稻草建筑材料在未来是否成为可能？露易丝·蒂克尔用稻草修房子并没有为《三只小猪》中的第一只带来任何好处，但是，如果巴斯大学的研究成果被建筑行业所接受的话，那么现代草砖将会成为未来的伟大设计。
说到一个草砖房子，你可能会联想到一个摇摇欲坠的窝棚，它漏水，发出吱吱的响声，随时都会垮塌在地，还带着类似农家的气息。
但是当你踏入BaleHaus的时候，一个被修建于巴斯大学校园里，看起来原始的当代房屋，将会令你吃惊地出展现在你面前，并且，你会发现你无法找到任何一缕稻草。
相反，你在一楼的走廊将会看到一个拥有两间卧室和一个浴室的倒置房子，和楼上一个通风的开放式的生活区。
这就像是从斯堪的纳维亚半岛抵达了萨默赛特郡。
这些由石灰做底泥制成的，干燥稻草捆，原来都是被紧紧捆住并放置于一系列预制好的木质矩形框架结构的墙中的，它们像乐高拼装玩具一样被嵌入一个叫做ModCell 的嵌板中。
这些“草屋”存在的问题似乎并不在于它们并不实用，而是人们意识到它们有点非主流，并且并不是特别耐用。
再加上，这样的草屋很难拿去获得抵押贷款。
巴斯大学BRE的建筑材料创新中心的主管Peter Walker 教授指出，稻草的好处在于：“它是便宜、易于广泛应用的良好绝缘体材料，它被用在房屋建筑上已经好几百年。
”作为整个世界的工业副产品——这些秸秆在谷物收获以后被留下——只要它们不分解，就仍然有效地吸收和固定大气中的碳。
对于建筑行业来说，当前所依赖的材料是无论在生产还是运输上都具有极高的能耗和碳消耗的嵌入式混凝土和砖——因此，稻草可以为解决温室气体排放这一问题提供一个友好的解决方案。
无论这个草屋看上去有多时髦，多现代化还是多环保，你仍然想要知道它是否会在雷电交加的暴风雨中被淋得湿透或者是否会因你打翻的蜡烛，而被被嗖嗖的火焰烧的精光。
Walker 教授和他的研究伙伴公布了他们的研究结果，Dr Katharine Beadle 花费了18个月的时间，通过一个详尽的危险因素清单去测试这个BaleHaus被腐蚀、烧毁、吹倒的可能，到目前为止，这个房子看来似乎是可靠的。

参考译文Unit 1课文A石油1油，和煤一样，存在于沉积岩中，而且可能由死去很长时间的生物有机体形成。
含有石油的岩石几乎都来源于海洋，所以形成石油的有机物一定是海洋生物，而不是树木。
2 石油，并不是来自于逐渐积聚的木质物质，而可能是来自于逐渐积聚的海洋生物的脂肪物质。
比如浮游生物：大量浮游在海水表层的单细胞生物。
3 有机物的脂肪物质主要由碳氢原子组成，因此并不需要太多的化学变化就可以形成石油。
生物有机体只需在缺氧的条件下沉积到海湾浅水处的淤泥里。
其脂肪不是分解腐烂，而是逐渐积聚，并在深层的淤泥里圈闭起来，进而经过细微的原子重组，最终形成石油。
4 油比水轻，呈液态，会经由上方覆盖的孔隙性岩石向上渗透，在地球上有些地区到达表层，古人将这些表层石油称为沥青、柏油或异庚烷。
在古代和中世纪，这些石油油苗常被看作药品而不是燃料。
5 当然，表层的油苗数量很少。
而石油油藏上方有时覆盖的是非孔隙性岩石。
石油向上渗透抵达该岩石，然后在岩石下方逐渐积聚形成油层。
若在上方的岩石上钻个孔，石油就可以通过该孔向上迁移。
有时压力过大，石油会向高空喷出。
1859年在宾夕法尼亚州，由埃德温·德雷克成功打出第一口井。
6 如果可以发现一个合适的地点（勘探人员已经识别出地下可能圈闭有石油的地层结构），那么就很容易抽取这一液体燃料，这要比派人到地下把大块的固体煤炭砍成小块要容易得多。
而且一旦获得石油，可以通过地上管道运输，而不必像煤一样，由运货车经过繁重的装卸任务来运输。
7 石油便于抽取，易于运输，促进了石油的应用。
石油可以蒸馏成不同的馏分，每种馏分均由特定大小的分子组成，分子越小，该馏分就越容易蒸发。
8 到19世纪下半叶，最重要的石油馏分是由中等大小的分子构成的煤油，它不易蒸发，被用于照明。
9 然而，到19世纪末人们研制出了内燃机。
内燃机是通过在汽缸里将空气与可燃气体混合，产生爆炸来提供动力的。
最便利的可燃气体是汽油——石油的又一馏分，由小分子构成，容易蒸发。

mobile and cellular radio移动和细胞广播in comparison to the relative stability and modest technical developments which are occurring in long haul wideband microwave communication systems there is rapid development and expanding deployment of new mobile personal communication system. These rang from wide coverage area pagers,for simple data message transmission,which employ common standards and hence achieve contiguous coverage over large geographical areas,such as all the major urban centres and transport routes in Europe,Asia or the continental USA.This chapter discusses the special channel characteristics of mobile systems and examines the typical cellular clusters adopted to achieve continuous communication with the mobile user.It then highlights the important properties of current,and emerging,TDMA and code division multiple access(CDMA), mobile digital cellular communication systems.Private mobile radioTerrestrial mobile radio works best at around 250 MHz as lower frequencies than this suffer from noise and interference while higher frequencies experience multipath propagation from buildings,etc,section 15.2.In practice modest frequency bands are allocated between 60MHz and 2GHz. Private mobile radio(PMR) is the system which is used by taxi companies,county councils,health authorities,ambulance services,fire services,the utility industries,etc,for mobile communications.PMR has three spectral at VHF,one just below the 88 to 108 MHz FM broadcast band and one just above this band with another allocation at approximately 170MHz.There are also two allocations at UHF around 450MHz. all these spectral allocations provide a total of just over 1000 radio channels with the channels placed at 12KHz channel spacings or centre frequency offsets. Within the 12khz wide channal the analogue modulation in PMR typically allows 7khz of bandwidth for the signal transmission.when further allowance is made for the frequency drift in the oscillators of these systems a peak deviation of only 2 to 3 khz is available for the speech traffic. Traffic is normally impressed on these systems by amplitude modulation or frequency modulation and again the receiver is of the ubiquitous superheterodyne design,Figure 1.4. A double conversion receiver with two separate local oscillator stages is usually required