第三篇：科技英語閱讀翻譯

Before any evidence can be introduced in support of the topic at hand, the definition of invention must be established.Legally, an invention is a new, useful, and non-obvious process, machine, or product.Maurice Fabre, author of A History of Land

Transportation(1963), offered an interesting take on the automobile and its inventor.“who, for that matter ,can say who invented the automobile? Was it Cugnot with his lumbering 'fardier' of 1769? Was it Trevithick with his steam carriage of 1801, or Benz or Daimler with their first successful internal combustion gasoline engine cars of 1886?It depends what you mean by an automobile.” in the year 2001, what do we consider the automobile to be ? I invite the reader to take a minute to look out the window.I see a street lined with cars.Many of these cars possess similar shapes and sizes.In fact, some of them are the same make and model, only different colors.What does this tell us about the modern automobile? The modern automobile is not a single vehicle;it is a collection of millions of cars designed for utilization by a mass market.In fact, we could argue that the modern automobile is a giant technological system that entails a way of life.Entire economies depend on this automobile.Engineers design the components, machinists manufacture the components, assemblers assemble the components into complete systems, truck drivers deliver the assembled product, and salesmen sell the product to the masses.This brief description does not even account for the office

workers who handle logistics and maintain financial accounts, or the separate companies that mine raw materials or design and manufacture the needed machine tools.What would the economy of the United States be like without the modern automobile?

Obviously, the modern automobile and self propelled vehicle are necessarily the same.翻譯：在任何證據(jù)被介紹來支持這個(gè)主題以前，必須建立發(fā)明的定義。從法律意義上來說,一項(xiàng)發(fā)明是一個(gè)新的、有用的創(chuàng)造性工藝、機(jī)器、或產(chǎn)品。Maurice Fabre的《陸運(yùn)的歷史》(1963)提供了一個(gè)有趣的汽車和其發(fā)明者?！瓣P(guān)于那件事,誰可以說是誰發(fā)明了汽車嗎?是1769年笨拙的柯諾特嗎? 這是1801年特里維西克他的蒸汽運(yùn)輸車,或奔馳或戴姆勒的首次成功或1886年克萊斯勒的內(nèi)部燃燒汽油引擎的汽車嗎?那要看你怎么說一輛汽車?！霸?001年,我們認(rèn)為什么是汽車呢?我請讀者花一分鐘的時(shí)間往窗外看。我看到了街兩旁的汽車。這些汽車具有相似的形狀和大小。事實(shí)上,他們中的一些是相同的廠牌和型號,只是不同的顏色。這個(gè)是在告訴我們什么是關(guān)于現(xiàn)代的汽車嗎?現(xiàn)代汽車不是單獨(dú)的車輛,它是一個(gè)收集數(shù)百萬輛汽車設(shè)計(jì)利用的大規(guī)模市場。事實(shí)上,我們可以認(rèn)為在我們的生活方式中現(xiàn)代汽車是一個(gè)巨大的技術(shù)系統(tǒng),整個(gè)經(jīng)濟(jì)依賴這種汽車。工程師設(shè)計(jì)組件,機(jī)械師制造部件,組裝成完整的系統(tǒng)組裝元件,卡車司機(jī)提供產(chǎn)品的組裝、銷售人員賣產(chǎn)品到群眾。這一簡單的描述甚至占用不了上班族們處理物流和維護(hù)金融帳戶或者單獨(dú)的的礦業(yè)公司開采原材料或設(shè)計(jì)和制造所需的工具的時(shí)間。如果沒有現(xiàn)代汽車美國的經(jīng)濟(jì)將會怎么樣呢？顯然，現(xiàn)代汽車和自行式車輛必須是一樣的。

