毕业论文-外文资料翻译[管理资料]
附件1:外文资料翻译译文数据库简介1.数据库管理系统(DBMS)。
众所周知,数据库是逻辑上相关的数据元的集合。
这些数据元可以按不同的结构组织起来,以满足单位和个人的多种处理和检索的需要。
数据库本身不是什么新鲜事——早期的数据库记录在石头上或写在名册上,以及写入索引卡中。
而现在,数据库普遍记录再可磁化的介质上,并且需要用计算机程序来执行必需的存储和检索操作。
在后文中你将看到除了简单的以外,所有数据库中都有复杂的数据关系及其连接。
处理与创建、访问以及维护数据库记录有关的复杂任务的系统软件包叫做数据库管理系统(DBMS)。
DBMS软件包中的程序在数据库极其用户间建立了接口(这些用户可以是应用程序员、管理员以及其他需要信息和各种操作系统的人员)。
DBMS可组织、处理和显示从数据库中选择的数据元。
该功能使决策者可以搜索、试探和查询数据库的内容,从而对在正式报告中没有的、不再出现的且无计划的问题作出回答。
这些问题最初可能是模糊的并且是定义不清的,但是人们可以浏览数据库直到获得问题的答案。
也就是说DBMS将“管理”存储的数据项,并从公共数据库中汇集所需的数据项以回答那些非程序员的询问。
在面向文件的系统中,需要特定信息的用户可以将他们的要求传送给程序员。
该程序员在时间允许时,将编写一个或多个程序以提取数据和准备信息。
但是,使用DBMS可为用户提供一种更快的、用户可以选择的通信方式。
顺序的、直接的以及其它的文件处理方式常用于单个文件中数据的组织和构造,而DBMS能够访问和检索非关键记录字段的数据,即DBMS能够将几个大文件中逻辑相关的数据组织并连接在一起。
逻辑结构。
确定这些逻辑关系是数据管理者的任务,由数据定义语言完成。
DBMS 在存储、访问和检索操作过程中可选用以下逻辑结构技术:(1)表结构。
在该逻辑方式中,记录通过指针链接在一起。
指针是记录中的一个数据项,它指出另一个逻辑相关的记录的存储位置,例如,顾客主文件的记录将包含每个顾客的姓名和地址,而且该文件中的每个记录都由一个帐号标识。

外文翻译ANALYSIS OF HVAC SYSTEM ENERGYCONSERVATIONIN BUILDINGSABSTRACTE conomic development and people's increasing demand for energy, but the nature of the energy is not inexhaustible. Environment and energy issues become increasingly acute, if no measures are taken, then the energy will limit the rapid economic development of the question.With the improvement of living standard, building energy consumption in the proportion of total energy consumption is increasing. In developed countries, building energy consumption accounts for 40% of total energy consumption of the community, while the country despite the low level of socio-economic development, but the building energy consumption has nearly 30% of total energy consumption, and still rising. Therefore, in western countries or in China, building energy consumption is affecting the socio-economic status of the overall development of the question. In building energy consumption, the energy consumption for HVAC systems has accounted for 30% of building energy consumption -50%, with the extensive application of HVAC, energy consumption for HVAC systems will further increase Great. HVAC systems are often coupled with high-quality electric energy, and our power and relatively tight in some areas, lack of energy supply and demand which is bound to lead to further intensification of contradictions. Therefore, energy-saving heating, higher professional requirements is inevitable across the board.KEYWORDS:energy-saving,HVAC1. Energy saving design measures should be takenRapid changes in science and technology today, area HVAC new technologiesemerge, we can achieve a variety of ways of energy saving HVAC systems.1.1 Starting from the design, selecting, designing HVAC systems, so that the efficient state of the economy running.Design is a leading engineering, system design will directly affect its performance. The building load calculation is an important part of the design, a common problem is that the current design of short duration, many designers to save time, wrong use of the design manual for the design or preliminary design estimates of cold, heat load with the unit construction area of cold, heat load index, direct construction design stage as hot and cold load to determine the basis, often making the total load is too large, resulting in heating equipment, air conditioning is too large, higher initial investment, operating costs, increased energy consumption.1.2 using the new energy-saving air-conditioning and heating comfort and healthy mannerAffect human thermal comfort environment of many parameters, different environmental parameters can get the same effect of thermal comfort, but for different heat and moisture parameters of the environment of its energy consumption air conditioning system is not the same.1.3 Actual situation of a reasonable choice of cold and heat sources, seek to achieve diversification of cold and heat sourceWith the extensive application of HVAC systems on non-renewable energy consumption also rose sharply, while the broken part of the ecological environment are becoming increasingly intensified. How to choose a reasonable heating sources, has caused widespread concern of all parties.1.4 to enhance the use of hot and cold recycling of the work, to achieve maximum energyHVAC systems to improve energy efficiency is one of the ways to achieve energy-saving air-conditioning. Heat recovery system installed mainly through energy recovery, with the air from wind energy to deal with new, fresh air can reduce the energy required for processing, reducing the load, to save energy. In the choice of heat recovery, the should be integrated with the local climate Tiao Jian, Jing Ji situation, Gong Cheng actual situation of harmful exhaust gases of the situation in avariety of factors Deng integrated to determine the Xuanyong suitable heat recovery, so as to achieve Hua Jiao Shao's investment, recovery of more heat (cold) the amount of purpose.1.5 focus on development of renewable energy, and actively promoting new energyAs the air-conditioning systems used in high-grade, non-renewable energy resources and environmental problems caused by the increasingly prominent, have to develop some reasonable and effective renewable energy to ease the current tensions. To heat (cold) and solar and