附录附录A 外文翻译第一部分英文原文4.2.2 Model that Failed in Punching ShearIt was realized that complete restraint in both the longitudinal and transversedirections is necessary for the development of the internal arching system in the deck slab. With this realization,another half-scale model of a two-girder bridge was built. This model also had a deck slab reinforced only by polypropylene fibres, and was very similar to the previous one, the main difference being that the top flangesof the girders were now interconnected by transverse steel straps lying outside the deck slab. A view of the steel work of this model can be seen in Fig. 4.7.These straps were provided so as to serve as transverse ties to the internal arch in the slab.The 100 mm thick slab of the model with transverse straps failed under a central load of 418 kN in a punching-shear failure mode. As can be seen in Fig. 4.8, the damaged area of the slab was highly localized. It can be appreciated that with such a high failure load, the thin deck slab of the half-scale model could have easily withstood the weights of even the heaviest wheel load of commercial vehicles.The model tests described above and in sub-section 4.2.1 clearly demonstrate that an internal arching action will indeed develop in a deck slab, but only if it is suitably restrained.4.2.3 Edge StiffeningA further appreciation of the deck slab arching action is provided by tests on a scale model of a skew slab-on-girder bridge. As will be discussed in sub-section 4.4.2, one transverse free edge of the deck slab of this model was stiffened by a composite steel channel with its web in the vertical plane. The other free edge was stiffened by a steel channel diaphragm with its web horizontal and connected to the deck slab through shear connectors. The deck slab near the former transverse edge failed in a mode that was a hybrid between punching shear and flexure. Tests near the composite diaphragm led to failure at a much higher load in punching shear (Bakht and Agarwal, 1993).The above tests confirmed yet again that the presence of the internal arching action in deck slabs induces high in-plane force effects which in turn demand stiffer restraint in the plane of the deck than in the out-of-plane direction.4.3 INTERNALLY RESTRAINED DECK SLABSDeck slabs which require embedded reinforcement for strength will now be referred to as internally restrained deck slabs. The state-of-art up to 1986 relating to the quantification and utilization of the beneficial internal arching action in deck slabs with steel reinforcement has been provided by Bakht and Markovic (1986). Their conclusions complemented with up-to-date information are presented in this chapter in a generally chronological order which, however, cannot be adhered to rigidlybecause of the simultaneous occurrence of some developments.4.3.1 Static Tests on Scale ModelsAbout three decades ago, the Structures Research Office of the Ministry of Transportation of Ontario (MTO), Canada, sponsored an extensive laboratory-based research program into the load carrying capacity of deck slabs; this research program was carried out at Queen's University, Kingston, Ontario. Most of this research was conducted through static tests on scale models of slab-on-girder bridges. This pioneering work is reported by Hewitt and Batchelor (1975) and later by Batchelor et al. (1985), and is summarized in the following.The inability of the concrete to sustain tensile strains, which leads to cracking, has been shown to be the main attribute which causes the compressive membrane forces to develop. This phenomenon is illustrated in Fig. 4.9 (a) which shows the part cross-section of slab-on-girder bridge under the action of a concentrated load.The cracking of the concrete, as shown in the figure, results in a net compressive force near the bottom face of the slab at each of the two girder locations. Midway between the girders, the net compressive force moves towards the top of the slab. It can be readily visualized that the transition of the net compressive force from near the top in the middle region, to near the bottom at the supports corresponds to the familiar arching action. Because of this internal arching action, the failure mode of a deck slab under a concentrated load becomes that of punching shear.If the material of the deck slab has the same stress-strain characteristics in both tension and compression, the slab will not crack and, as shown in Fig. 4.9 (b), will not develop the net compressive force and hence the arching action.In the punching shear type of failure, a frustum separates from the rest of the slab, as shown in schematically in Fig. 4.10. It is noted that in most failure tests, the diameter of the lower end of the frustrum extends to the vicinity of the girders.From analytical and confirmatory laboratory studies, it was established that the most significant factor influencing the failure load of a concrete deck slab is the confinement of the panel under consideration. It was concluded that this confinement is provided by the expanse of the slab beyond the loaded area; its degree was founddifficult to assess analytically. A restraint factor, η, was used as an empirical measure of the confinement; its value is equal to zero for the case of no confinement and 1.0 for full confinement.The effect of various parameters on the failure load can be seen in Table 4.1, which lists the theoretical failure loads for various cases. It can be seen that an increase of the restraint factor from 0.0 to 0.5 results in a very large increase in the failure load. The table also emphasizes the fact that neglect of the restraint factor causes a gross underestimation of the failure load.It was concluded that design for flexure leads to the inclusion of large amounts of unnecessary steel reinforcement in the deck slabs, and that even the minimum amount of steel required for crack control against volumetric changes in concrete is adequate to sustain modern-day, and even future, highway vehicles of North America.It was recommended that for new construction, the reinforcement in a deck slab should be in two layers, with each layer consisting of an orthogonal mesh having the same area of reinforcement in each direction. The area of steel reinforcement in each direction of a mesh was suggested to be 0.2% of the effective area of cross-section of the slab. This empirical method of design was recommended for deck slabs with certain constraints.4.3.2 Pulsating Load Tests on Scale ModelsTo study the fatigue strength of deck slabs with reduced reinforcement, five small scale models with different reinforcement ratios in different panels were tested at the Queen's University at Kingston. Details of this study are reported by Batchelor et al. (1978).Experimental investigation confirmed that for loads normally encountered in North America deck slabs with both conventional and recommended reducedreinforcement have large reserve strengths against failure by fatigue. It was confirmed that the reinforcement in the deck slab should be as noted in sub-section 4.3.1. It is recalled that the 0.2% reinforcement requires that the deck slab must have a minimum restraint factor of 0.5.The work of Okada, et al. (1978) also deals with fatigue tests on full scale models of deck slabs and segments of severely cracked slab removed from eight to ten year old bridges. The application of these test results to deck slabs of actual bridges is open to question because test specimens were removed from the original structures in such a way that they did not retain the confinement necessary for the development of the arching action.4.3.3 Field TestingAlong with the studies described in the preceding sub-section, a program of field testing of the deck slabs of in-service bridges was undertaken by the Structures Research Office of the MTO. The testing consisted of subjecting deck slabs to single concentrated loads, simulating wheel loads, and monitoring the load-deflection characteristics of the slab. The testing is reported by Csagoly et al. (1978) and details of the testing equipment are given by Bakht and Csagoly (1979).Values of the restraint factor, η, were back-calculated from measured deflections.A summary of test results, given in Table 4.2, shows that the average value of η in composite bridges is greater than 0.75, while that for non-composite bridges is 0.42. It was concluded that for new construction, the restraint factor, η, can be assumed to have a minimum value of 0.5.Bakht (1981) reports that after the first application of a test load of high magnitude on deck slabs of existing bridges, a small residual deflection was observed in most cases. Subsequent applications of the same load did not result in further residual deflections. It is postulated that the residual deflections are caused by cracking of the concrete which, as discussed earlier, accompanies the development of the internal arching action. The residual deflections after the first cycle of loading suggest that either the slab was never subjected to loads high enough to cause cracking, or the cracks have 'healed' with time.第二部分汉语翻译4.2.2 在冲切剪应力下的实效模型我们已经知道在桥面板内部拱形系统的形成中,不仅纵向而且横向也被完全约束限制是完全必要的。