to achieve the required gain and rejection of adjacent channel signals.One of the problems with PMR receiver is that they are requiredto detect very small signals,typically—120dBm at the antenna output,corresponding to 0.2 uV,and,after demodulating this signal,produce ann output with perhaps 1W of audio equipment, the first IF is normally at10.7MHz and the second IF is very orten at 455KHz . unfortunately,with just over 1000 available channels for the whole of the UK and between 20000and30000issued licences for these systems,it is inevitable that the average busuness user will have to share the allocated channel with other companies in their same geographical area.There are various modes of operation for mobile radio communications networks, the simplest of which is singal frequency simplex. In simplex communication, traffic is broadcast, or one way. PMR uses half duplex(see later Table 15.3) where, at the end of each transmission period, there is a handover of the single channel to the user previously receiving, in order to permit them to reply over the same channel. This is efficient in that it requires only one frequency allocation for the communication link but it has the disadvantage that all units canhear all transmissions provided they are within rage of the mobile and frequencies are allocated for the transmissions. One frequency is used for the forward or downlink, namely base-to-mobile communications. This permits simultaneous two-way communication and greatly reduces the level of interference, but it halves other’s transmissions, which can lead to contention with two mobiles attempting to initiate a call, at the same time, on the uplink in a busy syetem.Although PMR employs relatively simple techniques with analogue speech transmission there have been many enhancements to these systems over the years . Data transmission is now in widespread use in PMR systems using FSK modulation. Data transmission also allows the possibility of hard copy graphics output and it gives direct access to computer services such as databases, etc. Data prembles can also be used, in a selective calling mode, when initiating a transmission to address a special receiver and thus obtain more privacy within the system.15.4.5 Trunked radio for paramilitary use集群无线电的军事使用Another related TDMA mobile radio standard is the European trunked radio(TETRA)network which has been developed as part of the public safety radio communications service(PSRCS) for use by police, utilities, customs office, etc. TETRA in fact is part of wider international collaborations for paramilitary radio use.In these portable radios there is a need for frequency hopping (FH) to give an antieavesdropping capability and encryption for security of transmission to extend military mobile radio capabilities to paramilitary use, i.e. for police, customs and excise offices, etc. these capabilities are included in the multiband interteam radio for the associated public safety communications office in the USA while Europe has adopted the TETRA standard.TETRA is essentially the digital TDMA replacement of the analogue PMR systems. The TETRA standard has spectrum allocations of 380 to 400 and 410 to 430MHz, with the lower band used for mobile transmissions and the upper band for base station use. TETRA mobile have 1 W output power and the base stations 25 W using error with the data throughput rate varying, to meet the required quality of service. TETRA can accommodate up to four users each with a basic speech or data rate of 7.2kbit/s. with coding and signaling overheads, the final transmission rate for the four-user slot is 36 kbit/s. this equipment is large and more sophisticated than a commercial cell phone, and it sells for a very much higher price becase the production runs are much small. However, its advanced capabilities are essential for achieving paramilitary communications which are secure from eavesdropping.15.5 Code division multiple accessAnalogue communication systems predominantly adopt frequency