双语教学是随着我国高等教育改革的不断深入而产生的，并且呈现出课程门数不断增加的发展趋势。双语教学既可以在教授科技知识的同时帮助学生稳步提升外语应用能力，还可以吸取国外一些好的教学方法，因此，近年来得到了较快的发展。
对于过程装备与控制工程专业的本科教学，由于国外高等工科院校没有对应的专业，因而相应的原版英文教材很少，给双语教学带来了较大的困难，所以我们编写了本书。本书为云南省普通高等学校“十二五”规划教材，同时也是昆明理工大学省级一流本科专业过程装备与控制工程专业建设的成果之一。本书着重介绍过程装备研究或设计中所涉及力学方面的基本理论和基本知识，目的是使学生在提高英语应用能力的同时为随后的专业课程学习奠定基础，在过程装备与控制工程专业人才培养过程中起着较为重要的作用。本书在编写过程中注重理论与方法的有机结合，并注意吸取国外教材一些好的编写方法，力求通俗易懂、简明实用。
本书由朱孝钦主持编写。陈涛编写第1章、第2章和第3章；朱孝钦编写第4章、第7章和第8章；王修武编写第5章；孙雪剑编写第6章。全书由朱孝钦统稿。本书得到美国休斯敦大学Fan Wang 教授的审阅和指导。
本书得到云南省教育厅的资助，也感谢昆明理工大学教务处、化学工程学院的大力支持。
我们希望本书能对过程装备与控制工程专业的双语教学起到一定的推动作用，也希望关注、使用本书的教师和同学提出宝贵的意见。
由于编者水平有限，书中难免有些疏漏，敬请读者批评指正。
