本书主要介绍电气工程及其自动化专业英语的阅读、理解与翻译。全书共分电工电子、电机及其控制、发电输电配电与电力系统、特殊电源与可再生能源发电、计算机与智能技术五大部分，每一部分又分别包含英语原文、专业英语词汇、课文注释、参考译文和专业英语翻译与写作知识五部分。     读者对象：本书取材新颖、内容丰富、注释详尽、译文准确，是电气工程及其自动化专业英语的适用教材，也可作为其他相近专业的参考书，还可供有关技术人员选用。

前言 由本人主编的《电气工程及其自动化专业英语》一书自出版以来，深受广大读者的欢迎和大力支持，该书的重印和再版量不断攀升。但是，该书毕竟出版时间较长，其中不少内容已显陈旧，因此有必要进行重新编著。 正是出于以上考虑，本人重新编著了《电气工程及其自动化专业英语》一书。在本书的编著过程中，我的在校研究生林卿生、杨华、王宝福、谢友慧、王凯、陈向杰、赵杰、刘海静、邓志辉和王少夫同学，在资料收集、文字录入、图表和曲线的绘制及扫描等方面做了大量工作，在此一并致谢。 本人虽然长期工作在专业英语的教学第一线，且对该门课程的教学内容和方法有一定体会，但毕竟水平有限，故书中谬误之处在所难免，敬请读者不吝指正。 戴文进于南昌大学 目录
