前言

據(jù)統(tǒng)計，全球有超過40%的人在學(xué)習和使用英語；超過85%的科技資料（如書籍、期刊、

專利說明書和內(nèi)部技術(shù)報告等）運用英語語言；不論在哪個國家召開國際學(xué)術(shù)會議，所規(guī)定使

用的工作語言一般也都是英語。因此，英語既是人們交流的主要工具，也是開展科學(xué)研究的重

要工具。

伴隨“一帶一路”的建設(shè)和中國高鐵“走出去”戰(zhàn)略的實施，海外高鐵項目建設(shè)、裝備制

造等國際交流合作愈發(fā)緊密，這就要求機械工程類專業(yè)學(xué)生既要精通技術(shù)知識，又要熟練應(yīng)用

專業(yè)英語，要成為具備國際技術(shù)交流能力的復(fù)合型人才。

目前，各高校紛紛開設(shè)專業(yè)英語課程。本書的編寫是為滿足機械工程專業(yè)英語課程教學(xué)需

要和涉外人員的自學(xué)參考要求。內(nèi)容結(jié)合高鐵等交通應(yīng)用背景，以現(xiàn)代機械工程為主線，借助

英語工具開展機械工程在交通領(lǐng)域的應(yīng)用實踐，而不是通過專業(yè)實踐去鞏固英語知識，最終要

提升讀者運用英語進行交通背景下機械工程專業(yè)活動的整體水平，能夠進行國際交流研討、專

業(yè)英語文本寫作、了解國際科技創(chuàng)新、在國外順暢進行施工交流等實踐，使其將專業(yè)能力、英

語能力與應(yīng)用能力三者有機融合。

本書共分7章，包括機械工程簡介、機械工程相關(guān)的熱點話題、機械制造、機械設(shè)計及理

論、機械電子工程、車輛工程、材料科學(xué)與技術(shù)等相關(guān)知識點。內(nèi)容較常規(guī)的機械工程專業(yè)英

語書都有重大突破，交通特色鮮明。首先，內(nèi)容新穎、與時俱進，介紹工業(yè)4.0、高鐵、機器

學(xué)習等熱點前沿技術(shù)；其次，覆蓋面廣、體系完整，涵蓋機械工程一級學(xué)科下所有的二級研究

方向，尤其是車輛工程為獨立一章；第三，學(xué)科知識與交通背景結(jié)合，例如，介紹鋼軌打磨、

鋼軌在線監(jiān)測、軌道交通材料、復(fù)合材料等內(nèi)容。另外，編寫形式有較大創(chuàng)新，充分利用現(xiàn)代

數(shù)字技術(shù)，打造立體化新形態(tài)圖書，正文相關(guān)知識配二維碼，添加用英文講解的機械工程視頻、

前沿技術(shù)英文微課等拓展素材。

本書由北京交通大學(xué)的相關(guān)專家和技術(shù)人員編寫。蘭惠清任主編，負責全書的構(gòu)思、組稿

和統(tǒng)稿。各章編寫分工如下：第1章和第2章由蘭惠清編寫，第3章由曹建國、房善想和

張勤儉編寫，第4章由張朝輝編寫，第5章由董立靜和陳光榮編寫，第6章由陳星宇編寫，

第7章由杜云慧編寫。全書由史紅梅主審，李聰協(xié)助完成統(tǒng)稿工作。

在本書的編寫過程中，編者參考了國內(nèi)外專家學(xué)者的最新研究成果和資料，在此向這些專

家學(xué)者表示誠摯的感謝。

機械工程所涉及的內(nèi)容廣泛，學(xué)科跨度大，新材料、新技術(shù)發(fā)展迅速，加之編者水平有限，

書中難免有不足之處，懇請廣大讀者提出寶貴意見。