other renewable resources used in air conditioning and refrigeration, has certain advantages, but also clean and pollution-free. Ground Source Heat Pump is a use of shallow and deep earth energy, including soil, groundwater, surface water, seawater, sewage, etc. as a cold source in winter and summer heat is not only heating but also a new central air-conditioning system cooling.2. Saving design problemsAchieve energy-saving HVAC systems, now has a lot of mature conditions, but in practical applications there are some problems:2.1 The issue of public awareness of energy conservationThe past is not enough public understanding of energy, and on the air conditioning is also very one-sided view. For a comfort of air conditioning system or heating system, should the human body has a very good comfort. But the prevailing view now is: the colder the better air-conditioning, heating the more heat the better. This is obviously we seek the comfort of air conditioning is contrary to the view. In fact, this not only greatly increase the energy consumption of air conditioning heating, indoor and outdoor temperature and because of the increase, but also to the human body's adaptability to different environmental decline, lowering the body immunity. Therefore, we need to improve advocacy efforts to change public to the traditional understanding of air conditioning and heating, vigorous publicity and promotion in accordance with building standards and the cold heat energy metering devices to collect tolls, raise public consciousness of energy.2.2 The design concept of the problemReasonable energy-saving design is a prerequisite. At present, some designers due to inadequate attention to design empirical value when applied blindly, resulting in the increase of the initial investment, energy consumption surprising, therefore recommended that the government functions and the energy-saving review body, to increase the monitoring of the HVAC air-conditioning energy saving efforts enhance staff awareness of energy conservation design, so that energy conservation is implemented.2.3 The promotion of new technologies issueNew technology in the HVAC system for energy conservation provides a new direction. Such as ground source heat pump systems, solar cooling and heating system, not only to achieve efficient use of renewable energy, and can bring significant economic benefits, is worth promoting. However, as with any new technology, these new technologies are often high in cost, and the geographical conditions of use have certain limitations, and technically there are still many areas for improvement to improve. Therefore, new energy-efficient technologies, we should be according to local conditions, sum up experience, and actively promote.3. ConclusionHVAC systems saving energy in the building occupies a very important position, should attract enough attention to the designer. Designers should be from a design point of view fully into account the high and strict compliance with energy standards energy saving ideas to run through all aspects of the construction sector. Energy-saving technologies and renewable energy recycling, the Government and other relevant departments should support and vigorously promoted. And the design, construction, supervision, quality supervision, municipal administration and other departments should cooperate closely and pay close attention to implementing a cold, heat metering devices to collect tolls, so people really get benefit from energy efficient building, energy-saving construction and non-heating energy efficient building can not have the same charge standard. At the same time to raise public awareness of energy conservation, and vigorously promote the development of new energy-saving technologies to achieve sustainable development of society.References[1] "residential design standard" DBJ14-037-2006.[2] "Public Buildings Energy Efficiency Design Standards" DBJ14-036-2006.[3] "Technical Specification for radiant heating" JGJ142-2004.析暖通空调系统在建筑中的节能问题摘要经济的发展使人们对能源的需求不断增加,但是自然界的能源并不是取之不尽,用之不竭的。

附录C:外文翻译资料Article Source:Business & Commercial Aviation, Nov 20, 2000. 5-87-88 Interactive Electronic Technical Manuals Electronic publications can increase the efficiency of your digital aircraft and analogtechnicians.Benoff, DaveComputerized technical manuals are silently revolutionizing the aircraft maintenance industry by helping the technician isolate problems quickly, and in the process reduce downtime and costs by more than 10 percent.These electronic publications can reduce the numerous volumes of maintenance manuals, microfiche and work cards that are used to maintain engines, airframes, avionics and their associated components."As compared with the paper manuals, electronic publications give us greater detail and reduced research times," said Chuck Fredrickson, general manager of Mercury Air Center in Fort Wayne, Ind.With all the advances in computer hardware and software technologies, such as high quality digital multimedia, hypertext and the capability to store and transmit digital multimedia via CD-ROMs/ networks, technical publication companies have found an effective, cost-efficient method to disseminate