第四篇：英語科技論文翻譯

3G TECHNOLOGY Abstract The 21 century is an ages of the information economy, being the 3G TECHNOLOGY of representative technologies this ages, will be at very fast speed develop soon in continuously creatively, and will go deep into the people's work, life and study.Therefore, control this technology and then seem to be more to deliver the importance.Now I mainly introduce some knowledge of the 3G TECHNOLOGY.Keywords GPRS, TD-SCDMA，WCDMA , EDGE ,CDMA2000 , WAP , SYMBIAN G, the third Generation, known as the Chinese meaning is refers to the third Generation of digital communication.The growth of the global 3G was rapidly in recent years.From 2002 to 2008, the 3 G operators have been gradually from the original is pale and management to the accelerated development.By June 2008, global 3 G users accumulative total up to 709 million, the total 84 countries and regions issued 3 G licenses, including effective certificate for 249 copies.Our country of 3 G development is relatively later than the advanced countries.In 2009, China was officially forward 3 G time.In the economic crisis of the downturn state，China's ministry of information industry issued three third generation mobile communication(3 G)license for China mobile, China telecom and China Unicom.China Mobile use our country with independent intellectual property rights of the 3 G standard TD-SCDMA , China Telecom get CDMA2000 license and China Unicom WCDMA license.2009 as China 3 G formal first commercial.Although the technology behind 3G may seem complicated, the ways in which 3G will affect all of our lives are easy to imagine.Just imagine having a combined camera, video-camera, computer, stereo, and radio included in your mobile phone.Rich-media information and entertainment will be at your fingertips whenever you want anywhere there is a wireless network.Mobile communication is moving from simple voice to rich media, where we use more of our senses to intensify our experiences.But not all of this will happen at once.3G is an evolution to a communications ideal that no one completely understands yet.What we do know is that mobile multimedia will hit the Japanese markets in 2001, and Europe and North America will follow soon after.3G brings together high-speed radio access and IP-based services into one, powerful environment.The step towards IP is vital.IP is packet-based, which in simple terms, means users can be “on line” at all times, but without having to pay until we actually send or receive data.The connectionless nature of IP also makes access a lot faster: file downloads can take a few seconds and we can be connected to our corporate network with a single click.3G introduces wideband radio communications, with access speeds of up to 2Mbit/s.Compared with today's mobile networks, 3G will significantly boost network capacityAt home 3G is going to affect our home and social lives in many ways.The services that 3G enables will help us to manage our personal information, simplify tasks such as grocery shopping, make better use of our time and offer services that are just fun to use.Operators will be able to develop myriad new service opportunities to attract and retain new customers.Here are some examples:

· You're sitting on a train and use this “dead” time to log on to your bank account, check your balance and pay a few billsAt work

3G will not just support the needs of businesspeople who travel a lot, but will also help new, flexible working practices, such as home-working and remote access to corporate networks outside traditional working hours.Businesspeople are often high-volume airtime users, so they represent a big opportunity for mobile operators.Here are some examples:

·

At work you receive a message from your “smart” refrigerator at home.The message tells you that certain items need restocking and an order has already been prepared for the local grocery store, which you can approve, so that your groceries are ready to collect on the way home.·

You are on the road, and urgently need to discuss a draft presentation with a number of colleagues back in the office.Pulling into a service station, you use your 3G device to hold a telephone conference with your colleagues and, at the same time, you can all view the draft presentation and make changes on line.·

A maintenance engineer is repairing some equipment on a client's premises and hits a problem.Using his 3G device, he contacts his department and downloads a demonstration video that guides him through the repair process.TECHNOLOGY 3G brings together two powerful forces: wideband radio communications and IP-based services.Together, these lay the groundwork for advanced Mobile Internet services, including personalized portals, “infotainment”, mobile commerce and unified messaging-encompassing high-speed data, superior quality voice and video and location-based services.Making 3G a reality depends on technology developments in different areas.These include

amendments to the radio interface to support wideband communications and in the core network.Supporting technologies, such as WAP and Bluetooth, also have an important role to play.This section provides a brief overview of some of the main technologies and developments involved.Ericsson supports all of these technologies and has played an active role in their development.·GPRS General Packet Radio Service(GPRS)is an enhancement to existing GSM and TDMA networks that introduces packet data transmission, enabling “always on” mobility.This means that users can choose to be permanently logged on to e-mail, Internet access and other services, but do not have to pay for these services unless sending or receiving information.When EDGE is added to GPRS, these data rates will increase up to 384kbit/s.GPRS will be implemented by adding new packet data nodes and upgrading existing nodes to provide a routing path for packet data between the mobile terminal and a gateway node.The gateway node will provide interworking with external packet data networks for access to the Internet and intranets.Benefits:

