新思维方法，经过多年发展，ｔｒｉｚ理论已经形成了一套较为完整的体系。ｔｒｉｚ理论的应用不断从工程技术领域向自然科学、社会科学、生物科学领域渗透，在指导人们创新的过程中发挥着越来越大的作用。ｔｒｉｚ理论提出分析解决问题的方法主要有以下几种：技术矛盾与创新思维方法ｔｒｉｚ理论认为当技术系统某个特性或参数得到改善时，常常会引起另外的特性或参数劣化，该矛盾称为“技术矛盾”。解决这一矛盾可基于创新原理，如九屏幕法、金鱼法、小人法等，并结合工程实际寻求具体的解决方案。