data to technicians.The solution for many operators and OEMs is to take advantage of today's technology in the form of Electronic Technical Manuals (ETM) or Interactive Technical Manuals (IETM). An ETM is any technical manual prepared in digital format that has the ability to be displayed using any electronic hardware media. The difference between the types of ETM/IETMs is the embedded functionality and implementation of the data."The only drawback we had to using ETMs was getting enough computers to meet our technicians' demand," said Walter Berchtold, vice president of maintenance at Jet Aviation's West Palm Beach, Fla., facility.A growing concern is the cost to print paper publications. In an effort to reduce costs, some aircraft manufacturers are offering incentives for owners to switch from paper to electronic publications. With an average printing cost of around 10 cents per page, a typical volume of a paper technical manual can cost the manufacturer over $800 for each copy. When producing a publication electronically, average production costs for a complete set of aircraft manuals are approximately $20 per copy. It is not hard to see the cost advantages of electronic publications.Another advantage of ETMs is the ease of updating information. With a paper copy, the manufacturer has to reprint the revised pages and mail copies to all the owners. When updates are necessary for an electronic manual, changes can either be e-mailed to theowners or downloaded from the manufacturer's Web site.So why haven't more flight departments converted their publications to ETM/IETMs? The answer lies in convincing technicians that electronic publications can increase their efficiency."We had an initial learning curve when the technicians switched over, but now that they are familiar with the software they never want to go back to paper," said Fredrickson.A large majority of corporate technicians also said that while they like the concept of having a tool that aids the troubleshooting process, they are fearful to give up all of their marked-up paper manuals.In 1987, a human factors study was conducted by the U.S. government to compare technician troubleshooting effectiveness, between paper and electronic methodology, and included expert troubleshooting procedures with guidance through the events. Results of the project indicated that technicians using electronic media took less than half the time to complete their tasks than those using the paper method, and technicians using the electronic method accomplished 65 percent more in that reduced time.The report also noted that new technicians using the electronic technical manuals were 12-percent more efficient than the older, more experienced technicians. (Novices using paper took 15 percent longer than the experts.)It is interesting that 90 percent of the technicians who used the electronic manuals said they preferred them to the paper versions. This proved to the industry that with proper training, the older technicians could easily transition from paper to electronic media.Electronic publications are not a new concept, although how they are applied today is. "Research over the last 20 years has provided a solid foundation for today's IETM implementation," said Joseph Fuller of the U.S. Naval Surface Warfare Center. "IETMs such as those for the Apache, Comanche, F-22, JSTAR and V-22 have progressed from concept to military and commercial implementation."In the late 1970s, the U.S. military investigated the feasibility of converting existing paper and microfilm. The Navy Technical Information Presentation System (NTIPS) and the Air Force Computer- based Maintenance Aid System (CMAS) were implemented with significant cost savings.The report stated that transition to electronic publications resulted in reductions in corrective maintenance time, fewer false removals of good components, more accurate and complete maintenance data collection reports, reduction in training requirements and reduced system downtime.The problem that the military encountered was ETMs were created in multiple levels of complexity with little to no standardization. Options for publications range from simple page-turning programs to full-functioning automated databases.This resulted in the classification of ETMs so that the best type of electronic publication could be selected for the proper application.Choosing a LevelWith all of the OEM and second- and third-party electronic publications that are available it is important that you choose the application level that is appropriate for your operation.John J. Miller, BAE Systems' manager of electronic publications, told B/CAthat "When choosing the level of an ETM/IETM, things like complexity of the aircraft and its systems, ease of use, currency of data and commonality of data should be the deciding factors; and, of course, price. If operational and support costs are reduced when you purchase a full-functioning IETM, then you should purchase the better system."Miller is an expert on the production, sustainment and emerging technologies associated with electronic publications, and was the manager of publications for Boeing in Philadelphia.Electronic publications