·Faster data speeds and “always on” mobility ·Almost instantaneous connection set-up

·Connection to an abundance of data sources around the world, through support for multiple protocols, including IP

·A step towards full 3G services.·TD-SCDMA All called Time Division-Synchronous CDMA , this standard is formulated by mainland China alone the 3 G standard.On June 29, 1999, the China telecom science and technology and telecommunications research institute(Datang Telecom)to the ITU, but technical invention father put forward in Siemens AG.TD-SCDMA has the characteristics of low radiation, known as the green 3 G.This standard will intelligent wireless, synchronous CDMA and software radio today the international leading technology into which, in spectrum use efficiency, the business support for flexibility, frequency flexibility and cost, and other aspects of the unique advantages.In addition, because of the huge market in China, the standard by the major telecommunications equipment manufacturer to the attention of the world, more than half of the equipment factory now announced that can support TD-SCDMA standards.This standard is made after 2.5 of the intermediate links, and the generation of directly to the 3 G transition, so it is suitable to GSM system to 3 G to upgrade.Military communication network is the core of TD-SCDMA task.·WCDMA

Wideband Code Division Multiple Access(WCDMA)is a wideband radio technique that provides far higher data rates than other radio techniques available today, up to 2Mbit/s, and highly efficient use of radio spectrum.The higher bandwidth that WCDMA provides will deliver the full potential of 3G.For example，WCDMA allows simultaneous access to several voice, video and data services at once.WCDMA is fully compliant with IMT-2000 and is the air interface technology for standards in the 2GHz bandwidth(the IMT-2000 core band), known as UMTS(Universal Mobile Telecommunication System)in Europe and ARIB(Association of Radio Industry Businesses)in Japan.Ericsson has been at the forefront of WCDMA development.The company delivered an experimental WCDMA system to NTT DoCoMo in Japan back in 1998.Ericsson has also set up WCDMA test systems around the world.At 2000, Ericsson announced its first family of WCDMA base stations.·EDGE

Enhanced Data Rates for Global Evolution(EDGE)enables GSM and TDMA operators to offer 3G services using existing network frequencies.By making changes and additions to standardization of evolutionary phases of the air interface and the backbone networks, as well as the migration to ALL-IP and multimedia networks.·CDMA2000 CDMA2000 is a decidedly efficient 3G standard for the delivery of high bandwidth data and high capacity voice services.The evolution of the cdma2000 standard will enable mobile systems to offer data throughputs of 2 Mbit/sec and beyond.The higher bandwidth that cdma2000 provides will deliver the full potential of 3G.For example, cdma2000 also allows simultaneous access to several voice, video and data services at once.CDMA2000 is fully compliant with IMT-2000 requirements for 3G.CDMA2000 will be implemented in the existing frequency bands of CMDA and TDMA at 800 and 1900 MHz, as well as in new spectrum at 2GHz in Japan.Ericsson is a leader in cdma2000 development, and a key driver in the standardization of evolutionary phases of the air interface and the backbone networks, as well as the migration to ALL-IP and multimedia networks.·Bluetooth

Bluetooth is an open standard for two-way, short-wave radio communications between different devices.It marks the end of cables and cords between mobile phones, palmtops, portable PCs and printers, for example.Furthermore, Bluetooth enables information between such devices to be synchronized.Diary information held on a PDA can be updated automatically when within range of a Bluetooth-enabled PC.Bluetooth is also going to be important for machine-to-machine communicationshundreds of companies are members of the worldwide WAP Forum。The latest version of the WAP standard, WAP 1.2.1, has recently been launched.Our dedicated WAP consutants are ready to assist operators and service providers sharpen their competitive edge.They help today's businesses adapt to the new economy and create cost-effective, innovative ways to communicate with customers.What will 3G give us