本科毕业论文外文参考文献译文及原文学院经济与贸易学院专业经济学(贸易方向)年级班别2007级 1 班学号3207004154学生姓名欧阳倩指导教师童雪晖2010 年 6 月 3 日目录1 外文文献译文(一)中国银行业的改革和盈利能力(第1、2、4部分) (1)2 外文文献原文(一)CHINA’S BANKING REFORM AND PROFITABILITY(Part 1、2、4) (9)1概述世界银行(1997年)曾声称,中国的金融业是其经济的软肋。

当一国的经济增长的可持续性岌岌可危的时候,金融业的改革一直被认为是提高资金使用效率和消费型经济增长重新走向平衡的必要(Lardy,1998年,Prasad,2007年)。

事实上,不久前,中国的国有银行被视为“技术上破产”,它们的生存需要依靠充裕的国家流动资金。

但是,在银行改革开展以来,最近,强劲的盈利能力已恢复到国有商业银行的水平。

但自从中国的国有银行在不久之前已经走上了改革的道路,它可能过早宣布银行业的改革尚未取得完全的胜利。

此外,其坚实的财务表现虽然强劲,但不可持续增长。

随着经济增长在2008年全球经济衰退得带动下已经开始软化,银行预计将在一个比以前更加困难的经济形势下探索。

本文的目的不是要评价银行业改革对银行业绩的影响,这在一个完整的信贷周期后更好解决。

相反,我们的目标是通过审查改革的进展和银行改革战略,并分析其近期改革后的强劲的财务表现,但是这不能完全从迄今所进行的改革努力分离。

本文有三个部分。

在第二节中,我们回顾了中国的大型国有银行改革的战略,以及其执行情况,这是中国银行业改革的主要目标。

第三节中分析了2007年的财务表现集中在那些在市场上拥有浮动股份的四大国有商业银行:中国工商银行(工商银行),中国建设银行(建行),对中国银行(中银)和交通银行(交通银行)。