are classified in one of five categories. A Class 1 publication is a basic electronic "page turner" that allows you to view the maintenance manual as it was printed. With a Class 2 publication all the original text of the manual is viewed as one continuous page with no page breaks. In Class 3, 4 and 5 publications the maintenance manual is viewed on a computer in a frame-based environment with increasing options as the class changes. (See sidebar.)Choosing the appropriate ETM for your operation is typically limited to whatever is being offered on the market, but since 1991 human factors reports state the demand has increased and, therefore, options are expected to follow.ETM/IETM ProvidersCompanies that create ETM/IETMs are classified as either OEM or second party provider. Class 1, 3 and 4 ETM/IETMs are the most commonly used electronic publications for business and commercial operators and costs can range anywhere from $100 to $3,000 for each ETM/ IETM. The following are just a few examples ofETM/IETMs that are available on the market.Dassault Falcon Jet offers operatorsof the Falcon 50/50EX, 900/900EX and 2000 a Class 4 IETM called the Falcon Integrated Electronic Library by Dassault (FIELD). Produced in conjunction with Sogitec Industries in Suresnes Cedex, France, the electronic publication contains service documentation, basic wiring, recommended maintenance and TBO schedules, maintenance manual, tools manual, service bulletins, maintenance and repair manual, and avionics manual.The FIELD software allows the user to view the procedures and hot- link directly to the Illustrated parts catalog. The software also enables the user to generate discrepancy forms, quotation sheets, annotations in the manual and specific preferences for each user.BAE's Miller said most of the IETM presentation systems have features called "Technical Notes." If a user of the electronic publication notices a discrepancy or needs to annotate the manual for future troubleshooting, the user can add a Tech Note (an electronic mark-up) to the step or procedure and save it to the base document. The next time that or another user is in the procedure, clicking on the tech note icon launches a pop-up screen displaying the previous technician's comments. The same electronic transfer of tech notes can be sent to other devices by using either a docking station or through a network server. In addition, systems also can use "personal notes" similar to technical notes that are assigned ID codes that only the authoring technician can access.Requirements for the FIELD software include the minimum of a 16X CD-ROM drive,Pentium II 200 MHz computer, Windows 95, Internet Explorer 4 SP 1 and Database Access V3.5 or higher.Raytheon offers owners of Beech and Hawker aircraft a Class 4 IETM called Raytheon Electronic Publication Systems (REPS). The REPS software links the frame-based procedures with the parts catalog using a single CD-ROM.Raytheon Aircraft Technical Publications said other in- production Raytheon aircraft manual sets will be converted to the REPS format, with the goal of having all of them available by 2001. In addition Raytheon offers select Component Maintenance Manuals (CMM). The Class 1 ETM is a stand-alone "page-turner" electronic manual that utilizes the PDF format of Adobe Acrobat.Other manufacturers including Bombardier, Cessna and Gulfstream offer operators similar online and PDF documentation using a customer- accessed Web account.Boeing is one manufacturer that has developed an onboard Class 5 IETM. Called the Computerized Fault Reporting System (CFRS), it has replaced the F-15 U.S. Air Force Fault Reporting Manuals. Technologies that are currently being applied to Boeing's military system are expected to eventually become a part of the corporate environment.The CFRS system determines re-portable faults by analyzing information entered during a comprehensive aircrew debrief along with electronically recovered maintenance data from the Data Transfer Module (DTM). After debrief the technicians can review aircraft faults and schedule maintenance work to be performed. The maintenance task is assigned a Job Control Number (JCN) and is forwarded electronically to the correct work center or shop. Appropriate information is provided to the Air Force's Core Automated Maintenance System (CAMS).When a fault is reported by pilot debrief, certain aircraft systems have the fault isolation procedural data on a Portable Maintenance Aid (PMA). The JCN is selected on a hardened laptop with a wireless Local Area Network (LAN) connection to the CFRS LAN infrastructure. The Digital Wiring Data System (DWDS) displays aircraft wiring diagrams to the maintenance technician for wiring fault isolation. On completion of maintenance, the data collected is provided to the Air Force, Boeing and vendors for system analysis.Third party IETM developers such as BAE Systems and Dayton T. Brown offer OEMs the ability to subcontract out the development of Class 1 through 5 ETM/IETMs. For example, Advantext, Inc. offers PDF and IPDF Class 1 ETMs for manufacturers such as Piper and Bell Helicopters. Technical publications that are available include maintenance manuals, parts