毕业设计英文作文范文Title: The Importance of the Graduation Project in Academic Development。

The graduation project holds a pivotal role in the academic journey of students. It serves as a culmination of years of learning, a platform to showcase acquired skills, and an opportunity to delve deep into a specific subject matter. In this essay, I will elaborate on the significance of the graduation project and its impact on academic development.Firstly, the graduation project fosters independent learning and critical thinking skills. Unlike regular coursework where the parameters are often well-defined, the graduation project requires students to identify a research question or a problem statement independently. This process necessitates thorough literature review, data collection, and analysis, thereby honing research and analytical abilities. Moreover, formulating hypotheses, designingexperiments, or proposing solutions demand creativethinking and problem-solving skills, which are essentialfor academic and professional success.Secondly, the graduation project encourages interdisciplinary learning and collaboration. Many projects involve aspects from various fields, prompting students to integrate knowledge acquired from different courses. This interdisciplinary approach not only enriches the project but also broadens students' perspectives, enabling them to appreciate the interconnectedness of different subjects. Furthermore, collaboration with peers, mentors, or industry professionals enhances teamwork, communication, and project management skills, which are indispensable in any academic or professional setting.Additionally, the graduation project cultivates resilience and perseverance. Research, by its nature, is fraught with challenges, setbacks, and uncertainties. Students encounter obstacles ranging from experimental failures to data inconsistencies, requiring them to adapt, troubleshoot, and persist in the face of adversity.Overcoming these hurdles instills resilience and fortitude, attributes that are invaluable not only in academia but also in life.Moreover, the graduation project offers a platform for personal and intellectual growth. It provides students with the autonomy to explore topics of their interest, delveinto uncharted territories, and push the boundaries of knowledge. This journey of self-discovery not only enhances academic curiosity but also fosters a sense of ownership and accomplishment. Furthermore, presenting findings, defending arguments, and receiving feedback during project evaluations contribute to the development of presentation, communication, and critical evaluation skills, which are essential for academic and professional success.In conclusion, the graduation project is a cornerstone of academic development, offering students a unique opportunity to apply theoretical knowledge to real-world problems, fostering independent learning, interdisciplinary collaboration, resilience, and personal growth. By engaging in this endeavor, students not only demonstrate theiracademic prowess but also equip themselves with essential skills and attributes for future endeavors. Therefore, the graduation project stands as a testament to the culmination of academic journey and the beginning of a new chapter in students' intellectual and professional pursuits.。

办公楼毕业设计英文翻译(外文翻译)原文:The future of the tall buildingAnd structure of buildingsZoning effects on the density of tall buildings and solar design may raise ethical challenge.A combined project of old and new buildings may bring back human scale to our cities. Owners and conceptual designers will be challenged in the 1980s to produce economically sound, people-oriented buildings.In 1980 the Level House, designed by Skidmore, Owings and Merril1 (SOM) received the 25-year award from the American Institut e of Architects “in recognition of architectural design of enduring significance”. This award is given once a year for a building between 25and 35 years old .Lewis Mumford described the Lever House as “the first office building in which modern materials, m odern construction, modern functions have been combined with a modern plan”. At the time, this daring concept could only be achieved by visionary men like Gordon Bunshaft , the designer , and Charles Luckman , the owner and then-president of Lever Brothers . The project also included a few “first” : (1) it was the first sealed glass tower ever built ; (2) it was the first office building designed by SOM ;and (3) it was the first office building on Park Avenue to omit retail space on the first floor. Today, after hundreds of look-alike and variations on the grid design, we have reached what may be the epitome of tall building design: the nondescript building. Except for a few recently completed buildings that seem to be people-oriented in their lower floors, most tall buildings seem to be a repletion of the dull, graph-paper-like monoliths in many of our cities. Can this be the end of the design-line for tall buildings? Probably not. There are definite signs that are most encouraging. Architects and owners have recently begun to discuss the design problem publicly. Perhaps we are at the threshold of a new era. The 1980s may bring forth some new visionaries like Bunshaft and Luckman. If so, what kinds of restrictions or challenges do they face?译文:高层建筑展望及建筑结构区域规划对高层建筑物的密度和对自然采光设计可能引起道德问题将产生影响。