People will enjoy the 3G time what services it provide, the image of that, 3G is video conference on that plane;3G is patients receive timely assistance of medical experts;3G is fans will not miss the NBA basketball game;3G is to share with friends your beautiful vacation in Hawaii.· more and more 3G video phone

All along, we use QQ, MSN chat with friends remotely.As the mobile data transfer rate, image processing, transmission, mainly the acceptance of such display devices makes mobile video chat stranded.3G time to rely on high-speed 3G data transmission network, which 3G mobile phone users can “face to face” conversation.Through mobile video, As far away from the mother via cell phone together, were falling through the mobile phone lovers can meet again.·3G Push into the mobile phone shopping blowout Use the mobile internet shopping is a new way to shop, mobile shopping not only will be able to let consumer buy goods but also makes the satisfaction convenient for consumers to pick and choose goods compared with the constant.With the improvement of China's 3G network , more and more users will choose to phone shopping patterns.China's mobile phone shop will grow rapidly in a period.Online businesses not only include clothing, books, cell phones, toys, audio-visual products and other daily goods put on the network shelf, cars, laptop computers, jewelry and other luxury goods are also options for the list.One need only log out of 3G mobile phone shopping website of product information, we can buy our favorite items.Online shopping is not only cheaper than the mall , better able to send home delivery.If not satisfied can return on schedule, on-line business integrity committed to ensuring that the consumer's shopping safety.·Broadband Internet access to mobile phones to be a “small computer” Although China has just begun the road to 3G, broadband internet access business has been a bright spot, we can send and receive voice messages on the phone, write a blog, chat, search, download and so on, as well as top-notch services such as online games, mobile navigation, online chat and so on.·the key to the Mobile Office-OA system Although compared with traditional office, automation system greatly improves the working efficiency.However, the limitations of the region's OA system is limited to local area network applications, this office brings to enterprises a lot of inconvenience.Mobile office can keep in touch with units and complete work in anytime and at anywhere.3G mobile phones can download and install office, java and other office software, office software and hardware will be the traditional “compression” in the palm of a large mobile phone.·LCD TVs will be included in Mobile TV Mobile TV is to use with the operating system and streaming video-enabled smart phones to watch TV business.It is a multimedia that use CMMB technology, whether it is GPRS mobile phone or CD-MA1X phone, need to be equipped with mobile terminal operating system to install the appropriate player software.TV programs from the corresponding mobile communication company or by the corresponding SP to organize and deliver.Despite the development of a thriving scene 3G, but because mobile streaming media software, smooth video images and other technical aspects of picture quality there are some problems, Mobile TV strides also takes some time.3G技術(shù)

3G，全稱為3rd Generation，中文含義就是指第三代數(shù)字通信。全球3G近年來快速成長，從2002年到2008年，全球3G運(yùn)營商已經(jīng)逐步從最初的慘淡經(jīng)營轉(zhuǎn)為現(xiàn)在的加速發(fā)展，截止2008年6月，全球3G用戶累計(jì)已達(dá)到7.09億，全球共有84個(gè)國家和地區(qū)發(fā)放了3G許可證，其中有效證為249張。

我國3G發(fā)展相對先進(jìn)國家比較晚，2009年我國才正式邁進(jìn)3G時(shí)代，在經(jīng)濟(jì)危機(jī)低迷的狀態(tài)下，2009年1月7日，中國工業(yè)和信息化部為中國移動、中國電信和中國聯(lián)通發(fā)放3張第三代移動通信（3G）牌照。中國移動使用我國具有自主知識產(chǎn)權(quán)的3G標(biāo)準(zhǔn)TD-SCDMA，中國電信獲得CDMA2000牌照，中國聯(lián)通獲得WCDMA牌照。2009年成為中國3G正式商用年。

雖然在 3 G 后面的技術(shù)可能很復(fù)雜, 但是3 G 將會在我們生活中產(chǎn)生的影響是我們可以想象的。僅僅想像在你的行動電話中加入照相機(jī)、攝像機(jī)、計(jì)算機(jī)、音響以及收音機(jī)功能。這樣，無論何時(shí)何地你都將能夠通過無線網(wǎng)絡(luò)獲得大量的媒體信息和娛樂。