catalogs, service bulletins, wiring diagrams, service letters and interactive parts ordering forms.The difference between the PDF and IPDF version is that the IPDF version has the ability to search for text and include hyperlinks. A Class 1 ETM, when printed, is an exact reproduction of the OEM manuals, including any misspellings or errors. Minimum requirements for the Advantext technical publications is a 486 processor, 16 MB RAM with 14 MB of free hard disk space and a 4X CD-ROM or better.Aircraft Technical Publishers (ATP) offers Class 1, 2 and 3 ETM/ IETMsfor the Beechjet 400/400A; King Air 300/ 350, 200 and 90; Learjet 23/24/25/28/29/35/36/55; Socata TB9/10/20/21 and TBM 700A; Sabreliner 265-65, -70 and -80; andBeech 1900. The libraries can include maintenance manuals, Illustrated parts bulletins, wiring manuals, Airworthiness Directives, Service Bulletins, component maintenance manuals and structural maintenance manuals. System minimum requirements are Pentium 133 MHz, Windows 95 with 16 MB RAM, 25 MB free hard disk space and a 4X CD-ROM or better.Additional providers such as Galaxy Scientific are providing ETM/ IETMs to the FAA. This Class 2, 3 and 4 publication browser is used to store, display and edit documentation for the Human Factors Section of the administration."Clearly IETMs have moved from research to reality," said Fuller, and the future looks to hold more promise.The Future of Tech PubsThe use of ETM/IETMs on laptop and desktop computers has led research and development corporations to investigate the human interface options to the computer. Elements that affect how a technician can interface with a computer are the work environment, economics and ease of use. Organizations such as the Office of Naval Research have focused their efforts on the following needs of technicians: -- Adaptability to the environment.-- Ease of use.-- Improved presentation of complex system relationship.-- Maximum reuse and distribution of engineering data.-- Intelligent data access.With these factors in mind, exploratory development has begun in the areas of computer vision, augmented reality display and speech recognition.Computer vision can be created using visual feedback from a head- mounted camera. The camera identifies the relative position and orientation of an object in an observed scene, and the object is used to correlate the object with a three-dimensional model. In order for a computer vision scenario to work, engineering data has to be provided through visually compatible software.When systems such as Sogitech's View Tech electronic publication browser and Dassault Systemes SA's Enovia are combined, a virtual 3D model is generated.The digital mockup allows the engineering information to directly update the technical publication information. If a system such as CATIA could be integrated into a Video Reference System (VRS), then it could be possible that a technician would point the camera to the aircraft component, the digital model identifies the component and the IETM automatically displays the appropriate information.This example of artificial intelligence is already under development at companies like Boeing and Dassault. An augmented reality display is a concept where visual cues are presented to users on a head-mounted, see-through display system.The cues are presented to the technician based on the identification of components on a 3D model and correlation with the observed screen. The cues are then presented as stereoscopic images projected onto the object in the observed scene.In addition a "Private Eye" system could provide a miniature display of the maintenance procedure that is provided from a palm- size computer. Limited success hascurrently been seen in similar systems for the disabled. The user of a Private Eye system can look at the object selected and navigate without ever having to touch the computer. Drawbacks from this type of system are mental and eye fatigue, and spatial disorientation.Out of all the technologies, speech recognition has developed into an almost usable and effective system. The progression through maintenance procedures is driven by speaker-independent recognition. A state engine controls navigation, and launches audio responses and visual cues to the user. Voice recognition software is available, although set up and use has not been extremely successful.Looking at other industries, industrial manufacturing has already started using "Palm Pilot" personal digital assistants (PDAs) to aid technicians in troubleshooting. These devices allow the technician to have the complete publication beside them when they are in tight spaces. "It would be nice to take the electronic publications into the aircraft, so we are not constantly going back to the work station to print out additional information," said Jet Aviation's Berchtold.With all the advantages that a ETM/ IETM offers it should be noted that electronic publications are not the right solution all of the time, just as CBT is not the right solution for training in every situation. Only you can determine if electronic publications meet your needs, and most technical publication providers offer demo copies for your review.