java毕业设计中英文翻译篇一:JAVA外文文献+翻译Java and the InternetIf Java is, in fact, yet another computer programming language, you may question why it is so important and why it is being promoted as a revolutionary step in computer programming. The answer isn’t immediately obvious if you’re coming from a traditional programming perspective. Although Java is very useful for solving traditional stand-alone programming problems, it is also important because it will solve programming problems on the World Wide Web.1. Client-side programmingThe Web’s initial server-browser design provided for interactive content, but the interactivity was completely provided by the server. The server produced static pages for the client browser, which would simply interpret and display them. Basic HTML contains simple mechanisms for data gathering: text-entry boxes, check boxes, radio boxes, lists and drop-down lists, as well as a button that can only be programmed to reset the data on the form or “submit” the data on the form backto the server. This submission passes through the Common Gateway Interface (CGI) provided on all Web servers. The text within the submission tells CGI what to do with it. The most common action is to run a program located on the server in a directory that’s typically called “cgi-bin.” (If you watch the address window at the top of your browser when you push a button on a Web page, you can sometimes see “cgi-bin” within all the gobbledygook there.) These programs can be written in most languages. Perl is a common choice because it is designed for text manipulation and is interpreted, so it can be installed on any server regardless of processor or operating system. Many powerful Web sites today are built strictly on CGI, and you can in fact do nearly anything with it. However, Web sites built on CGI programs can rapidly become overly complicated to maintain, and there is also the problem of response time. The response of a CGI program depends on how much data mustbe sent, as well as the load on both the server and the Internet. (On top of this, starting a CGI program tends to be slow.) The initial designers of the Web didnot foresee how rapidly this bandwidth would be exhausted for the kinds of applications people developed. For example, any sort of dynamic graphing is nearly impossible to perform with consistency because a GIF file must be created and moved from the server to the client for each version of the graph. And you’ve no doubt had direct experience with something as simple as validating the data on an input form. You press the submit button on a page; the data is shipped back to the server; the server starts a CGI program that discovers an error, formats an HTML page informing you of the error, and then sends the page back to you; you must then back up a page and try again. Not only is this slow, it’s inelegant.The solution is client-side programming. Most machines that run Web browsers are powerful engines capable of doing vast work, and with the original static HTML approach they are sitting there, just idly waiting for the server to dish up the next page. Client-side programming means that the Web browser is harnessed to do whatever work it can, and the result for the user is a much speedier and more interactive experience atyour Web site.The problem with discussions of client-side programming is that they aren’t very different from discussions of programming in general. The parameters are almost the same, but the platform is different: a Web browser is like a limited operating system. In the end, you must still program, and this accounts for the dizzying array of problems and solutions produced by client-side programming. The rest of this section provides an overview of the issues and approaches in client-side programming.2.Plug-insOne of the most significant steps forward in client-side programming is the development of the plug-in. This is a way for a programmer to add new functionality to the browser by downloading a piece of code that plugs itself into the appropriate spot in the browser. It tells the browser “from now on you can perform this new activity.” (You need to download the plug-in only once.) Some fast and powerful behavior is added to browsers via plug-ins, but writing a plug-in is not a trivial task, and isn’t something you’d wantto do as part of the process of building a particular site. The value of the plug-in for client-side programming is that it allows an expert programmer to develop a new language and add that language to a browser without the permission of the browser manufacturer. Thus, plug-ins provide a “back door”that allows the creation of new client-side programming languages (although not all languages are implemented as plug-ins).3.Scripting languagesPlug-ins resulted in an explosion of scripting languages. With a scripting language you embed the source code for your client-side program directly into the HTML page, and the plug-in that interprets that language is automatically activated while the HTML page is being displayed. Scripting languages tend to be reasonably easy to understand and, because they are simply text that is part of an HTML page, they load very quickly as part of the single server hit required to procure that page. The trade-off is that your code is exposed for everyone to see (and steal). Generally, however, you aren’t doing amazingly sophisticatedthings with scripting languages so this is not too much of a hardship.This points out that the scripting languages used inside Web browsers are really intended to solve specific types of problems, primarily the creation of richer and more interactive graphical user interfaces (GUIs). However, a scripting language might solve 80 percent of the problems encountered in client-side programming. Your problems might very well fit completely within that 80 percent, and since scripting languages can allow easier and faster development, you should probably consider a scripting language before looking at a more involved solution such as Java or ActiveX programming.The most commonly discussed browser scripting languages are JavaScript (which has nothing to do with Java; it’s named that way just to grab some of Java’s marketing momentum), VBScript (which looks like Visual Basic), andTcl/Tk, which comes from the popular cross-platform GUI-building language. There are others out there, and no doubt more in development.JavaScript is probably the most commonly supported. It comes built into both Netscape Navigator and the Microsoft Internet Explorer (IE). In addition, there are probably more JavaScript books available than there are for the other browser languages, and some tools automatically create pages using JavaScript. However, if you’re already fluent in Visual Basic or Tcl/Tk, you’ll be more productive using those scripting languages rather than learning a new one. (You’ll have your hands full dealing with the Web issues already.)4.JavaIf a scripting language can solve 80 percent of the client-side programming problems, what about the other 20 percent—the “really hard stuff?” The most popular solution today is Java. Not only is it a powerful programming language built to be secure, cross-platform, and international, but Java is being continually extended to provide language features and libraries that elegantly handle problems that are difficult in traditional programming languages, such as multithreading, database access, network programming, and distributed computing. Java allowsclient-side programming via the applet.An applet is a mini-program that will run only under a Web browser. The applet is downloaded automatically as part of a Web page (just as, for example, a graphic is automatically downloaded). When the applet is activated it executes a program. This is part of its beauty—it provides you with a way to automatically distribute the client software from the server at the time the user needs the client software, and no sooner. The user gets the latest version of the client software without fail and without difficult reinstallation. Because of the way Java is designed, the programmer needs to create only a single program, and that program automatically works with all computers that have browsers with built-in Java interpreters. (This safely includes the vast majority of machines.) Since Java is a full-fledged programming language, you can do as much work as possible on the client before and after making requests of theserver. For example, you won’t need to send a request form across the Internet to discover that you’ve gotten a date or some other parameter wrong, and yourclient computer can quickly do the work of plotting data instead of waiting for the server to make a plot and ship a graphic image back to you. Not only do you get the immediate win of speed and responsiveness, but the general network traffic and load on servers can be reduced, preventing the entire Internet from slowing down.One advantage a Java applet has over a scripted program is that it’s in compiled form, so the source code isn’t available to the client. On the other hand, a Java applet can be decompiled without too much trouble, but hiding your code is often not an important issue. Two other factors can be important. As you will see later in this book, a compiled Java applet can comprise many modules and take multiple server “hits” (accesses) to download. (In Java 1.1 and higher this is minimized by Java archives, called JAR files, that allow all the required modules to be packaged together and compressed for a single download.) A scripted program will just be integrated into the Web page as part of its text (and will generally be smaller and reduce server hits). This could be important to the responsiveness of your Website. Another factor is the all-important learning curve. Regardless of what you’ve heard, Java is not a trivial language to learn. If you’re a Visual Basic programmer, moving to VBScript will be your fastest solution, and since it will probably solve most typical client/server problems you might be hard pressed to justify learning Java. If you’re experienced with a scripting language you will certainly benefit from looking at JavaScript or VBScript before committing to Java, since they might fit your needs handily and you’ll be more productive sooner.to run its applets withi5.ActiveXTo some degree, the competitor to Java is Microsoft’s ActiveX, although it takes a completely different approach.