移動通信正在由單一的語音通信向多媒體方向發(fā)展,通過此途徑來加深我們對外界的感覺。

但不是這全部都將立刻發(fā)生。至今為止沒有一個(gè)人能夠完全掌握3G的發(fā)展的進(jìn)程。我們唯一確信的是2001年多媒體移動通信將沖擊日本市場，而且歐洲和北美也將很快發(fā)展多媒體通信市場。

3G在帶來高速的語音通路之外還集以IP為基礎(chǔ)的服務(wù)為一身,有強(qiáng)大的發(fā)展環(huán)境。向IP方向發(fā)展是至關(guān)重要的。IP技術(shù)是以簡單的數(shù)據(jù)包傳輸為基礎(chǔ)的, 可以使用戶同時(shí)上網(wǎng)，但是不必花錢除了我們發(fā)送或接收數(shù)據(jù)。IP 的自然無連接性可以大大提高存取速率: 文件下載只需要很短的時(shí)間，而且只需輕輕一點(diǎn)就能和網(wǎng)絡(luò)連接上。

3G采用多頻率通信技術(shù),并且達(dá)到 2 Mbit/s 的通路速度。與現(xiàn)在的移動網(wǎng)絡(luò)相比較,3G將會極大的提高網(wǎng)絡(luò)容量-因此將能夠支持更多的使用者, 同時(shí)能夠提供更多復(fù)雜的服務(wù)。3 GSynchronous CDMA(時(shí)分同步CDMA)，該標(biāo)準(zhǔn)是由中國大陸?yīng)氉灾贫ǖ?G標(biāo)準(zhǔn)，1999年6月29日，中國原郵電部電信科學(xué)技術(shù)研究院（大唐電信）向ITU提出，但技術(shù)發(fā)明始祖于西門子公司，TD-SCDMA具有輻射低的特點(diǎn)，被譽(yù)為綠色3G。該標(biāo)準(zhǔn)將智能無線、同步CDMA和軟件無線電等當(dāng)今國際領(lǐng)先技術(shù)融于其中，在頻譜利用率、對業(yè)務(wù)支持具有靈活性、頻率靈活性及成本等方面的獨(dú)特優(yōu)勢。另外，由于中國內(nèi)的龐大的市場，該標(biāo)準(zhǔn)受到各大主要電信設(shè)備廠商的重視，全球一半以上的設(shè)備廠商都宣布可以支持TD—SCDMA標(biāo)準(zhǔn)。該標(biāo)準(zhǔn)提出不經(jīng)過2.5代的中間環(huán)節(jié)，直接向3G過渡，非常適用于GSM系統(tǒng)向3G升級。軍用通信網(wǎng)也是TD-SCDMA的核心任務(wù)?！?WCDMA

寬帶碼分多址接入技術(shù)(WCDMA)提供的數(shù)據(jù)傳送速率遠(yuǎn)遠(yuǎn)大于現(xiàn)在我們采用的通信方式,提供高達(dá)2Mbit/s的傳輸速率, 大大提高了光纖對語音信號的傳輸率。3G提供更寬的帶寬是3G中存在的巨 大的潛能。例如，WCDMA能夠使語音信號、視頻信號和數(shù)據(jù)同時(shí)進(jìn)行傳輸。

WCDMA完全遵照了IMT-2000提出的2GHz帶寬標(biāo)準(zhǔn)(IMT-2000中心帶寬),就像是在歐洲采用的UMTS(全球的移動傳輸系統(tǒng))和日本采用的ARIB(語音信號工業(yè)標(biāo)準(zhǔn)聯(lián)盟)。

愛立信在WCDMA的研發(fā)方面走在了前列。公司早在1988年就在日本為移動通信網(wǎng)絡(luò)開始了WCDMA的實(shí)驗(yàn)活動。愛立信已經(jīng)在全球建立了WCDMA的測試系統(tǒng)。在2000年，愛立信