外文资料及翻译
外文资料及译文原文:Television Video SignalsAlthough over 50 years old , the standard television signal is still one of the most common way to transmit an image. Figure 8.3 shows how the television signal appears on an oscilloscope. This is called composite video, meaning that there are vertical and horizontal synchronization (sync) pulses mixed with the actual picture information.These pulses are used in the television receiver to synchronize the vertical and horizontal deflection circuits to match the video being displayed. Each second of standard video contains 30 complete images, commonly called frames , A video engineer would say that each frame contains 525 lines, the television jargon for what programmers call rows. This number is a little deceptive because only 480 to 486 of these lines contain video information; the remaining 39to 45 lines are reserved for sync pulses to keep the television’s circuits synchronized with the video signal.Standard television uses an interlaced format to reduce flicker in the displayed image. This means that all the odd lines of each frame are transmitted first, followed by the even lines. The group of odd lines is called the odd field, and the group of even lines is called the even field. Since each frame consists of two fields, the video signal transmits 60 fields per second. Each field starts with a complex series of vertical sync pulses lasting 1.3 milliseconds. This is followed by either the even or odd lines of video. Each line lasts for 63.5 microseconds, including a 10.2 microsecond horizontal sync pulse, separating one line from the next. Within each line, the analog voltage corresponds to the gray scale of the image, with brighter values being in the direction away from the sync pulses. This place the sync beyond the black range. In video jargon, the sync pulses are said to be blacker than black..The hardware used for analog-to-digital conversion of video signals is called a frame grabber. This is usually in the form of an electronics card that plugs into a computer, and connects to a camera through a coaxial cable. Upon command from software, the frame grabber waits for the beginning of the next frame, as indicated by the vertical sync pulses. During the following two fields, each line of video is sampled many times, typically 512,640 or 720 samples per line, at 8bits per sample. These samples are stored in memory as one row of the digital image.This way of acquiring a digital image results in an important difference between the vertical and horizontal directions. Each row in the digital image corresponds to one line in the video signal, and therefore to one row of wells in the CCD. Unfortunately,the columns are not so straightforward. In the CCD, each row contains between about 400 and 800 wells (columns), depending on the particular device used. When a row of wells is read from the CCD, the resulting line of video is filtered into a smooth analog signal, such as in Figure 8.3. In other words, the video signal does not depend on how many columns are present in the CCD. The resolution in the horizontal direction is limited by how rapidly the analog signal is allowed to change. This is usually set at 3.2 MHz for color television, resulting in a rise time of about 100 nanoseconds, i.e, about1/500th of the 53.2 microsecond video line.When the video signal is digitized in the frame grabber, it is converted back into conclusions. However, these columns in the digitized image have no relation to the columns in the CCD. The number of columns in the digital image depends solely on how many times the frame grabber samples each line of video. For example, a CCD might have 800 wells per row, while the digitized image might only have 512 pixels (i.e columns) perrow.The number of columns in the digitized image is also important for another reason. The standard television image has an aspect ratio of 4 to 3, i.e. it is slightly wider than it is high. Motion pictures have the wider aspect ratio of 25 to 9. CCDs used for scientific applications often have an aspect ratio of 1 to 1, i.e , a perfect square. In any event, the aspect ratio of a CCD is fixed by the placement of the electrodes, and cannot be altered. However, the aspect ratio of the digitized image depends on the number of samples per line. This becomes a problem when the image is displayed, either on a video monitor or in a hardcopy. If the aspect ratio isn’t properly reproduced, the image looks squashed horizontally or vertically.The 525 line video signal described here is called NTSC (National Television Systems Committee), a standard defined way back in 1954. This is the system used in the United States and Japan. In Europe there are two similar standards called PAL (Phase Alternation by Line) and SECAM (Sequential Chrominance and Memory). The basic concepts are the same, just the numbers are different. Both PAL and SECAM operate with 25 interlaced frames per second, with 625 lines per frame. Just as with NTSC, some of these lines occur during the vertical sync, resulting in about 576 lines that carry picture information. Other more subtle differences relate to how color and sound are added to the signal.The most straightforward way of transmitting color television would be to have three separate analog signals, one for each of the three colors the human eye can detect: red, green and blue. Unfortunately, the historical development of television did not allow such a simple scheme. The color television signal was developed to allow existing blackand white television sets to remain in use without modification. This was done by retaining the same signal for brightness information , but adding a separate signal for color information. In video jargon, the brightness is called the luminance signal, while the color is the chrominance signal. The chrominance signal is contained on a 3.58 MHz carrier wave added to the black and white video signal. Sound is added in this same way, on a 4.5 MHz carrier wave. The television receiver separates these three signals, processes them individually, and recombines them in the final diplay.译文:关键词:核心,合成信号,电压耦合电视信号尽管已经拥有50年的历史了,电视信号依然是常用的传递信息的途径之一。