Bridge Waterway OpeningsIn a majority of cases the height and length of a bridge depend solely upon the amount of clear waterway opening that must be provided to accommodate the floodwaters of the stream. Actually, the problem goes beyond that of merely accommodating the floodwaters and requires prediction of the various magnitudes of floods for given time intervals. It would be impossible to state that some given magnitude is the maximum that will ever occur, and it is therefore impossible to design for the maximum, since it cannot be ascertained. It seems more logical to design for a predicted flood of some selected interval ---a flood magnitude that could reasonably be expected to occur once within a given number of years. For example, a bridge may be designed for a 50-year flood interval; that is, for a flood which is expected (according to the laws of probability) to occur on the average of one time in 50 years. Once this design flood frequency, or interval of expected occurrence, has been decided, the analysis to determine a magnitude is made. Whenever possible, this analysis is based upon gauged stream records. In areas and for streams where flood frequency and magnitude records are not available, an analysis can still be made. With data from gauged streams in the vicinity, regional flood frequencies can be worked out; with a correlation between the computed discharge for the ungauged stream and the regional flood frequency, a flood frequency curve can be computed for the stream in question. Highway CulvertsAny closed conduit used to conduct surface runoff from one side of a roadway to the other is referred to as a culvert. Culverts vary in size from large multiple installations used in lieu of a bridge to small circular or elliptical pipe, and their design varies in significance. Accepted practice treats conduits under the roadway as culverts. Although the unit cost of culverts is much less than that of bridges, they are far more numerous, normally averaging about eight to the mile, and represent a greater cost in highway. Statistics show that about 15 cents of the highway construction dollar goes to culverts, as compared with 10 cents for bridge. Culvert design then is equally as important as that of bridges or other phases of highway and should be treated accordingly.Municipal Storm DrainageIn urban and suburban areas, runoff waters are handled through a system of drainage structures referred to as storm sewers and their appurtenances. The drainage problem is increased in these areas primarily for two reasons: the impervious nature of the area creates a very high runoff; and there is little room for natural water courses. It is often necessary to collect the entire storm water into a system of pipes and transmit it over considerable distances before it can be loosed again as surface runoff. This collection and transmission further increase the problem, since all of the water must be collected with virtually no ponding, thus eliminating any natural storage; and though increased velocity the peak runoffs are reached more quickly. Also, the shorter times of peaks cause the system to be more sensitive to short-duration, high-intensity rainfall. Storm sewers, like culverts and bridges, are designed for storms of various intensity –return-period relationship, depending upon the economy and amount of ponding that can be tolerated.Airport DrainageThe problem of providing proper drainage facilities for airports is similar in many ways to that of highways and streets. However, because of the large and relatively flat surface involved the varying soil conditions, the absence of natural water courses and possible side ditches, and the greater concentration of discharge at the terminus of the construction area, some phases of the problem are more complex. For the average airport the overall area to be drained is relatively large and an extensive drainage system is required. The magnitude of such a system makes it even more imperative that sound engineeringprinciples based on all of the best available data be used to ensure the most economical design. Overdesign of facilities results in excessive money investment with no return, and underdesign can result in conditions hazardous to the air traffic using the airport.In other to ensure surfaces that are smooth, firm, stable, and reasonably free from flooding, it is necessary to provide a system which will do several things. It must collect and remove the surface water from the airport surface; intercept and remove surface water flowing toward the airport from adjacent areas; collect and remove any excessive subsurface water beneath the surface of the airport facilities and in many cases lower the ground-water table; and provide protection against erosion of the sloping areas. Ditches and Cut-slope DrainageA highway cross section normally includes one and often two ditches paralleling the roadway. Generally referred to as side ditches these serve to intercept the drainage from slopes and to conduct it to where it can be carried under the roadway or away from the highway section, depending upon the natural drainage. To a limited extent they also serve to conduct subsurface drainage from beneath the roadway to points where it can be carried away from the highway section.A second type of ditch, generally referred to as a crown ditch, is often used for the erosion protection of cut slopes. This ditch along the top of the cut slope serves to intercept surface runoff from the slopes above and conduct it to natural water courses on milder slopes, thus preventing the erosion that would be caused by permitting the runoff to spill down the cut faces.12 Construction techniquesThe decision of how a bridge should be built depends mainly on local conditions. These include cost of materials, available equipment, allowable construction time and environmental restriction. Since all these vary with location and time, the best construction technique for a given structure may also vary. Incremental launching or Push-out MethodIn this form of construction the deck is pushed across the span with hydraulic rams or winches. Decks of prestressed post-tensioned precast segments, steel or girders have been erected. Usually spans are limited to 50~60 m to avoid excessive deflection and cantilever stresses , although greater distances have been bridged by installing temporary support towers . Typically the method is most appropriate for long, multi-span bridges in the range 300 ~ 600 m ,but ,much shorter and longer bridges have been constructed . Unfortunately, this very economical mode of construction can only be applied when both the horizontal and vertical alignments of the deck are perfectly straight, or alternatively of constant radius. Where pushing involves a small downward grade (4% ~ 5%) then a braking system should be installed to prevent the deck slipping away uncontrolled and heavy bracing is then needed at the restraining piers.Bridge launching demands very careful surveying and setting out with continuous and precise checks made of deck deflections. A light aluminum or steel-launching nose forms the head of the deck to provide guidance over the pier. Special teflon or chrome-nickel steel plate bearings are used to reduce sliding friction to about 5% of the weight, thus slender piers would normally be supplemented with braced columns to avoid cracking and other damage. These columns would generally also support the temporary friction bearings and help steer the nose.In the case of precast construction, ideally segments should be cast on beds near the abutments and transferred by rail to the post-tensioning bed, the actual transport distance obviously being kept to the minimum. Usually a segment is cast against the face of the previously concerted unit to ensure a good fit when finally glued in place with an epoxy resin. If this procedure is not adopted , gaps of approximately 500mm shold be left between segments with the reinforcements running through andstressed together to form a complete unit , but when access or space on the embankment is at a premium it may be necessary to launch the deck intermittently to allow sections to be added progressively .The correponding prestressing arrangements , both for the temporary and permanent conditions would be more complicated and careful calculations needed at all positions .The pricipal advantage of the bridge-launching technique is the saving in falsework, especially for high decks. Segments can also be fabricated or precast in a protected environment using highly productive equipment. For concrete segment, typically two segment are laid each week (usually 10 ~ 30 m in length and perhaps 300 to 400 tonnes in weight) and after posttensioning incrementally launched at about 20 m per day depending upon the winching/jacking equipment.Balanced Cantiulever ConstructionDevelopment in box section and prestressed concrete led to short segment being assembled or cast in place on falsework to form a beam of full roadway width. Subsequently the method was refined virtually to eliminate the falsework by using a previously constructed section of the beam to provide the fixing for a subsequently cantilevered section. The principle is demonsrated step-by-step in the example shown in Fig.1.In the simple case illustrated, the bridge consists of three spans in the ratio 1:1:2. First the abutments and piers are constructed independently from the bridge superstructure. The segment immediately above each pier is then either cast in situ or placed as a precast unit .The deck is subsequently formed by adding sections symmetrically either side.Ideally sections either side should be placed simultaneously but this is usually impracticable and some inbalance will result from the extra segment weight, wind forces, construction plant and material. When the cantilever has reached both the abutment and centre span,work can begin from the other pier , and the remainder of the deck completed in a similar manner . Finally the two individual cantilevers are linked at the centre by a key segment to form a single span. The key is normally cast in situ.The procedure initially requires the first sections above the column and perhaps one or two each side to be erected conventionally either in situ concrete or precast and temporarily supported while steel tendons are threaded and post-tensioned . Subsequent pairs of section are added and held in place by post-tensioning followed by grouting of the ducts. During this phase only the cantilever tendons in the upper flange and webs are tensioned. Continuity tendons are stressed after the key section has been cast in place. The final gap left between the two half spans should be wide enough to enable the jacking equipment to be inserted. When the individual cantilevers are completed and the key section inserted the continuity tendons are anchored symmetrically about the centre of the span and serve to resist superimposed loads, live loads, redistribution of dead loads and cantilever prestressing forces.The earlier bridges were designed on the free cantilever principle with an expansion joint incorporated at the center .Unfortunately,settlements , deformations , concrete creep and prestress relaxation tended to produce deflection in each half span , disfiguring the general appearance of the bridge and causing discomfort to drivers .These effects coupled with the difficulties in designing a suitable joint led designers to choose a continuous connection, resulting in a more uniform distribution of the loads and reduced deflection. The natural movements were provided for at the bridge abutments using sliding bearings or in the case of long multi-span bridges, joints at about 500 m centres.Special Requirements in Advanced Construction TechniquesThere are three important areas that the engineering and construction team has to consider:(1) Stress analysis during construction: Because the loadings and support conditions of the bridge are different from the finished bridge, stresses in each construction stage must be calculated to ensurethe safety of the structure .For this purpose, realistic construction loads must be used and site personnel must be informed on all the loading limitations. Wind and temperature are usually significant for construction stage.(2) Camber: In order to obtain a bridge with the right elevation, the required camber of the bridge at each construction stage must be calculated. It is required that due consideration be given to creep and shrinkage of the concrete. This kind of the concrete. This kind of calculation, although cumbersome, has been simplified by the use of the compiters.(3) Quality control: This is important for any method construction, but it is more so for the complicated construction techniques. Curing of concrete, post-tensioning, joint preparation, etc. are detrimental to a successful structure. The site personnel must be made aware of the minimum concrete strengths required for post-tensioning, form removal, falsework removal, launching and other steps of operations.Generally speaking, these advanced construction techniques require more engineering work than the conventional falsework type construction, but the saving could be significant.大桥涵洞在大多数情况中桥梁的高度和跨度完全取决于河流的流量,桥梁的高度和跨度必须能够容纳最大洪水量.事实上,这不仅仅是洪水最大流量的问题,还需要在不同时间间隔预测不同程度的水灾。