division multiple access (FDMA), where each subscriber is allocated a narrow frequency slot within the available channel. The alternative TDMA(GSM) technique allocates the entire channel bandwidth to a subscriber but constrains the subscriber but constrains the subscriber to transmit only regular short bursts of wideband signal. Both these accessing techniques are well established for long haulterrestrial, satellite and mobile communications as they offer very good utilization of the available bandwidth.15.5.1The inflexibility of these coordinated accessing techniques has resulted in the development of new systems based on the uncoordinated spread spectrum concept. In these systems the bits of slow speed data traffic from each subscriber are deliberately multiplied by a high chip rate spreading code, forcing the low rate (narrowband data signal) to fill a wide channel bandwidth.15.7.2 3G systemsThe evolution of the third generation (3G)system began when the ITU produce the initial recommendations for a new universal mobile telecommunications system(UMTS)[www.] The 3G mobile radio service provides higher data rate services ,with a maximum data rate in excess of 2Mbit/s, but the achievable bit rate is linked to mobility. Multimedia applications encompass services such as voice, audio/video, graphics, data, Internet access and e-mail. These packet and circuit switched services have to be supported by the radio interface and the network subsystem.Several radio transmission technologies(RTT) were evaluated by the ITU and adopted into the new standard, IMT-2000. the European standardization body for 3G, the ETSI Special Mobile Group, agreed on a radio access scheme for 3G UMTS universal terrestrial radio access(UTRA) as an evolution of GSM. UTRA consists of two modes : frequency division duplex(FDD) where the uplink and downlink are transmitted on different frequencies; and time division duplex(TDD) where the uplink and downlink are time multiplexed onto the same carrier frequency. The agreement assigned the unpaired bands (i.e. for UTRA TDD ). TD-CDMA is a pure CDMA based system. Both modes of UTRA have been harmonised with respect to basic system parameters such as carrier spacing, chip rate and frame length to ensure the interworking of UTRA with GSM.The 3G proposal were predominantly based wideband CDMA(WCDMA) and a mix of FDD and TDD access techniques. WCDMA is favoured for 3G in poor propagation environments with a mix of high modest speed data traffic. It is generally accepted that CDMA is the preferred accesstechnique and, with the increase in the data rate, then the spreading modulation needs to increase to wideband transmission.WCDMA is based on 3.84Mchip/s spreading codes with spreading ratio, i.e. , K values, of 4-256 giving corresponging data ratas of 960-15 kbit/s. the upper FDD uplink band I from 1920-1980 MHz is paired with a 2110-2170 MHz downlink. In addition uplink bands II & III at 1850-1910 MHz and 1710-1785 MHz are also paired, respectively, with 1930-1990 MHz and 1805-1880 MHz allocations. the system is configured on a 10 ms frame with 15 individual slots to facilitate TDD as well as FDD transmissions. TDD is more flexible as time-slots can be dynamically reassigned to uplink and downlink functions, as required for asymmetric transfer of large files or video on demand traffic. 3G WCDMA systems use an adaptive multirate speech coder with encoded rates of 4.75-12.2 kbit/s. receivers commonly use the easily integrated direct conversion design, in place of the superheterodyne design . receiver sensitivities are typically -155dBm.The 3GPP2 standard aims to achieve a wide area mobile wireless packet switched capability with CDMA2000 1×EV DO revision A (sometimes called IS-856A). Here 1×refers to the single carrier 1.25 Mchip/s system. It achieves a 3.1 Mbit/s downlink and a delay sensitive services. The 3GPP standard has gone through many release with R4 in 2001 which introduced packet data services and R6 in 2005 to further increase the available data