引人注目的是中国农业银行,它仍然处于重组上市过程中得适当时候的后期。

第四节总结一个对银行绩效评估。

Single-chip1.The definition of a single-chipSingle-chip is an integrated on a single chip a complete computer system .Even though most of his features in a small chip,but it has a need to complete the majority of computer components:CPU,memory,internal and external bus system,most will have the Core.At the same time,such as integrated communication interfaces,timers,real-time clock and other peripheral equipment.And now the most powerful single-chip microcomputer system can even voice ,image,networking,input and output complex system integration on a single chip.Also known as single-chip MCU(Microcontroller),because it was first used in the field of industrial control.Only by the single-chip CPU chip developed from the dedicated processor. The design concept is the first by a large numberof peripherals and CPU in a single chip,the computer system so that smaller,more easily integrated into the complex and demanding on the volume control devices.INTEL the Z80 is one of the first design in accordance with the idea of the processor,From then on,the MCU and the development of a dedicated processor parted ways.Early single-chip 8-bit or all the four.One of the most successful is INTELs 8031,because the performance of a simple and reliable access to a lot of good praise.Since then in 8031to develop a single-chip microcomputer system MCS51 series.based on single-chip microcomputer system of the system is still widely used until now.As the field of industrial control requirements increase in the beginning of a 16-bit single-chip,but not ideal because the price has not been very widely used.After the90s with the big consumer electronics product development,single-chip technology is a huge improvement.INTEL i960 series with subsequent ARM in particular ,a broad range of application,quickly replaced by 32-bit single-chip 16-bit single-chip performance has been the rapid increase in processing power compared to the 80s to raise a few hundred times.At present,the high-end 32-bit single-chip frequency over 300MHz,the performance of the mid-90s close on the heels of a special processor,while the ordinary price of the model dropped to one U.S dollars,the most high-end models,only 10 U.S dollars.Contemporary single-chip microcomputer system is no longer only the bare-metal environment in the development and use of a large number of dedicated embedded operating system is widely used in the full range of single-chip microcomputer.In PDAs and cellphones as the coreprocessing of high-end single-chip or even a dedicated direct access to Windows and Linux operating systems.More than a dedicated single-chip processor suitable for embedded systems,so it was up to the application.In fact the number of single-chip is the worlds largest computer.Modern human life used in almost every piece of electronic and mechanical products will have a single-chip integration.Phone,telephone,calculator,home applicances,electronic toys,handheld computers and computer accessories such as a mouse in the Department are equipped with 1-2 single chip.And personal computers also have a large number of single-chip microcomputer in the workplace.Vehicles equipped with more than 40 Department of the general single-chip ,complex industrial control systems and even single-chip may have hundreds of work at the same time!SCM is not only far exceeds the number of PC and other integrated computing,even more than the number of human beings.2.single-chip introducedSingle-chip,also known as single-chip microcontroller,it is not the completion of a logic function of the chip,but a computer system integrated into a chip.Speaking in general terms: a single chip has become a computer .Its small size,light weight,cheap,for the learning,application and development of facilities provided .At the same time,learning to use the principle of single-chip computer to understand and structure the best choice.Single-chip and computer use is also similar to the module,such as CPU,memory,parallel bus, as well as the role and the same hard memory,is it different from the performance of these components are relatively weak in our home computer a lot,but the price is low ,there is generally no more than 10yuan,,can use it to make some control for a class of electrical work is not very complex is sufficient.We are using automatic drum washing machines, smoke hood,VCD and so on inside the home appliances can see its shadow! It is mainly as part of the core components of the control.It is an online real-time control computer,control-line is at the scene,we need to have a stronger anti-interference ability,low cost,and this is off-line computer(such as home PC)The main difference.By single-chip process,and can be amended.Through different procedures to achieve different functions,in particular the special unique features,this is the need to charge other devices can do a great effort,some of it is also difficult to make great efforts to do so .A function is not very complicated fi the United States the development of the 50s series of 74 or 60 during the CD4000series to get these pure hardware,the circuit must be a big PCB board !However,if the United States if the successful 70s seriesof single-chip market ,the result will be different!Simply because the adoption of single-chip preparation process you can achieve high intelligence,high efficiency and high reliability!Because of cost of single-chip is sensitive,so the dominant software or the lowest level assembly language,which is in addition to the lowest level for more than binary machine code of the language ,since such a low-level so why should we use ?Many of the seniors language has reached a level of visual programming why is it not in use ?The reason is simple ,that is,single-chip computer as there is no home of CPU,also not as hard as the mass storage device.A visualization of small high-level language program,even if there is only one button which will reach the size of dozens of K! For the home PCs hard drive is nothing,but in terms of the single-chip microcomputer is unacceptable.Single-chip in the utilization of hardware resources have to do very high ,so the compilation of the original while still in heavy use .The same token ,if the computer giants operating system and appplications run up to get the home PC,homePCcan not afford to sustain the same.It can be said that the twentieth century across the three “power”of the times,that is ,the electrical era,the electronic age and has now entered the computer age. However ,such a computer,usually refers to a personal computer,or PC.It consisits of the host ,keyboards,displays .And other