前言
據(jù)統(tǒng)計(jì),全球有超過40%的人在學(xué)習(xí)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(bào)告等)運(yùn)用英語語言;不論在哪個(gè)國家召開國際學(xué)術(shù)會(huì)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(shí)施,海外高鐵項(xiàng)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(jī)械工程類專業(yè)學(xué)生既要精通技術(shù)知識(shí),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(jī)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(jī)械工程為主線,借助
英語工具開展機(jī)械工程在交通領(lǐng)域的應(yīng)用實(shí)踐,而不是通過專業(yè)實(shí)踐去鞏固英語知識(shí),最終要
提升讀者運(yùn)用英語進(jìn)行交通背景下機(jī)械工程專業(yè)活動(dòng)的整體水平,能夠進(jìn)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(jìn)行施工交流等實(shí)踐,使其將專業(yè)能力、英
語能力與應(yīng)用能力三者有機(jī)融合。
本書共分7章,包括機(jī)械工程簡介、機(jī)械工程相關(guān)的熱點(diǎn)話題、機(jī)械制造、機(jī)械設(shè)計(jì)及理
論、機(jī)械電子工程、車輛工程、材料科學(xué)與技術(shù)等相關(guān)知識(shí)點(diǎn)。內(nèi)容較常規(guī)的機(jī)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(shí)俱進(jìn),介紹工業(yè)4.0、高鐵、機(jī)器
學(xué)習(xí)等熱點(diǎn)前沿技術(shù);其次,覆蓋面廣、體系完整,涵蓋機(jī)械工程一級(jí)學(xué)科下所有的二級(jí)研究
方向,尤其是車輛工程為獨(dú)立一章;第三,學(xué)科知識(shí)與交通背景結(jié)合,例如,介紹鋼軌打磨、
鋼軌在線監(jiān)測(cè)、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(shí)配二維碼,添加用英文講解的機(jī)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(fù)責(zé)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(jī)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(qǐng)廣大讀者提出寶貴意見。