附件1:外文资料翻译译文网络编程历史上的网络编程都倾向于困难、复杂,而且极易出错。

程序员必须掌握与网络有关的大量细节,有时甚至要对硬件有深刻的认识。

一般地,我们需要理解连网协议中不同的“层”(Layer)。

而且对于每个连网库,一般都包含了数量众多的函数,分别涉及信息块的连接、打包和拆包;这些块的来回运输;以及握手等等。

这是一项令人痛苦的工作。

但是,连网本身的概念并不是很难。

我们想获得位于其他地方某台机器上的信息,并把它们移到这儿;或者相反。

这与读写文件非常相似,只是文件存在于远程机器上,而且远程机器有权决定如何处理我们请求或者发送的数据。

Java最出色的一个地方就是它的“无痛苦连网”概念。

有关连网的基层细节已被尽可能地提取出去,并隐藏在JVM以及Java的本机安装系统里进行控制。

我们使用的编程模型是一个文件的模型;事实上,网络连接(一个“套接字”)已被封装到系统对象里,所以可象对其他数据流那样采用同样的方法调用。

除此以外,在我们处理另一个连网问题——同时控制多个网络连接——的时候,Java内建的多线程机制也是十分方便的。

本章将用一系列易懂的例子解释Java的连网支持。

早期网络只解决了如何在本地网络环境中为机器提供唯一的名字。

但Java面向的是整个因特网,这要求用一种机制对来自世界各地的机器进行标识。

为达到这个目的,我们采用了IP(互联网地址)的概念。

毕业设计论文化学系毕业论文外文文献翻译中英文英文文献及翻译A chemical compound that is contained in the hands of the problemsfor exampleCatalytic asymmetric carbon-carbon bond formation is one of the most active research areas in organic synthesis In this field the application of chiral ligands in enantioselective addition of diethylzinc to aldehydes has attracted much attention lots of ligands such as chiral amino alcohols amino thiols piperazines quaternary ammonium salts 12-diols oxazaborolidines and transition metal complex with chiral ligands have been empolyed in the asymmetric addition of diethylzinc to aldehydes In this dissertation we report some new chiral ligands and their application in enantioselective addition of diethylzinc to aldehydes1 Synthesis and application of chiral ligands containing sulfur atomSeveral a-hydroxy acids were prepared using the literature method with modifications from the corresponding amino acids valine leucine and phenylalanine Improved yields were obtained by slowly simultaneous addition of three fold excess of sodium nitrite and 1 tnolL H2SO4 In the preparation of a-hydroxy acid methyl esters from a-hydroxy acids following the procedure described by Vigneron a low yield 45 was obtained It was found that much better results yield 82 couldbe obtained by esterifying a-hydroxy acids with methanol-thionyl chlorideThe first attempt to convert S -2-hydroxy-3-methylbutanoic acid methyl ester to the corresponding R-11-diphenyl-2-mercapto-3-methyl-l-butanol is as the following S-2-Hydroxy-3-methylbutanoic acid methyl ester was treated with excess of phenylmagnesium bromide to give S -11-diphenyl-3-methyl-12-butanediol which was then mesylated to obtain S -11-diphenyl-3-methyl-2-methanesulfonyloxy -l-butanol Unfortunately conversion of S-11-diphenyl-3-methyl-2- methanesulfonyloxy -l-butanol to the corresponding thioester by reacting with potassium thioacetate under Sn2 reaction conditions can be achieved neither in DMF at 20-60 nor in refluxing toluene in the presence of 18-crown-6 as catalyst When S -1ll-diphenyl-3-methyl-2- methane sulfonyloxy -l-butanol was refluxed with thioacetic acid in pyridine an optical active epoxide R-22-diphenyl -3-isopropyloxirane was obtained Then we tried to convert S -11-diphenyl-3-methyl-l2-butanediol to the thioester by reacting with PPh3 DEAD and thioacetic acid the Mitsunobu reaction but we failed either probably due to the steric hindrance around the reaction centerThe actually successful synthesis is as described below a-hydroxy acid methyl esters was mesylated and treated with KSCOCH3 in DMF to give thioester this was than treated with phenyl magnesium bromide to gave the target compound B-mercaptoalcohols The enantiomeric excesses ofp-mercaptoalcohols can be determined by 1H NMR as their S -mandeloyl derivatives S -2-amino-3-phenylpropane-l-thiol hydrochloride was synthesized from L-Phenylalanine L-Phenylalanine was reduced to the amino alcohol S -2-amino-3-phenylpropanol Protection of the amino group using tert-butyl pyrocarbonate gave S -2-tert-butoxycarbonylamino-3-phenylpropane-l-ol which was then O-mesylated to give S -2-tert-butoxycarbonylamino-3-phenylpropyl methanesulfonate The mesylate was treated with potassium thioacetate in DMF to give l-acetylthio-2-tert-butoxycarbonylamino-3-phenylpropane The acetyl group was then removed by treating with ammonia in alcohol to gave S -2-tert-butoxycarbonylamino-3-phenyl-propane-l-thiol which was then deprotected with hydrochloric acid to give the desired S-2-amino-3-phenylpropane-1-thiol hydrochlorideThe enantioselective addition of diethylzinc to aldehydes promoted by these sulfur containing chiral ligands produce secondary alcohols in 65-79 Synthesis and application of chiral aminophenolsThree substituted prolinols were prepared from the naturally-occurring L-proline using reported method with modifications And the chiral aminophenols were obtained by heating these prolinols with excess of salicylaldehyde in benzene at refluxThe results of enantioselective adBelow us an illustration forexampleN-Heterocyclic carbenes and L-Azetidine-2-carboxylicacidN-Heterocyclic carbenesN-Heterocyclic carbenes have becomeuniversal ligands in organometallic and inorganic coordination chemistry They not only bind to any transition metal with low or high oxidation states but also to main group elements such as beryllium sulfur and iodine Because of their specific coordination chemistry N-heterocyclic carbenes