components.There is also a type of computer,not how most people are familiar with . This computer is smart to give a variety of mechanical single-chip(also known as micro-controller).As the name suggests,these computer systems use only the minimum of an integrated circuit to make a simple calculation and control. Because of its small size,are usually charged with possession of machine in the “belly”in. It in the device,like the human mind plays a role, it is wrong,the entire device was paralyzed .Now,this single chip has a very wide field of use,such as smart meters,real-time industrial control,communications equipment,navigation systems,and household appliances. Once a variety of products with the use of the single-chip ,will be able to play so that the effectiveness of product upgrading,product names often adjective before the word “intelligent”,such as was hing machines and so intelligent.At present,some technical personnel of factories or other amateur electrtonics developers from engaging in certain products ,not the circuit is too complex ,that is functional and easy to be too simple imitation.The reason may be the product not on the cards or the use of single-chip programmable logic device on the other.3.single-chip historysingle-chip 70 was born in the late 20th century,experienced a SCM,MCU,SOC three stages.Single-chip micro-computer 1.SCM that(Single Chip Microcomputer)stage,is mainly a single from to find the best of the best embedded systems architecture.”Innovation model”to be successful,lay the SCM with the general-purpose computers,a completely different path of development . In embedded systems to create an independent development path,Intel Corporation credit.That is 2.MCU microcontroller(Micro Controller Unit)stage,the main direction of technology development: expanding to meet the embedded applications,the target system requirements for the various peripheral circuits and interface circuits,to highlingt the target of intelligent control.It covers all areas related with the objectSystem,therefore,the development of MCU inevitably fall on the heavy electrical,electronics manufacturers. From this point of view ,Intels development gradually MCU has its objective factors.MCU in the development ,the most famous manufacturers when the number of Philips Corporation.Philips in embedded applications for its enormous advantages,the MCS-51 from the rapid deveploment of single-chip micro-computer to the microcontroller.Therefore,when we look back at the path of development of embedded systems,Intel and Philips do not forget the historical merits.3.Single-chip is an independent embedded systems development,to the MCU an important factor in the development stage,is seeking applications to maximize the natural trend .With the mico-electronics technology,IC design,EDA tools development,based on the single-chip SOC design application systems will have greater development. Therefore,the understanding of single-chip micro-computer from a single ,monolithic single-chip microcontroller extends to applications.4.Single-chip applicationsAt present,single-chip microcomputer to infiltrate all areas of our lives,which is very difficult to find the area of almost no traces of single-chip microcomputer.Missile navigation equipment,aircraft control on a variety of instruments,compuer network communications and data transmission,industrial automation,real-time process control and data processing ,are widely used in a variety of smart IC card,limousine civilian security systems,video recorders,cameras,the control of automatic washing machines,as well as program-controllde toys,electronic pet,etc,which are inseparable from the single-chip microcomputer.Not to mention the field of robot automation ,intelligent instrumentation,medical equipment has been. Therefore,the single- chip learning ,development and application to a large number of computer applications and intelligent control of scientists,engineers.Single-chip widely used in instruments and meters,household appliances,medical equipment ,acrospace,specialized equipment and the intellingent management in areas such as process control,generally can be divided into the following areas:1.In the smart application of instrumentationSingle-chip with small size,low power consumption,control,and expansion flexibility , miniaturization and ease of sensors,can be realized,suchvoltage,power,frequency,humidity,temperature,flow,speed,thickness,angle,length,hardness,elemen t,measurement of physical pressure. SCM makes use of digital instrumentation,intelligence,miniaturization and functional than the use of electronic or digital circuitry even stronger.For example,precision measurement equipment(power meter,oscilloscope,and analyzer).2.In the industrial controlMCU can constitute a variety of control systems,data acquisition system.Such as factory assembly line of intelligent management ,intelligent control of the lift ,all kinds of alarm systems ,and computer networks constitute a secondary control system.3.In the applicationof household appliancesIt can be said that almost all home appliances are using the single-chip control,electric rice from favorable,washing machines,refrigerators,air conditioners,color TV and other audio video equipment,and then to the electronic weighing equipment,all kinds ,everywhere.4.On computer networks and communication applications in the field ofGenerally with the modern single-chip communication interface,can be easily carried out with computer carried out with computer data communications,computer networks and in inter-application communications equipment to provide an excellent material conditions,the communications equipment to provide an excellent material condition,from the mobile phone ,telephone , mini-program-controlled switchboards,buiding automated communications system call,the train wireless communications,and then you can see day-to-day work of mobile phones,Mobile communications,such as radios.5.Single-chip in the field of medical equipment applicationsSingle-chip microcomputer in medical devices have a wide range of purpose,such as medical ventilator,various analyzers,monitors,ultrasonic diagnostic equipment and hospital call systems.6.In a variety of large-scale electrical applications of modularSome special single-chip design to achieve a specific function to carry out a variety of modular circuitapplications,without requiring users to understand its internal structure.Integrated single-chip microcomputer such as music ,which seems to be simpleFunctions,a miniature electronic chip in a pure(as distinct from the principle of tape machine),would require a complex similar to the principle of the computer.