transmission rate . R6 pioneers the use of high-speed downlink packet access and multimedia broadcast multicast services which offer reduced delays and increased uplink data rates approaching 6 Mbit/s.In parallel with the European activities extensive work on 3G mobile radio was also performed in Japan. The Japanese standardisation body also chose WCDMA, so that the Japanese and European proposals for the FDD mode were already aligned closely. Very similar concepts have also been adopted by the North American standardization body.In order to work towards a global 3G mobile radio standard, the third generation partnership project(3GPP), consisting of members of the standardization bodies in Europe, the USA, Japan, Korea and China, was formed. It has merged the already well harmonized proposals of the regional standardization bodies to work on a common 3G international mobile radio standard, still called UTRA. The 3GPP Project 2(3GPP2), on the other hand, works towards a 3G mobile radio standard based on cdmaOne/IS-95 evolution, originally called CDMA2000.比起相对稳定、适度的技术发展是发生在宽带微波通信系统,有长期快速发展和扩大部署的新的移动个人通讯系统。

科技英语的特点及翻译
科技英语的特点与翻译一、科技英语的特点科技英语（English for science and technology，EST）指与用于科学和技术交流方面的英语口语和书面语。
作为一种重要的英语语体，其特点主要体现在以下几个方面。
1、词汇方面大量使用专业词汇、复合词、缩略词及利用前后缀构成的派生词。
专业词汇意义专一，用来表示明确的含义。
科技词汇多源于希腊语和拉丁语，是因为这两种语言作为英语的重要来源，是世界上成熟最早和最完备的语言中的两种，词汇不再发生词形、词义上的变化，具有稳定性。
2、句子方面多使用长句和被动语态，大量使用名词化结构（nominalization）和非限定动词。
另外，各种成份（如介词短语、形容词及其短语、副词、分词及从句等）作定语并后置，多使用It…that…结构句型、被动结构句型、as结构句型、分词短语结构句型和省略句结构句型等常用句型。
名词化结构有利于行文简洁、表达客观、内容确切，也可使所含信息量增大，尤其是科技英语强调存在的事实，而非个别行为。
不定式短语、-ing分词短语和-ed分词短语这三种非限定动词形式具有齐备的语法功能，可代替各种从句，这样既可缩短句子，行文简练，结构紧凑，又比较醒目。
3、形态方面科技英语在时态运用上有限，多用过去时和现在时。
尤其是多用一般现在时，以表述无时间性的科学定义、定理、公式、现象、过程等。
另外，科技英语多用逻辑性语法词（logical grammatical operators），如表示原因的如because (of)、due (owing) to、as (a result of)、caused by、for等，表示语气转折的如but、however、nevertheless、otherwise、yet等，表示逻辑顺序的如so、therefore、thus、furthermore、moreover、in addition to等。
4、文体方面科技英语注重行文的连贯（coherence）、清晰（clarity）、流畅（fluency），避免行文晦涩、表露个人感情、过多运用修辞手法等。

它将拥有一个中央处理器、磁盘存储器、制图硬件和某种直观的计算机用户界面。
如果再在加上一个无线鼠标和键盘，这个家庭娱乐系统看起来便很像是一台个人电脑。
人们会大量购买和使用这些系统吗？当然会。
他们会认为这种系统就是电脑吗？也许不会。
根据格特纳信息咨询公司（一家美国研究公司）的统计，世界计算机业在2002年销售了第10亿台个人电脑，而还有10亿台电脑预计在此后的6年中生产出来。
第一批的10亿台电脑几乎都是传统的台式机和笔记本电脑，但第二批的10亿台电脑将会明显不同，人们对它们进行了尽可能的完善，使它们能更好的按照人们的期望运作，例如便签大小的电脑，开会时我们可以用它来做笔记，或是躺在床上阅读电子邮件；娱乐型电脑，用来在客厅电视上播放音乐和电影；袖珍型电脑，用它无论在哪都能与他人保持联系。
除此之外，还有各种数量庞大的嵌入式计算机（如在手机、加油站和零售终端设备中使用的计算机），在功能和复杂性方面正迅速赶上台式电脑。
据估计，有意无意美国人每天会接触到大约150个嵌入式计算机系统。
这些系统使用了现在生产的90% ％的微处理器，它们将不可避免地呈现出更多个人电脑的特点，而且能够与传统PC机进行无缝对接。
这一系统将无处不在。
根据半导体工业协会的调查，在2001年，世界芯片业为地球上的每位个男士人，女士妇女和儿童生产了大约6千万个晶体管，这一数字到2010年将上升为10亿。
与此同时，今天的多功能PC机将继续在大多数人的生活中发挥重要（而且是越来越重要）的作用，但其中心地位将体现在今天大部分人不认为是“电脑”的各类智能设备中。

The end of e-mail ageEmail has had a good run as king of communications. But its reign is over.In its place, a new generation of services is starting to take hold -- services like Twitter and Facebook and countless others vying for a piece of the new world. And just as email did more than a decade ago, this shift promises to profoundly rewrite the way we communicate -- in ways we can only begin to imagine.We all still use email, of course. But email was better suited to the way we used to use the Internet -- logging off and on, checking our messages in bursts. Now, we are always connected, whether we are sitting at a desk or on a mobile phone. The always-on connection, in turn, has created a host of new ways to communicate that are much faster than email, and more fun.Why wait for a response to an email when you get a quicker answer over instant messaging? Thanks to Facebook, some questions can be answered without asking them. You don't need to ask a friend whether she has left work, if she has updated her public'status' on the site telling the world so. Email, stuck in the era of attachments, seems boring compared to services like Google Wave, currently in test phase, which allows users to share photos by dragging and dropping them from a desktop into a Wave, and to enter comments in near real time.Little