宣布了他建立了WCDMA的基站。·EDGE 全球革命性的提高傳輸速率將是原來的GSM和TSMA運(yùn)營商利用現(xiàn)有的設(shè)備提供3G服務(wù)。通過制定新的通信附加標(biāo)準(zhǔn)來對無線通信和網(wǎng)絡(luò)中樞進(jìn)化標(biāo)準(zhǔn)化,同時(shí)改革所有的IP業(yè)務(wù)和多媒體網(wǎng)絡(luò)?！?cdma2000 cdma2000對于提高寬帶傳輸速率和遞送高質(zhì)量的語音服務(wù)無疑是3G標(biāo)準(zhǔn)最有效率的。cdma2000標(biāo)準(zhǔn)的發(fā)展將會使移動通信系統(tǒng)能夠提供2Mbit/sec的數(shù)據(jù)傳輸率甚至超過這個(gè)標(biāo)準(zhǔn)。cdma2000提供的帶寬向我們展示了3G的潛能。舉例來說，cdma2000允許同時(shí)的傳輸多組聲音圖像數(shù)據(jù)。

cdma2000完全融合了IMT-2000標(biāo)準(zhǔn)，并且滿足了3G的標(biāo)準(zhǔn)。cdma2000可以通過現(xiàn)有的CMDA和TDMA在800到1900 MHz的頻段上實(shí)現(xiàn),就像日本在2GHz的光譜中實(shí)現(xiàn)。

愛立信是cdma2000研發(fā)的先行者,它制定了對無線通信和網(wǎng)絡(luò)中樞進(jìn)行改革的新標(biāo)準(zhǔn),同時(shí)也提出了對IP和多媒體網(wǎng)絡(luò)進(jìn)行改革的意見。· 藍(lán)牙

藍(lán)牙是在不同的裝置之間進(jìn)行雙通道短波傳輸?shù)墓_標(biāo)準(zhǔn)。舉例來說,它的出現(xiàn)標(biāo)志著通過電纜進(jìn)行移動通信連接掌上電腦或筆記本電腦的時(shí)代已經(jīng)過去。此外，藍(lán)牙能夠說數(shù)據(jù)傳輸同步化。存儲在智能數(shù)字助理上的日程表可以在個(gè)人計(jì)算機(jī)中藍(lán)牙能夠達(dá)到范圍里面自動更新。藍(lán)牙將成為通信領(lǐng)域中用于不同設(shè)備之間傳輸數(shù)據(jù)最重要的手段，同時(shí)它也將成為發(fā)展最快的發(fā)展領(lǐng)域。

藍(lán)牙技術(shù)是終端和其他設(shè)備使用移動通信網(wǎng)絡(luò)的關(guān)鍵。藍(lán)牙即可應(yīng)用到現(xiàn)在的2G網(wǎng)絡(luò)也可以支持3G系統(tǒng),它將會在未來的移動通信中占據(jù)越來越重要的地位。愛立信已經(jīng)研制出了藍(lán)牙裝置,包括T36藍(lán)牙手機(jī)和藍(lán)牙掌上設(shè)備。

藍(lán)牙是由愛立信公司首先研制的,但現(xiàn)在藍(lán)牙主要是由一個(gè)特殊的世界組織來主管。此技術(shù)已在所有電信器械生產(chǎn)商、計(jì)算機(jī)制造商以及芯片制造商中普及?！?Symbian Symbian是一個(gè)被包括愛立信，諾基亞，摩托羅拉和 Psion公司共同投資的項(xiàng)目。Symbian的目標(biāo)是通過以下兩種方式提高其在移動通信市場的份額: · 第一, 通過發(fā)展軟件的核心，優(yōu)化系統(tǒng)結(jié)構(gòu)，進(jìn)一步的研發(fā)手機(jī)通信設(shè)備工具(例如個(gè)人數(shù)傳助手，小巧的手機(jī)和通信器材)。