聚亚烷基二醇的化学结构和它们在含水环境中的好氧生物降解性之间的关系简要:使用一组聚合流体,其中包括聚乙二醇、聚丙二烯(PPG)、不同EO/PO 比率的环氧乙烷(EO)的无规共聚物和环氧丙烷(PO),对聚亚烷基醇(PAG)的化学结构和它们的生物降解性之间的关系进行研究以及用PAG的醚和酰基部分封端。

被测试的PAG中有一个均分子量范围在350-3600Da,它们的差异是由其聚合物主链的直链(二醇型)或支链(三元醇型)分子。

PAG的最终生物降解能力是根据ISO14593(CO2顶空试验)用非预曝光(如在OECD310试验)和预曝光(改编)接种物来确定。

带有PPG结构和二元醇或三元醇的EO/PO共聚物,均分子量不超过1000沓的PAG,被认为是易于生物降解的。

他们的最终生物降解可超过60%的限制(根据OECD310测试标准)。

具有共聚结构并且MW值在1000-3600之间的PAG不易生物降解,但它们可以被看做是那些固有的最终降解物。

在PAG结构中EO含量的增长和末端羟基的酰化与羧酸基团有利地影响了他们的生物降解性。

含末端醚基团封端的PAG似乎是耐生物降解的。

关键词生物降解、聚亚烷基二醇、PAG、PPG、封顶PAG、ISO14593。

引言:术语中的聚亚烷基二醇-PAG,以及在相关文献中的PAG,例如,聚乙二醇,聚醚和聚(烯化氧)中使用的PAG术语都是带有环氧化物结构烯化氧聚合得到的化合物。

PAG主要是通过使用乙烯和丙烯的氧化物合成的,不常使用丁二醇和更高的烯烃氧化物。

PAG类化合物(不同的分子量,性能和应用)最常用的包括氧化乙烯或丙烯均聚物氧化物以及乙烯和丙烯氧化物的无规或嵌段共聚物。

PAG的分子结构不仅取决于种类和亚烷基氧化物的比例,而且还取决于用于聚合反应的引发剂分子的类型(单-,二-或多官能分子具有2个以上活泼氢原子)。

引发剂影响PAG分子的末端羟基基团和聚合物链的类型,其可以是线性的(单醇及二醇型)或支链的(多元醇的数类型)。

外文文献翻译(含:英文原文及中文译文)文献出处:Y Miyazaki. A Brief Description of Interior Decoration [J]. Building & Environment, 2005, 40(10):41-45.英文原文A Brief Description of Interior DecorationY Miyazaki一、An interior design element1 Spatial elementsThe rationalization of space and giving people a sense of beauty is the basic task of design. We must dare to explore the new image of the times and technologies that are endowed with space. We should not stick to the spatial image formed in the past.2 color requirementsIn addition to affecting the visual environment, indoor colors also directly affect people's emotions and psychology. Scientific use of color is good for work and helps health. The proper color processing can meet the functional requirements and achieve the beauty effect. In addition to observing the general laws of color, interior colors also vary with the aesthetics of the times.3 light requirementsHumans love the beauty of nature and often direct sunlight into theinterior to eliminate the sense of darkness and closure in the interior, especially the top light and the soft diffuse light, making the interior space more intimate and natural. The transformation of light and shadow makes the interior richer and more colorful, giving people a variety of feelings.4 decorative elementsThe indispensable building components such as columns, walls, and the like in the entire indoor space are combined with the function and need to be decorated to jointly create a perfect indoor environment. By making full use of the texture characteristics of different decorative materials, you can achieve a variety of interior art effects with different styles, while also reflecting the historical and cultural characteristics of the region.5 furnishingsIndoor furniture, carpets, curtains, etc., are all necessities of life. Their shapes are often furnished and most of them play a decorative role. Practicality and decoration should be coordinated with each other, and the functions and forms of seeking are unified and changed so that the interior space is comfortable and full of personality.6 green elementsGreening in interior design is an important means to improve the indoor environment. Indoor flowering trees are planted, and the use ofgreenery and small items to play a role in diffusing indoor and outdoor environments, expanding the sense of interior space, and beautifying spaces all play an active role.二、The basic principles of interior design1 interior decoration design to meet the functional requirementsThe interior design is based on the purpose of creating a good indoor space environment, so as to rationalize, comfort, and scientize the indoor environment. It is necessary to take into account the laws of people's activities to handle spatial relationships, spatial dimensions, and spatial proportions; to rationally configure furnishings and furniture, and to properly resolve indoor environments. V entilation, lighting and lighting, pay attention to the overall effect of indoor tone.2 interior design to meet the spiritual requirementsThe spirit of interior design is to influence people's emotions and even influence people's will and actions. Therefore, we must study the characteristics and laws of people's understanding; study the emotions and will of people; and study the interaction between people and the environment. Designers must use various theories and methods to impact people's emotions and sublimate them to achieve the desired design effect. If the indoor environment can highlight a certain concept and artistic conception, then it will have a strong artistic appeal and better play its role in spiritual function.3 Interior design to meet modern technical requirementsThe innovation of architectural space is closely related to the innovation of structural modeling. The two should be harmonized and unified, fully considering the image of the structural Sino-U.S. and integrating art and technology. This requires that interior designers must possess the necessary knowledge of the type of structure and be familiar with and master the performance and characteristics of the structural system. Modern interior design is in the category of modern science and technology. To make interior design better meet the requirements of spiritual function, we must maximize the use of the latest achievements in modern science and technology.4 Interior design must meet the regional characteristics and national style requirementsDue to differences in the regions where people live, geographical and climatic conditions, the living habits of different ethnic groups are not the same as cultural traditions, and there are indeed great differences in architectural styles. China is a multi-ethnic country. The differences in the regional characteristics, national character, customs, and cultural literacy of various ethnic groups make indoor decoration design different. Different styles and features are required in the design. We must embody national and regional characteristics to evoke people’s national self-respect and self-confidence.