wonder that while email continues to grow, other types of communication services are growing far faster. In August 2009, 276.9 million people used email across the U.S., several European countries, Australia and Brazil, according to Nielsen Co., up 21% from 229.2 million in August 2008. But the number of users on social-networking and other community sites jumped 31% to 301.5 million people.'The whole idea of this email service isn't really quite as significant anymore when you can have many, many different types of messages and files and when you have this all on the same type of networks,' says Alex Bochannek, curator at the Computer History Museum in Mountain View, Calif.So, how will these new tools change the way we communicate? Let's start with the most obvious: They make our interactions that much faster.Years ago, we were frustrated if it took a few days for a letter to arrive. A couple of years ago, we'd complain about a half-hour delay in getting an email. Today, we gripe about it taking an extra few seconds for a text message to go through. In a few months, we may be complaining that our cellphones aren't automatically able to send messages to friends within a certain distance, letting them know we're nearby. (A number of services already do this.)These new services also make communicating more frequent and informal -- more like a blog comment or a throwaway aside, rather than a crafted email sent to one person. No need to spend time writing a long email to your half-dozen closest friends about how your vacation went. Now those friends, if they're interested, can watch it unfold in real time online. Instead of sending a few emails a week to a handful of friends, you can send dozens of messages a day to hundreds of people who know you, or just barely do.Consider Twitter. The service allows users to send 140-character messages to people who have subscribed to see them, called followers. So instead of sending an email to friends announcing that you just got a new job, you can just tweet it for all the people who have chosen to 'follow' you to see. You can create links to particular users in messages by entering @ followed by their user name or send private 'direct messages' through the system by typing d and the user name.Facebook is part of the trend, too. Users post status updates that show up in their friends' 'streams.' They can also post links to content and comment on it. No in-box required.Dozens of other companies, from AOL and Yahoo Inc. to start-ups like Yammer Inc., are building products based on the same theme.David Liu, an executive at AOL, calls it replacing the in-box with 'a river that continues to flow as you dip into it.'But the speed and ease of communication cut both ways. While making communication more frequent, they can also make it less personal and intimate. Communicating is becoming so easy that the recipient knows how little time and thought was required of the sender. Yes, your half-dozen closest friends can read your vacation updates. But so can your 500 other 'friends.' And if you know all these people are reading your updates, you might say a lot less than you would otherwise.Another obvious downside to the constant stream: It's a constant stream.That can make it harder to determine the importance of various messages. When people can more easily fire off all sorts of messages -- from updates about their breakfast to questions about the evening's plans -- being able to figure out which messages are truly important, or even which warrant a response, can be difficult. Information overload can lead some people to tune out messages altogether.Such noise makes us even more dependent on technology to help us communicate. Without software to help filter and organize based on factors we deem relevant, we'd drown in the deluge.Perhaps the biggest change that these email successors bring is more of a public profile for users. In the email world, you are your name followed by a 'dot-com.' That's it. In the new messaging world, you have a higher profile, packed with data you want to share and possibly some you don't.Such a public profile has its pluses and minuses. It can draw the people communicating closer, allowing them to exchange not only text but also all sorts of personal information, even facial cues. You know a lot about the person you are talking to, even before you've ever exchanged a single word.电子邮件作为通信之王经历了飞速发展。