both stabilize and activate metal centers in quite different key catalytic steps of organic syntheses for example C-H activation C-C C-H C-O and C-N bond formation There is now ample evidence that in the new generation of organometallic catalysts the established ligand class of organophosphanes will be supplemented and in part replaced byN-heterocyclic carbenes Over the past few years this chemistry has become the field of vivid scientific competition and yielded previously unexpected successes in key areas of homogeneous catalysis From the work in numerous academic laboratories and in industry a revolutionary turningpoint in oraganometallic catalysis is emergingIn this thesis Palladium Ⅱ acetate and NN"-bis- 26-diisopropylphenyl dihydro- imidazolium chloride 1 2 mol were used to catalyze the carbonylative coupling of aryl diazonium tetrafluoroborate salts and aryl boronic acids to form aryl ketones Optimal conditions include carbon monoxide 1 atm in 14-dioxane at 100℃ for 5 h Yields for unsymmetrical aryl ketones ranged from 76 to 90 for isolated materials with only minor amounts of biaryl coupling product observed 2-12 THF as solvent gave mixtures of products 14-Dioxane proved to be the superior solvent giving higher yieldsof ketone product together with less biphenyl formation At room temperature and at 0℃ with 1 atm CO biphenyl became the major product Electron-rich diazonium ion substrates gave a reduced yield with increased production of biaryl product Electron-deficient diazonium ions were even better forming ketones in higher yields with less biaryl by-product formed 2-Naphthyldiazonium salt also proved to be an effective substrate givingketones in the excellent range Base on above palladium NHC catalysts aryl diazonium tetrafluoroborates have been coupled with arylboron compounds carbon monoxide and ammonia to give aryl amides in high yields A saturated yV-heterocyclic carbene NHC ligand H2lPr 1 was used with palladium II acetate to give the active catalyst The optimal conditions with 2mol palladium-NHC catalyst were applied with various organoboron compounds and three aryl diazonium tetrafluoroborates to give numerous aryl amides in high yield using pressurized CO in a THF solution saturated with ammonia Factors that affect the distribution of the reaction products have been identified and a mechanism is proposed for this novel four-component coupling reactionNHC-metal complexes are commonly formed from an imidazolium salt using strong base Deprotonation occurs at C2 to give a stable carbene that adds to form a a-complex with the metal Crystals were obtained from the reaction of imidazolium chloride with sodium t- butoxide Nal and palladium II acetate giving a dimeric palladium II iodide NHC complex The structure adopts a flat 4-memberedring u2 -bridged arrangement as seen in a related dehydro NHC complex formed with base We were pleased to find that chloride treated with palladium II acetate without adding base or halide in THF also produced suitable crystals for X-ray anaysis In contrast to the diiodide the palladium-carbenes are now twisted out of plane adopting a non-planar 4-ring core The borylation of aryldiazonium tetrafluoroborates with bis pinacolatoborane was optimized using various NHC ligand complexes formed in situ without adding base NN"-Bis 26-diisopropylphenyl-45-dihydroimidazolium 1 used with palladium acetate in THF proved optimal giving borylated product in 79 isolated yield without forming of bi-aryl side product With K2CO3 and ligand 1 a significant amount of biaryl product 24 was again seen The characterization of the palladium chloride complex by X-ray chrastallography deL-Azetidine-2-carboxylic acidL-Azetidine-2-carboxylic acid also named S -Azetidine-2-carboxylic acid commonly named L-Aze was first isolated in 1955 by Fowden from Convallaria majalis and was the first known example of naturally occurring azetidine As a constrained amino acid S -Azetidine-2-carboxylic acid has found many applications in the modification of peptides conformations and in the area of asymmetric synthesis which include its use in the asymmetric reduction of ketones Michael additions cyclopropanations and Diels-Alder reactions In this dissertation five ways for synthesize S-Azetidine-2-carboxylic acid were studied After comparing all methods theway using L-Aspartic acid as original material for synthesize S-Azetidine-2-carboxylic acid was considered more feasible All mechanisms of the way"s reaction have also been studied At last the application and foreground of S -Azetidine-2-carboxylic acid were viewed The structures of the synthetic products were characterized by ThermalGravity-Differential Thermal Analysis TG-DTA Infrared Spectroscopy IR Mass Spectra MS and 1H Nuclear Magnetic Resonance 1H-NMR Results showed that the structures and performances of the products conformed to the anticipation the yield of each reaction was more than 70 These can conclude that the way using L-Aspartie acid as original material for synthesize S -Azetidine-2-carboxylic acid is practical and

