㈠ 手機發明英文翻譯
the invention of phone
㈡ 誰發明了手機(英文)
1973年4月的一天，一名男子站在紐約街頭，掏出一個約有兩塊磚頭大的無線電話，並打了一通，引得過路人紛紛駐足側目。這個人就是手機的發明者馬丁·庫帕。當時，庫帕是美國著名的摩托羅拉公司的工程技術人員。 這世界上第一通行動電話是打給他在貝爾實驗室工作的一位對手，對方當時也在研製行動電話，但尚未成功。庫帕後來回憶道：「我打電話給他說：『喬，我現在正在用一部攜帶型蜂窩電話跟你通話。』我聽到聽筒那頭的『咬牙切齒』——雖然他已經保持了相當的禮貌。」 到今年4月，手機已經誕生整整30周年了。這個當年科技人員之間的競爭產物現在已經遍地開花，給我們的現代生活帶來了極大的便利。 馬丁·庫帕今年已經74歲了，他在摩托羅拉工作了29年後，在矽谷創辦了自己的通訊技術研究公司。目前，他是這個公司的董事長兼首席執行官。馬丁·庫帕當時的想法，就是想讓媒體知道無線通訊——特別是小小的移動通訊手機——是非常有價值的。另外，他還希望能激起美國聯邦通訊委員會的興趣，在摩托羅拉同AT&T（AT&T也是美國的一家通信大公司）的競爭中，能支持前者。 其實，再往前追溯，我們會發現，手機這個概念，早在40年代就出現了。當時，是美國最大的通訊公司貝爾實驗室開始試制的。1946年，貝爾實驗室造出了第一部所謂的移動通訊電話。但是，由於體積太大，研究人員只能把它放在實驗室的架子上，慢慢人們就淡忘了。 一直到了60年代末期，AT&T和摩托羅拉這兩個公司才開始對這種技術感興趣起來。當時，AT&T出租一種體積很大的移動無線電話，客戶可以把這種電話安在大卡車上。AT&T的設想是，將來能研製一種行動電話，功率是10瓦，就利用卡車上的無線電設備來加以溝通。庫帕認為，這種電話太大太重，根本無法移動讓人帶著走。於是，摩托羅拉就向美國聯邦通訊委員會提出申請，要求規定移動通訊設備的功率，只應該是一瓦，最大也不能超過三瓦。事實上，今天大多數手機的無線電功率，最大隻有500毫瓦。 從1973年手機注冊專利，一直到1985年，才誕生出第一台現代意義上的、真正可以移動的電話。它是將電源和天線放置在一個盒子中，重量達3公斤，非常重而且不方便，使用者要像背包那樣背著它行走，所以就被叫做「肩背電話」。 與現在形狀接近的手機，誕生於1987年。與「肩背電話」相比，它顯得輕巧得多，而且容易攜帶。盡管如此，其重量仍有大約750克，與今天僅重60克的手機相比，像一塊大磚頭。 從那以後，手機的發展越來越迅速。1991年時，手機的重量為250克左右；1996年秋，出現了體積為100立方厘米、重量100克的手機。此後又進一步小型化、輕型化，到1999年就輕到了60克以下。也就是說，一部手機比一枚雞蛋重不了多少了。 除了質量和體積越來越小外，現代的手機已經越來越像一把多功能的瑞士軍刀了。除了最基本的通話功能，新型的手機還可以用來收發郵件和短消息，可以上網、玩游戲、拍照，甚至可以看電影！這是最初的手機發明者所始料不及的。 在通訊技術方面，現代手機也有著明顯的進步。當庫帕打世界第一通行動電話時，他可以使用任意的電磁頻段。事實上，第一代模擬手機就是靠頻率的不同來區別不同用戶的不同手機。第二代手機——GSM系統則是靠極其微小的時差來區分用戶。到了今天，頻率資源已明顯不足，手機用戶也呈幾何級數迅速增長。於是，更新的、靠編碼的不同來區別不同的機的CDMA技術應運而生。應用這種技術的手機不但通話質量和保密性更好，還能減少輻射，可稱得上是「綠色手機」。

㈧ 關於手機發明和用途的英語作文
Before the devices that are now referred to as mobile phones existed, there were some precursors. The development of mobile telephony began in 1918 with tests of wireless telephony on military trains between Berlin - Zossen. In 1924 public trials started with telephone connection on trains between Berlin - Hamburg. In 1925 Zugtelephonie A. G. is founded to supply train telephony equipment[8] and in 1926 telephone service in trains of the Deutsche Reichsbahn and imperial post on the route between Hamburg and Berlin is approved and used.[8] This phone service was only offered to 1st class travelers, but in 1918, some 5 years after the invention of Meißnerischen tube based transmitters, the German Reichsbahn in Berlin led experiments with telephony via radio.
The first mobile telephone calls were made from automobiles in 1946. The Bell System's - Mobile Telephone Service - inaugural call was made on 17 June of that year in St. Louis, Missouri, followed by Illinois Bell Telephone Company's car radiotelephone service in Chicago on 2 October. The MTS phones were composed of vacuum tubes and relays, and weighed over 80 pounds (36 kg). There were initially only 3 channels for all the users in the metropolitan area, increasing later to 32 channels across 3 bands. This service continued into the 1980s in large portions of North America. Due to the small number of radio frequencies available, the service quickly reached capacity. In 1956, the world』s first partly automatic car phone system, Mobile System A (MTA), was introced in Sweden.
Mobile phones are used for a variety of purposes, including keeping in touch with family members, concting business, and having access to a telephone in the event of an emergency. Some people carry more than one cell phone for different purposes, such as for business and personal use. Multiple SIM cards may also be used to take advantage of the benefits of different calling plans— particular plan might provide cheaper local calls, long-distance calls, international calls, or roaming. The mobile phone has also been used in a variety of diverse contexts in society. Today you can hardly find someone without a mobile phone.
