內(nèi)容簡介

　　《電子通信專業(yè)英語》共分兩部分：第一部分為電子、通信專業(yè)公共專業(yè)基礎(chǔ)課（電路分析、模擬電路、數(shù)字電路等）；第二部分為通信專業(yè)課（通信原理、通信系統(tǒng)、衛(wèi)星通信、光纖通信、數(shù)據(jù)通信等）。本教材各專業(yè)在安排教學(xué)時(shí)，可選擇15課左右的專業(yè)基礎(chǔ)課內(nèi)容，15課左右專業(yè)課內(nèi)容，剩余各課內(nèi)容可安排作為學(xué)生課外閱讀材料。本教材估計(jì)教學(xué)時(shí)數(shù)為50～60學(xué)時(shí)。文中對(duì)較為難懂的單詞、短語作出了中文釋義，對(duì)課文中較難的句子給出了參考譯文，并在文章后面配有一定量的練習(xí)題，便于讀者對(duì)文章內(nèi)容的理解和掌握。通過對(duì)本書的學(xué)習(xí)，可以使讀者掌握和擴(kuò)大專業(yè)英語詞匯量及術(shù)語，了解科技文獻(xiàn)的表達(dá)特點(diǎn)，提高閱讀和理解原始專業(yè)英語文獻(xiàn)的能力，掌握英語翻譯技巧。有助于提高讀者的閱讀能力和開闊讀者的視野。本書適合作為高職院校和成人高校以及自學(xué)考試等的電子通信類教材。