What Is Multimedia?
Multimedia means that computer information can be represented through audio, graphics, images, video, and animation in addition to traditional media, such as texts and drawings. All of the technologies make computers more interesting and much easier to use. The most important technologies are as the following. CD－Rom is an optical technology that is used to make compact disks for CD stereo Systems. It has now been adapted to store data for computers．CD disk is an optical disc, on which data is recorded as a set of dips in the surface．When a laser beam shines across the dips, the reflected distortion represents the data. Optical disc has a 600 megabyte capacity and is well suited for the computer applications needing the vast storage．The playback effect of optical discs for music is perfect，no hiss and crackle as with other photo-records. A computer system must have a CD drive that is designed to read the disks and translate the data into a form it can process. CD disks can store huge volumes of data and are very useful for reference materials―an encyclopedia, for example. However, as the name（read-only memory）implies, CD disks cannot be written on or changed in any way． Musical Instrument Digital Interface, or MIDI is a communication interface provided for every synthesizer made today. It provides a standard that allows products by different companies to communicate with each other. MIDI’s original purpose is to allow a musician to control several synthesizers from one keyboard rather than connect a number of keyboard-equipped synthesizers, to produce the multilayered sound. The MIDI standard
05 Learning Objectives
In this unit you should get familiar with:
Multimedia
the concept of multimedia the components of multimedia the main application of multimedia in reality the future of multimedia in the world
Exercises:
1. Answer the following questions briefly according to the text.
① In what way can multimedia make the computer interesting and easier to use? ② What is CD-ROM and what usage does it have? ③ What does ADC stand for? ④ How many channels can Musical Instrument Digital Interface provide when you play music ? ⑤ How is virtual reality created by computer?
provides for 16 channels. You can assign each channel to a specific synthesizer or synthesizer voice. If you record a sequence and assign it to channel 5, for example, only an instrument set to listen on channel 5 plays back the sequence. This feature enables MIDI networks to sound like orchestras． An audio（sound）wave is a one-dimensional acoustic（pressure） wave. When an acoustic wave enters the ear， the eardrum vibrates， causing the tiny bones of the inner ear to vibrate along with it， and sending nerve pulses to the brain． These pluses are perceived as sound by the listener. Audio waves can be converted to digital form by an ADC （analog digital converter). An ADC takes an electrical voltage as input and generates a binary number as output． Music，of course，is just a special case of general audio，but an important one．The representation，processing，storage, and transmission of such audio signals are a major part of the study of multimedia systems. In fact, virtual reality is exploiting software and hardware of the computer to generate a simulation of an environment, such as an easeful classroom，a breathtaking action and so on. In such a simulated environment, one would have an immersed sense and undergo all experiences in the space．His or her various senses in the realistic world would be replaced with a series of new electric stimuli. The cyberspace is regarded as a goal of future virtual reality．
