本書第1版自2010年8月出版以來,被多所高校的電氣工程及其自動化專業及其他電氣類專業作為教材用于專業英語的教學中。編者在教學過程中也收到了使用本書的教師們的反饋信息,他們在對本書給予充分肯定的同時,也提出了寶貴的建議和修改意見,在此表示由衷的感謝。
本書第2版在保持本書專業知識點突出、實用性強的基礎上,主要做了以下三方面的修訂和補充:1)補充了與電氣工程及其自動化專業發展相關的內容,如特種電機、微電網技術等方面的內容。
2)對部分章節的內容安排進行了調整,使整本書各知識點內容在突出專業特點和重點的同時,內容銜接更緊密。
3)為了便于相關專業和不同年級讀者的使用,本書每章后增加了對重點或難點句子的中文注釋,可幫助讀者理解和學習有關知識點內容。
本書第2版由北京石油化工學院、沈陽工業大學、太原理工大學、中原工學院幾所高校多年從事專業英語教學工作的老師聯合修訂。第2版共包括電氣工程基礎(第1~5章)、控制理論與技術(第6~10章)、電機與電器(第11~15章)及電力系統(第16~20章)4個部分,整體結構與本書第1版保持一致。參與本書修訂工作的有王偉、韓肖清、張殿海、馬景蘭和裴素萍5位老師。全書由王偉和馬景蘭老師統稿。張艷麗老師由于工作原因未參加本版的修訂工作,相關內容由沈陽工業大學張殿海老師負責修訂,在此也對張艷麗老師在本書第1版中所做的工作表示感謝。此外,北京石油化工學院的李偉、太原理工大學的王鵬敏和河南省建筑科學研究院的劉禹等也對本書的修訂做了許多工作,在此一并表示感謝。
由于編者水平和經驗有限,書中難免存在疏漏和不足之處,敬請讀者批評指正。