三、Points of interior designThe interior space is defined by the enclosure of the floor, wall, and top surface, thus determining the size and shape of the interior space. The purpose of interior decoration is to create a suitable and beautiful indoor environment. The floor and walls of the interior space are the backdrop for people and furnishings and furnishings, while the differences on the top surface make the interior space more varied.1 Base decoration ----- Floor decorationThe basic surface ----- is very important in people's sights. The ground floor is in contact with people, and the line of sight is near, and it is in a dynamic change. It is one of the important factors of interior decoration. Meet the following principles:2 The base should be coordinated with the overall environment to complement each other and set off the atmosphereFrom the point of view of the overall environmental effect of space, the base should be coordinated with the ceiling and wall decoration. At the same time, it should play a role in setting off the interior furniture and furnishings.3 Pay attention to the division, color and texture of the ground patternGround pattern design can be roughly divided into three situations: The first is to emphasize the independent integrity of the pattern itself,such as meeting rooms, using cohesive patterns to show the importance of the meeting. The color should be coordinated with the meeting space to achieve a quiet, focused effect; the second is to emphasize the pattern of continuity and rhythm, with a certain degree of guidance and regularity, and more for the hall, aisle and common space; third It emphasizes the abstractness of the pattern, freedom, and freedom, and is often used in irregular or layout-free spaces.4 Meeting the needs of the ground structure, construction and physical properties of the buildingWhen decorating the base, attention should be paid to the structure of the ground floor. In the premise of ensuring safety, it is convenient for construction and construction. It cannot be a one-sided pursuit of pattern effects, and physical properties such as moisture-proof, waterproof, thermal insulation, and thermal insulation should be considered. need. The bases are available in a wide variety of types, such as: wooden floors, block floors, terrazzo floors, plastic floors, concrete floors, etc., with a wide variety of patterns and rich colors. The design must be consistent with the entire space environment. Complementary to achieve good results.四、wall decorationIn the scope of indoor vision, the vertical line of sight between the wall and the person is in the most obvious position. At the same time, thewall is the part that people often contact. Therefore, the decoration of the wall is very important for the interior design. The following design principles must be met: 1 IntegrityWhen decorating a wall, it is necessary to fully consider the unity with other parts of the room, and to make the wall and the entire space a unified whole.2 PhysicalThe wall surface has a larger area in the interior space, and the status is more important and the requirements are higher. The requirements for sound insulation, warmth protection, fire prevention, etc. in the interior space vary depending on the nature of the space used, such as the guest room, high requirements. Some, while the average unit canteen, requiresa lower number.3 ArtistryIn the interior space, the decorative effect of the wall plays an important role in rendering and beautifying the indoor environment. The shape of the wall, the partition pattern, the texture and the interior atmosphere are closely related to each other. In order to create the artistic effect of the interior space, the wall The artistry of the surface itself cannot be ignored.The selection of wall decoration styles is determined according to the above principles. The forms are roughly the following: plasteringdecoration, veneering decoration, brushing decoration, coil decoration. Focusing on the coil decoration here, with the development of industry, there are more and more coils that can be used to decorate walls, such as: plastic wallpaper, wall cloth, fiberglass cloth, artificial leather, and leather. These materials are characterized by the use of It is widely used, flexible and free, with a wide variety of colors, good texture, convenient construction, moderate prices, and rich decorative effects. It is a material that is widely used in interior design.五、Ceiling decorationThe ceiling is an important part of the interior decoration, and it is also the most varied and attractive interface in the interior space decoration. It has a strong sense of perspective. Through different treatments, the styling of lamps and lanterns can enhance the space appeal and make the top surface rich in shape. Colorful, novel and beautiful.1 Design principlesPay attention to the overall environmental effects.The ceiling, wall surface and base surface together make up the interior space and jointly create the effects of the indoor environment. The design should pay attention to the harmonization of the three, and each has its own characteristics on a unified basis.The top decoration should meet the applicable aesthetic requirements.In general, the effect of indoor space should be lighter and lighter. Therefore, it is important to pay attention to the simple decoration of the top decoration, highlight the key points, and at the same time, have a sense of lightness and art.The top decoration should ensure the rationality and safety of the top structure. Cannot simply pursue styling and ignore safety2 top design(1) Flat roofThe roof is simple in construction, simple in appearance, and convenient in decoration. It is suitable for classrooms, offices, exhibition halls, etc. Its artistic appeal comes from the top shape, texture, patterns, and the organic configuration of the lamps.(2) Convex ceilingThis kind of roof is beautiful and colorful, with a strong sense of three-dimensionality. It is suitable for ballrooms, restaurants, foyers, etc. It is necessary to pay attention to the relationship between the primary and secondary relationships and the height difference of various concavo-convex layers. It is not appropriate to change too much and emphasize the rhythm of rhythm and the artistry of the overall space. .(3) Suspended ceilingV arious flaps, flat plates or other types of ceilings are hung under the roof load-bearing structures. These ceilings are often used to meetacoustic or lighting requirements or to pursue certain decorative effects. They are often used in stadiums, cinemas, and so on. In recent years, this type of roof has also been commonly used in restaurants, cafes, shops, and other buildings to create special aesthetics and interests.(4) Well format ceilingIt is in the form of a combined structural beam, in which the main and secondary beams are staggered and the relationship between the wells and beams, together with a ceiling of lamps and gypsum floral designs, is simple and generous, with a strong sense of rhythm.(5) Glass ceilingThe halls and middle halls of modern large-scale public buildings are commonly used in this form, mainly addressing the needs of large-scale lighting and indoor greening, making the indoor environment richer in natural appeal, and adding vitality to large spaces. It is generally in the form of a dome, a cone, and a zigzag. In short, interior decoration design is a comprehensive discipline, involving many disciplines such as sociology, psychology, and environmental science, and there are many things that we need to explore and study. This article mainly elaborated the basic principles and design methods of interior decoration design. No matter what style belongs to the interior design door, this article gives everyone a more in-depth understanding and comprehension of interior design.