· 第二,制定移動設(shè)備傳輸信息的標(biāo)準(zhǔn)。Symbian的EPOC操作系統(tǒng)已經(jīng)研制成功，而且愛立信已經(jīng)在R380中使用了EPOC操作系統(tǒng)。· 無線傳輸通訊協(xié)定

無線傳輸通訊協(xié)定(無線傳輸通訊協(xié)定)是一個(gè)全球性的協(xié)議，是通過移動設(shè)備訪問英特網(wǎng)的公開標(biāo)準(zhǔn)。它可以使用戶通過移動設(shè)備例如手機(jī)和便攜設(shè)備訪問整個(gè)移動網(wǎng)絡(luò)和受據(jù)庫服務(wù)商,不用用不同的設(shè)備完成這些任務(wù)。

無線傳輸通訊協(xié)定允許統(tǒng)過建立“無線傳輸通訊協(xié)定微型瀏覽器”組織電話信息的方向, 同樣地網(wǎng)絡(luò)瀏覽器經(jīng)由英特網(wǎng)-個(gè)人計(jì)算機(jī)提供在線服務(wù)。典型地，無線傳輸通訊協(xié)定監(jiān)控屏將會顯示各種不同的服務(wù)或數(shù)據(jù)入口的若干超鏈接。

和采用無線傳輸通訊協(xié)定的手機(jī)一樣,愛立信也已經(jīng)宣布研制出一種無線傳輸通訊協(xié)定來服務(wù)開發(fā)者的裝備(WapIDE)和無線傳輸通訊協(xié)定出入口/代理,用移動的網(wǎng)絡(luò)在英特網(wǎng)和局域網(wǎng)絡(luò)環(huán)境中來橋接無線傳輸通訊協(xié)定申請和服務(wù)。除此之外，愛立信提供應(yīng)用專利, 像是愛立信本土化了英特網(wǎng)(ELI)給本地服務(wù) , 提供時(shí)間和發(fā)展環(huán)境給無線傳輸通訊協(xié)定申請的無線傳輸通訊協(xié)定應(yīng)用服務(wù)商。

愛立信是無線傳輸通訊協(xié)定論壇的四個(gè)最初成員之一。自從 1997 以后，當(dāng)它成立的時(shí)候, 無線傳輸通訊協(xié)定論壇已經(jīng)得到廣泛的工業(yè)廠商的支持，他們大部分都是是世界無線傳輸通訊協(xié)定論壇的成員。最新版的無線傳輸通訊協(xié)定標(biāo)準(zhǔn)，無線傳輸通訊協(xié)定 1.2.1,剛剛被開發(fā)出來。

我們將盡全力來推進(jìn)無線傳輸通訊協(xié)定，準(zhǔn)備協(xié)助運(yùn)營商和服務(wù)提供商在競爭中處與更有利的地位。這有助于我們調(diào)整現(xiàn)今的業(yè)務(wù)來適應(yīng)新經(jīng)濟(jì)的發(fā)展，更有效的利用資源，用創(chuàng)新的方法與客戶溝通。

3G能給我們帶來什么

3G時(shí)代人們將會享受到他為我們提供的哪些服務(wù)呢，形象的說，3G就是飛機(jī)上的視頻會議；3G就是病人接受及時(shí)救助的醫(yī)學(xué)專家；3G就是籃球迷不會錯(cuò)過的NBA比賽；3G就是與朋友共享你在夏威夷的美好假期?！?視頻手機(jī)因3G勃興而揚(yáng)帆啟航

一直以來，我們通過QQ、MSN等視頻聊天功能，與親朋好友進(jìn)行遠(yuǎn)程視頻聊天。由于手機(jī)數(shù)據(jù)傳輸速率、圖像處理傳輸、接受顯示設(shè)備等達(dá)不到要求使得手機(jī)視頻聊天擱淺。3G時(shí)代依靠3G網(wǎng)絡(luò)的數(shù)據(jù)高速傳輸，從而3G手機(jī)用戶可以“面對面”交談。通過手機(jī)視頻，相距萬水千山的母子能夠通過手機(jī)相聚，分別日久的戀人能夠通過手機(jī)重逢?！?３Ｇ推動手機(jī)購物進(jìn)入井噴期

