前 言
随着科学技术的进步，液压与气压传动技术得到飞速发展，被广泛应用于机械制造、
航空、航天、冶金、交通运输、建筑工程、水利、化工、纺织、生物制药、能源技术等领
域中。为了培养学生实际应用液压与气压传动技术的能力，满足实际工作岗位需求，编者
在总结多年教学实践经验的基础上编写了本书。
本书以职业教育倡导的能力和目标为主线，以就业为导向，采用任务引领、启发训练
等方法优化教学内容，能充分调动学生学习的主动性和创造性。本书不拘泥于理论研究，
注重培养学生对液压与气压传动技术的理解及实际应用。
本书具有以下特点：
（1）选取与液压与气压传动相关的典型案例作为教学项目来承载教学内容，采用任务
导向、任务驱动模式，对各类元件的工作原理、结构和应用等知识进行了深入浅出的介绍。
（2）融入了课程思政元素，以技能报国的爱国主义精神、爱岗敬业的劳动精神和精益
求精的工匠品质为思政主线，培养学生“依规范、重安全、保质量”的综合职业素养。
（3）围绕重要的技能点及知识点安排仿真设计训练任务，强化学生的思维能力及团队
协作意识。
（4）融入大量微课视频，可扫描书中二维码浏览，便于学生预习和复习，充分体现“互
联网+”新形态一体化教材理念。
（5）践行校企双元育人，邀请聊城中通客车股份有限公司苏金钟工程师参与本书编写，
选用部分企业真实案例作为支撑，推动校企双元育人发展。
（6）与时俱进，将党的二十大精神融入教材，用习近平新时代中国特色社会主义思想
武装学生头脑。
本书可作为高职高专院校机电一体化、电气自动化、机械制造及自动化等专业学生的教材，也可作为
相关专业工程技术人员的参考用书。
本书提供了丰富的教学资源，包括微视频、教学课件和习题答案等，需要者可以通过