自由现金流代理成本有显着的影响。

在这两个领域相结合的研究,将有助于建立和扩大理论体系。

代理成本理论基础上,本研究首先分类自由现金流以及统计方法的特点。

此外,投资自由现金流代理成本的存在证明了模型。

自由现金流代理成本理论引入限制,分析表明,它会改变代理成本,进而将影响代理成本和资本结构之间的关系,最后,都会影响到最优资本结构点,以保持平衡。

具体地说,自由现金流增加,相应地,债务比例会降低。

关键词:资本结构,现金流,代理成本,非金钱利益1、介绍代理成本理论,金融契约理论,信号模型和新的啄食顺序理论,新的资本结构理论的主要分支。

财务con-道的理论侧重于限制股东的合同行为,解决股东和债权人之间的冲突。

信令模式和新的啄食顺序理论中心解决投资者和管理者之间的冲突。

这两种类型的冲突是在商业组织中的主要冲突。

代理成本理论认为,如何达到平衡这两种类型的冲突,资本结构是如何形成的,这是比前两次在一定程度上更多的理论更全面。

……Agency Cost under the Restriction of Free Cash FlowAbstractAgency cost theory is an important branch of capital structural theory. Free cash flow has significant impact on agency cost. The combination of research on these two fields would help to build and extend the theoretical system. Based on agency cost theory, the present study firstly categorized the characteristics of free cash flow as well as the statistical methodologies. Furthermore, the existence of investing free cash flow in agency cost was proved by a model. Then free cash flow was introduced into agency cost theory as restriction, the analysis shows that it will change agency cost, in turn, will have an impact on the relationship between agency cost and capital structure, finally, will influence the optimal capital structure point to maintain the equilibrium. Concretely, with the increasing free cash flow, correspondingly, debt proportion will decrease.Keywords:Capital Structure,Free Cash Flow,Agency Cost,Non-Pecuniary Benefit1. IntroductionAgency cost theory, financial contract theory, signaling model and new pecking order theory are the main branches of new capital structure theory. Financial con-tract theory focuses on restricting stockholders’ behavior by contract and solving the conflict between stockholders and creditors. Signaling model and new pecking order theory center on solving the conflict between investors and managers. These two types of conflict are the main conflict in business organizations. Agency cost theory considers how equilibrium is reached in both types of conflict and how capital structure is formed, which is more theory is more comprehensive than the previous two to some degree.……。

毕业设计英文资料翻译Translation of the English Documents for Graduation Design课题名称院(系)专业姓名学号起讫日期指导教师2011 年 02 月 20 日译文:室内设计室内设计不仅包括装修及家具的空间,而且还考虑到空间规划,灯光,与用户行为有关的程序化问题,包括从具体问题的可及性到在空间中的活动的性质。