用手機(jī)上網(wǎng)購物是一種新的購物方式，手機(jī)購物不僅讓消費(fèi)者足不出戶就能買到滿意商品 更使得消費(fèi)者能夠方便快捷的對商品進(jìn)行挑選比較，隨著我國3G網(wǎng)絡(luò)的不斷完善，越來越多的用戶將會選擇手機(jī)購物模式。我國的手機(jī)購物將會迎來一個(gè)高速增長期。

網(wǎng)上商家不僅將服裝、圖書、手機(jī)、玩具、音像制品等日常商品擺上網(wǎng)絡(luò)貨架，汽車、筆記本電腦、珠寶等高檔商品也在備選之列。人們只要拿出３Ｇ手機(jī)登陸購物網(wǎng)站查詢商品信息，就能夠買到心儀的物品。網(wǎng)上購物價(jià)格不僅比商場便宜，更能夠送貨到家，如果不滿意可以按期退貨，網(wǎng)上商家誠信承諾保證了消費(fèi)者的購物安全。· 寬帶上網(wǎng)使手機(jī)成為“小電腦”

雖然中國的3G之路剛剛開始，寬帶上網(wǎng)已是亮點(diǎn)業(yè)務(wù)，我們能在手機(jī)上收發(fā)語音郵件、寫博客、聊天、搜索、下載等，還有拔尖業(yè)務(wù)，如網(wǎng)絡(luò)游戲、手機(jī)導(dǎo)航、網(wǎng)上聊天等。· 手機(jī)辦公—OA系統(tǒng)桎梏開啟的鑰匙

傳統(tǒng)自動化辦公系統(tǒng)雖然較之從前大大提高了辦公效率，然而區(qū)域的局限使的 OA系統(tǒng)僅限于應(yīng)用局域網(wǎng)，這給企事業(yè)單位辦公帶來了很多的不方便。手機(jī)辦公可以隨時(shí)隨地與單位的信息系統(tǒng)保持聯(lián)系，完成辦公功能越來越受到人們的青睞。３Ｇ手機(jī)可以下載安裝office、java等辦公軟件，將傳統(tǒng)辦公軟硬件“壓縮”在手掌大的手機(jī)上?！?手機(jī)電視將液晶電視收入囊中

手機(jī)電視是利用具有操作系統(tǒng)和流媒體視頻功能的智能手機(jī)觀看電視的業(yè)務(wù)，它是利用CMMB技術(shù)推出的便攜式的移動的多媒體，不管是 GPRS手機(jī)還是CD－

MA1X手機(jī)，都需要在裝有操作系統(tǒng)的手機(jī)終端上安裝相應(yīng)的播放軟件，而相應(yīng)的電視節(jié)目則由移動通信公司或者通過相應(yīng)的SP來組織和提供。盡管３Ｇ發(fā)展一片欣欣向榮的景象，然而由于手機(jī)流媒體軟件，視頻影像的流暢、畫面質(zhì)量等技術(shù)方面存有問題，手機(jī)電視大踏步前進(jìn)還需要時(shí)日。

食品安全問題On the Food Security

Over the past couple of years, several cases of the food scandal have been disclosed on various media.The problem of food security has become a hot button across society.The prevalence of food insecurity has greatly impacted public health, which the government could not afford to ignore, according to the online edition of the People Daily.There are a couple of driving forces, I would argue, behind this undesirable tide.First, in the course of the rapid economic evolution, we ignore moral education, giving rise to the rising rate of the problem.More importantly, the lack of adequate regulation and punishment on those illegal producers enforces the trend.As Confucius instructed, it is better late than never.Prompt and strict measures should be taken to turn back this evil trend.The government should launch a massive moral campaign to educate all citizens and draw up tougher laws to crack down on those irresponsible corporations and prohibit them from entering the food industry again.I am firmly convinced that through our combined efforts we are bound to enjoy more risk-free foods in the days ahead.1、越來越： be increasingly + adj;be on the rise,the growing number of, sth is gaining great popularity.（強(qiáng)化版）