采用新技术以增强集装箱运输的安全性
摘要:通过技术加强集装箱运输安全性在一个运输链中已成为一种必要,在集装箱运输链(包括托运人,收货人,货运代理,运输经营人,海上运输,货柜码头经营者,海关当局和政府机构)中采用的一些先进的技术有:无线电频率识别(RFID )技术,智能框倡议和集装箱非侵入性检查(设施)技术等。

文章探讨了不同类型体制的影响,如制度,规范和标准。

从港口的一方已采取主动行动,通过技术运用集装箱运输安全有了进一步加强。

那些遵循其他组织制定的标准,通过标准产生的影响可以帮助港口管理者更好地处理集装箱运输中安全的压力,从而使他们能够适应其集装箱运输链合作伙伴对集装箱运输安全的要求。

在他们面临集装箱运输链合作伙伴对集装箱运输安全的要求,通过运用新技术以提高集装箱运输的安全性是最为重要的一点。

一、新技术运用于集装箱运输
自从911事件以来,国际社会已逐步增强对恐怖主义潜在威胁的防范,以国际贸易和运输系统,最为敏锐警觉,改进集装箱运输结果在加强集装箱转运港口安全性,特别是强调保护脆弱的集装箱海运贸易,加强海上运输的保护,防止威胁和危害,美国国土安全部在2004年制定了一些战略计划:
1.意识:在集装箱运输中加强安全重要性的认识。

2.预防:在国内和国际上建立和完善一个有效的集装箱运输的安全制度来检测和减轻威胁。

3.保护:增加军事和民事保护存在有可能威胁的港口,以保障集装箱运输的发展。

4.反应:改善响应事件有关的安全防卫措施。

5. 复原:在自然灾害、恐怖主义行为或其他紧急情况之后,如何尽快恢复服务。

通过采取分层的方式处理运输安全,美国国土安全部提出了系统的保安措施,确保防护到位其他集装箱运输链中的合作者(美国国土安全部,2004年)。

具体来说,分层次的安全的措施旨在保护三个阶段的旅程,即在海外,在过境和海岸,而每一个阶段,包括了一系列的安全规划,除了这些层次的保障措施,技术发挥了重要作用。

技术不但提高了集装箱货物运输效率,还增强了集装箱货物运输的安全性。

在2005年在集装箱运输中技术采用比较重要的三个技术,即射频识别(RFID )技术,智能框倡议和非侵入性检查(设施),它可以部署支持集装箱运输链,以改善集装箱运输的安全。

(一)RFID技术
虽然美国海关最近暗示,美国的政府不可能对集装箱运输行业采取主动行动,但是有关部门仍在发展有关的技术,如电变速器集装箱密封(电子印章)的集装箱安全(Edmonson ,2006),并作出相当大的努力取得了在集装箱运输行业内制定标准的RFID (Koch,2005)。

集装箱的RFID标签可以充当许可证,包括有关货柜信息,使托运人嵌入运输货物的相关数据,RFID标签也可作为一个电子印章,提供一个自动化的,有效的途径和有效的手段,以监测的完整的集装箱,提醒官员集装箱的相关信息是否被篡改。