在商业和公共空间显著的变化后,室内设计如今的标志是一个新的弹性类型学。

室内设计不仅包括方案规划也包括室内空间的物理治疗:预测其使用的性质以及它的家具和表面,包括墙,地面,天花板。

在职权范围上,室内设计有别于室内装修工程。

装修关心的是家具的选择,然而设计者要把离散的装饰元素整合成方案关注的空间和使用。

室内设计师在从底层向上的内部的空间时间方面与与建筑师合作,但是他们仍然独立的工作,尤其在翻修的情况下。

历史上,植根于总体艺术作品的概念,曾经都是建筑师设计的。

总体艺术作品的概念源于十九世纪末和二十世纪初的工艺美术运动。

其支持者(从弗兰克·劳埃德·赖特到凡德罗)在室内设计专业的起源期间延长其做法以包括内饰领域行为并不是偶然的。

事实上,这是一个建筑师采取的防御措施,建筑师们把室内装修或设计师的形式上的干预看作是对他们完整的艺术性的一种威胁。

如今,除了像理查德·迈耶那样的非常重视均匀性的现代主义者,扮演室内设计师角色的建筑师(数量在增长)更有倾向于理论与实践的折衷,并联21世纪的定价多元化。

尽管如此,对室内设计师以及室内设计领域的偏见持续存在。

由于室内被视为一个集装箱的蜉蝣,从而阻碍了对室内的批评性的讨论。

此外,对室内的传统观点充满了偏见:阶级偏见与百年历史的协会商人有关,性别偏见与把装饰行业描述成主要是妇女和男性同性恋的领域。

因此,室内设计作为文化价值的表达的信誉已被严重损坏。

然而,对文化大系统的理解在全球化的影响下一直在变化。

在一个更宽容的环境中,鼓励不同文化间的融合,高文化和低文化的区别被消除。

同样,有更频繁的生产性借贷的事例发生在建筑,设计,装修等曾经被看作是专有领地的领域。

并且建筑,室内设计,室内装修领域仍然有不同的教育协议以及不同的关注重点,他们表现出更大的互相的兴趣。

另一种考虑这种新兴的合成的方法是用现代,技术和历史替代建筑,室内设计和装修的三合一。

后现代时代的特征之一是提高了对过去影响现在的角色的认识。

在室内,这表现在一个新的兴趣饰品,工艺和重要性以及空间复杂性,所有平行于正在运行的现代化的项目。

更重要的是,有一种新的弹性类型学。

如今,传统的室内类型例如房子,仓库,办公室,餐厅等,尽力控制它们的边界。

方案收敛的表现能在公共场合以及商业空间被清晰的发现,渴望更加界面友好和有消费意识。

越来越多的私立医院(竞争患者)雇用设施并形成灵感来自豪华温泉的语言;同时,许多体育馆以及健身俱乐部采用临床医疗设施以向客户介绍自己服务的价值。

同样的室内协议能够在办公室中发现,指派非正式的,现场工作理论的艺术家的仓库。

在旅馆使用美术馆的语言。

相似的,越来越多的杂货店和书店包括用于饮食和交际的空间以及家具。

同时,有一种新的舒适的在室内风格上趋同,从设计的历史上私有和重组不同的报价。

这些室内布局是艺术的混合,它们不是简单的混合以及匹配家具和风格,而是通过当代的镜头进行过滤。

现代室内布局的另一个标志是叙事的公开结合。

在零售空间坚持严格的环境主题,例如拉尔夫·劳伦服装店和像拉斯维加斯的赌场那样的娱乐场所。

然而,更好玩的小线性办法说明越来越普遍。

在所有的室内类型学中,住宅已经被改变所轻微的影响,除了短暂的趋势,如室外厨房和浴室的魅力。

然而,住宅设计占据室内设计全面的主导地位。

它已经成为反思的催化剂,使得一系列空间坚定的从中分离出来,从秘书室到护士站再到图书馆的阅览室。

办公室的个人住宿的考虑,医院色彩的使用,图书馆提供沙发正变的很平常,仅仅引用这三个例子。

这种环境(与窗帘,壁纸,除其他住宅要素)为以前的地域提供了更多的舒适性,安心,愉悦,而这是以前惯例所禁止和社会所排除的。

毫无疑问的,这些公共领域以及商业空间的变化是由20世纪60年代的解放运动带来的。

这些运动反对种族,阶级,性别的障碍,以及作为更大气候以及好客和住宿基础的身体能力。

在流行的住宅模式中发现一个完全不同的议程也是可能的。

把国内设施投入到商业空间,例如办公室室内的娱乐空间也可以解释为一个更广泛的尝试的一部分,尝试把更容易既接受的氛围引入自由资本主义市场。

从这点上来看,室内设计肩负着娱乐的任务,没有什么新的把戏。

每一个室内布局都是舞台设置的基础。

它也不是特别隐匿-只要自负是透明的。

然而,当幻想变成妄想,也就是当为疾病的现实而设计补偿过度时,或者当由于全天候经济的无情的要求使得办公室变成代理人的公寓时,这是危险的表现。

在这些情况下,设计放弃其潜力改变日常生活,金额略多于一个浅显的重新命名空间。

另外一种力量正在推动室内设计的演化,扩大公众对设计以及设计师的认识。

设计作为市容和地位的象征的需求在逐渐增长,受住房杂志扩散的影响,电视节目专门讨论家庭装饰以及广告系列的商业实体,例如塔吉特和宜家家居。

在西方,繁荣再加上媒体的胃口,已经全部迷恋室内设计,也反映了自恋的消费推动型社会。

一方面,越来越多的公众形象设计产生出的有正面的民主的成果,这些设计能够在DIY网络站点上看到,并且像家庭百货那样的企业强调自力更生。

这也可以更普遍的认为重新审议美中隐含的定价设计是一种社会现象,由其倾向去激励情况有所改善。

另一方面,室内设计的通过人物例如菲利普斯塔克,玛莎斯图尔特和芭芭拉巴里的流行已经鼓励肤浅理解内部的注意力更多地集中在物体而不是对行为和相互作用的对象。

在室内设计方面,所有最近的爆炸事件,仍然存在根本的保守的舞台设计,因为它是根深蒂固的安全性与舒适性的观念中。

这种看法由于特殊行动而加剧了,例如,医疗和盛情款待。

虽然这些企业了深入了解心理学,力学和经济学知识的特殊环境,但是它们还长期区别阻碍更有机结合的办法,内部的延伸架构,甚至外面的风景。

一个显著的例外是设计和建筑公司的增加,增加了的支撑材料以及其在室内应用方面的专门的技术。

同时,设计公司用持久性标识自己,并提升自己为环保主义者。

一场用行动承担环境责任的活动正在开展。

在过去的四十年间,人们努力使室内设计领域专业化并给予它与建筑平等的地位。

在美国和加拿大,室内教育学会以前叫做教育研究基金会,讨论在学院以及大学里的室内设计教育以形成实践的标准。

此外,国际工业设计会议把室内设计包含在其范围内,把它定义为是“智力性的专业,而非仅仅是交易或者一种娱乐服务”的一部分。

然而,室内设计人员的教育仍然随着无标准教育而存在惊人的变数。

因此,室内设计仍然被认为是对专家和业余人员都开放的领域。

这种观念的形成和这个领域较短的历史以及更广阔的文化外力相互包含相互作用导致的全球化有关。

原文:Interior DesignSusan YelavichInterior design embraces not only the decoration and furnishing of space, but also considerations of space planning, lighting, and programmatic issues pertaining to user behaviors, ranging from specific issues of accessibility to the nature of the activities to be conducted in the space. The hallmark of interior design today is a new elasticity in typologies, seen most dramatically in the domestication of commercial and public spaces.Interior design encompasses both the programmatic planning and physical treatment of interior space: the projection of its use and the nature of its furnishings and surfaces, that is, walls, floors, and ceilings. Interior design is distinguished from interior decoration in the scope of its purview. Decorators are primarily concerned with the selection of furnishings, while designers integrate the discrete elements of décor into programmatic concerns of space and use. Interior designers generally practice collaboratively with architects on the interiors of spaces built from the ground up, but they also work independently, particularly in the case of renovations. There is also a strong history of architect-designed interiors, rooted in the concept of Gesamtkunstwerk, the total work of art, that came out of the Arts & Crafts movement of the late nineteenth and early twentieth century. It is no accident that its strongest proponents (from Frank Lloyd Wright to Mies van der Rohe) extended their practices to include the realm of interiors during the nascency of the interior-design profession. Indeed, it was a defensive measure taken by architects who viewed formal intervention by an interior decorator or designer as a threat to the integrity of their aesthetic.Today, apart from strict modernists like Richard Meier who place a premium on homogeneity, architects who take on the role of interior designer (and their numbers are growing) are more likely to be eclectic in philosophy and practice, paralleling the twenty-firstcentury's valorization of plurality. Nonetheless, the bias against interior designers and the realm of the interior itself continues to persist. Critical discussions of the interior have been hampered by its popular perception as a container of ephemera. Furthermore, conventional views of the interior have been fraught with biases: class biases related to centuries-old associations with tradesmen and gender biases related to the depiction of the decorating profession as primarily the domain of women and gay men. As a result, the credibility of the interior as an expressionof cultural values has been seriously impaired.However, the conditions and the light in which culture-at-large is understood are changing under the impact of globalization. The distinctions between “high” culture and “low” culture are dissipating in a more tolerant climate that encourages the cross-fertilization between the two poles. Likewise, there are more frequent instances of productive borrowings among architecture, design, and decoration, once considered exclusive domains. And while the fields of architecture, interior design, and interior decoration still have different educational protocols and different concentrations of emphasis, they are showing a greater mutuality of interest.Another way to think of this emergent synthesis is to substitute the triad of “architecture, interior design, and decoration” with “modernity, technology, and history.” One of the hallmarks of the postmodern era is a heightened awareness of the role of the past in shaping the present. In the interior, this manifests itself in a renewed interest in ornament, in evidence of craft and materiality, and in spatial complexities, all running parallel to the ongoing project of modernity.Even more significantly, there is a new elasticity in typologies. Today, the traditional typologies of the interior—house, loft, office, restaurant, and so on—strain to control their borders. Evidence of programmatic convergences can clearly be seen in public and commercial spaces that aspire to be both more user-friendly and consumer-conscious. Growing numbers of private hospitals (in competition for patients) employ amenities and form languages inspired by luxury spas; at the same time, many gyms and health clubs are adopting the clinical mien of medical facilities to convince their clients of the value of their services. The same relaxation of interior protocols can be seen in offices that co-opt the informal, live-work ethic of the artist's loft, and in hotels that use the language (and contents) of galleries. Similarly, increasing numbers of grocery stores and bookstores include spaces and furniture for eating andsocializing.Likewise, there is a new comfort with stylistic convergences in interiors that appropriate and recombine disparate quotations from design history. These are exemplified in spaces such as Rem Koolhaas' Casa da Musica (2005) in Porto, Portugal (with its inventive use of traditional Portuguese tiles), and Herzog & de Meuron's Walker Art Center (2005) in Minneapolis, Minnesota (where stylized acanthus-leaf patterns are used to mark gallery entrances). These interiors make an art out of hybridism. They do not simply mix and match period furnishings and styles, but refilter them through a contemporary lens.Another hallmark of the contemporary interior is the overt incorporation of narrative. Tightly themed environments persist in retail spaces such as Ralph Lauren's clothing stores and in entertainment spaces like Las Vegas casinos. However, a more playful and less linear approach to narrative is increasingly common.Of all the typologies of the interior, the residence has been least affected by change, apart from ephemeral trends such as outdoor kitchens and palatial bathrooms. However, the narrative of the residence dominates interior design at large. It has become the catalyst for rethinking a host of spaces once firmly isolated from it, ranging from the secretary's cubicle, to the nurse's station, to the librarian's reading room. Considerations such as the accommodation of personal accessories in the work space, the use of color in hospitals, and the provision of couches in libraries are increasingly common, to cite just three examples. The domestication of such environments (with curtains and wallpaper, among other residential elements) provides more comfort, more reassurance, and more pleasure to domains formerly defined by institutional prohibitions and social exclusions. Unquestionably, these changes in public and commercial spaces are indebted to the liberation movements of the late 1960s. The battles fought against barriers of race, class, gender, and physical ability laid the groundwork for a larger climate of hospitality and accommodation.It is also possible to detect a wholly other agenda in the popularity of the residential model. The introduction of domestic amenities into commercial spaces, such as recreation spaces in office interiors, can also be construed as part of a wider attempt to put a more acceptable face on the workings of free-market capitalism. In this view, interior design dons the mask of entertainment. There is nothing new about the charade. Every interior is fundamentally a stageset. Nor is it particularly insidious—as long as the conceit is transparent. Danger surfaces, however, when illusion becomes delusion—when design overcompensates for the realities of illness with patronizing sentiment, or when offices become surrogate apartments because of the relentless demands of a round-the-clock economy. In these instances, design relinquishes its potential to transform daily life in favor of what amounts to little more than a facile re-branding of space.Another force is driving the domestication of the interior and that is the enlarged public awareness of design and designers. There is a growing popular demand for design as amenity and status symbol, stimulated by the proliferation of shelter magazines, television shows devoted to home decorating, and the advertising campaigns of commercial entities such as Target and Ikea. In the Western world, prosperity, combined with the appetite of the media, has all but fetishized the interior, yielding yet another reflection of the narcissism of aconsumer-driven society. On the one hand, there are positive, democratic outcomes of the growing public profile of design that can be seen in the rise of do-it-yourself web sites and enterprises like Home Depot that emphasize self-reliance. It can also be argued, more generally, that the reconsideration of beauty implicit in the valorization of design is an ameliorating social phenomenon by virtue of its propensity to inspire improvement. On the other hand, the popularization of interior design through personas such as Philippe Starck, Martha Stewart, and Barbara Barry has encouraged a superficial understanding of the interior that is more focused on objects than it is on behaviors and interactions among objects.For all the recent explosion of interest in interior design, it remains, however, a fundamentally conservative arena of design, rooted as it is in notions of enclosure, security, and comfort. This perception has been exacerbated by the growth of specialized practices focused, for example, on healthcare and hospitality. While such firms offer deep knowledge of the psychology, mechanics, and economies of particular environments, they also perpetuate distinctions that hinder a more integral approach to the interior as an extension of architecture and even the landscape outside. One notable exception is the growth of design and architecture firms accruing expertise in sustainable materials and their applications to the interior. At the same time that design firms are identifying themselves with sustainability and promoting themselves as environmentalists, a movement is building to incorporate environmentalresponsibility within normative practice.Over the past four decades, efforts have intensified to professionalize the field of interior design and to accord it a status equal to that of architecture. In the US and Canada the Council for Interior Design Accreditation, formerly known as FIDER, reviews interior design education programs at colleges and universities to regulate standards of practice. Furthermore, the International Council of Societies of Industrial Design (ICSID) embraces interior design within its purview, defining it as part of “intelle ctual profession, and not simply a trade or a service for enterprises.”Yet, the education of interior designers remains tremendously variable, with no uniformity of pedagogy. Hence, interior design continues to be perceived as an arena open to the specialist and the amateur. This perception is indicative of both the relatively short history of the profession itself and the broader cultural forces of inclusion and interactivity that mark a global society.原文来源:Board of International Research in Design,Design Dictionary Perspectives on Design Terminology,Birkhäuser V erlag AG 2008。