通过集装箱运输行业技术创新,以提高集装箱运输的安全,在使用RFID技术时,只有足够的装备管理和供应链协作,才可以在集装箱运输链中获取利益。

的确,这是这种技术的运用面临的主要挑战之一,是通过RFID技术在集装箱运输链是需要制定一个商定的标准,以便有效地执行。

不过,类似的其他类型的信息技术,广泛采用RFID技术的使用者之间(出口商,进口商,运输,货柜码头经营者等),在他们之中可以创建集装箱运输链的网络。

这个方法不仅将缩短投资回报的技术投资,而且还改善集装箱运输的效率。

(二)非侵入性检查
另外一个关键的安全问题是可能使用的集装箱运输中存在核与放射性的物质和设备。

因此,海关和边境保护局(CBP )使用大型X射线和伽玛射线非侵入性的集装箱检查(设施)和放射性传感器系统的屏幕上安全和有效地运送违禁品,如大规模杀伤性武器和放射性物质(美国国土安全部,2004年)。

国家信息基础设施的技术已经部署在一些港口,用以便利地检查集装箱。

利用国家信息基础设施技术让港口运营商对较大部分集装箱到达其港口在更短的时间内进行必要的检测。

集装箱检测技术已经证明了其价值,集装箱的安全是非常重要的,因为这种技术使国家信息基础设施进入港口的安全检测。

(Rodriguez-Alvarez et al.,2007) 。

(三)传播技术
集装箱运输的安全威胁带来的不确定性对跨国企业和世界经济有着重大的影响(Barnes and Oloruntoba,2005) 。

政府的奖励或惩罚,引导着港口以及企业如何管理自己的集装箱运输安全(Spich and Grosse,2005) 。

例如,一个企业如果不能管理其集装箱运输的安全,部署适当的技术来跟踪和追踪的地位,贸易项目就有可能因为盗窃,损坏等一些意外而遭受到经济损失。

因此,至关重要的是企业组织在集装箱运输链中保证和保护他们的集装箱安全不受意外打击,通过适当的传播技术可以实现。

通过技术加强安全的集装箱运输的概念与创新扩散密切相关,其中提到集装箱运输,其中一个创新是通过一定的渠道传达随着时间的推移成员的社会制度(Rogers,1995)。

许多事先研究这技术(e.g.Loh and Venkatraman,1992;Hu et al.,1997),这个角度来看,假定合理采用作出决定和选择的基础上的信息,收到了通过沟通和网络(Rogers,1995) 。

然而,一个关键的假设的概念合并是自由和独立的选择还是通过(或不通过)创新(March,1978)。

政府不承认体制同构过程,这可能会影响政府的决定,它通过创新(DiMaggio and Powell,1983;Abrahamson,1991) ,扩散的概念来解释技术集装箱运输安全,坚实的基础理论来解释通过技术组织集装箱运输链,从而提高集装箱运输的安全性。

(四)模仿
另一种类型体制同构力量的不确定性是鼓励模仿集装箱运输链管理的做法。

当一个组织已模糊不清的目标和工作在不稳定的环境精神的无处不在,持续的,和不可预知的安全威胁(Spich andGrosse,2005) ,它的模式本身对其他组织,特
别是在组织筹措密切与此相关的,以应对不确定的运输安全。

追随者可能不知道他们的模仿行为该组织正在模仿可能仅仅充当一个方便的来源。

模仿集装箱运输链管理做法(DiMaggio andPowell,1983)。

发现和学习的一种技术,集装箱运输的安全发生在间接通过行业协会,雇员转让和信息互换时组织面临着一个不确定的环境中,他们尝试超越其竞争对手,通过低成本或分化(Porter,1996) 。

例如,新的技术解决方案的集装箱运输的安全,如采用RFID技术的智能集装箱,可以提高集装箱安全,以及提高集装箱港口的知名度,在整个集装箱运输链中能够及时追查集装箱的潜力业务和安全的优势并得到更准确和及时的数据可提供的智能集装箱内有RFID设备的信息网络。

通过有效地沿着集装箱运输链,采用RFID 智能盒可能是一个工具,以超越竞争对手。

在集装箱运输安全,在寻求战略工具和超越竞争对手的做法,一些组织自觉或不自觉地模仿的做法,其合作伙伴在其集装箱运输链,因为如下:1组织很容易获得的集装箱运输链管理做法及其合作伙伴通过实施集装箱安全措施。

2. 属性似乎帐户成功集装箱运输链管理做法的合作伙伴很容易观察到的模仿组织集装箱运输链。

3.组织往往愿意分享他们的经验和专门知识如何在加强集装箱运输安全的相互合作,为分享信息和知识的好处,而他们以及他们服务于同一集装箱运输链。

方便了解合作伙伴集装箱运输链管理实践,认识到成功的关键因素,以及传播集装箱运输管理知识将导致有意或模仿的做法采用的技术,以提高集装箱运输安全性。

通过将开始从传播集装箱安全技术学的管理技术。

往往自己的模式类似的组织在自己的领域,他们认为是合法的和成功的(Kraatz and Zajac,1996),通过模仿和获取集装箱运输的安全性,创新和做法,被证明是由于成功用集装箱运输的安全措施。
