吴霞：女，汉族1964年9月生，籍贯浙江，中国计量大学，副教授；毕业于浙江大学，至今教学工作31年，长期致力于电路基础等课程的教学。
本书共分为 6章。第 1章为绪论，主要讲述电路实验入门基本知识。第 2章为常用元器件和电子仪器的使用，本部分先介绍了电路中常用的电子元器件，然后重点介绍了常用电子仪器的使用方法。第 3章为 Multisim 14电路仿真与设计实例，重点介绍了 Multisim 14的软件及仿真分析方法，并给出 4个电路仿真实验案例。第 4章为电路分析基础实验，给出了 14个电路实验及 5个电子技术实验。实验任务难度由浅到深，从基础实验入手，递进式地引入设计性实验，循序渐进地培养学生的实验能力，每个实验均配有预习自检环节。为了方便学生在“互联网 ”时代下的移动学习，部分实验配有微课视频，可扫描二维码进行观看学习。第 5章为第 4章实验 4.1～4.10的全文英文翻译。第 6章为综合实验项目研究与实践，可为学习基础好的学生提供课外综合电子技术实践选题，提高学生的创新能力。本书可以作为高等院校及独立学院电路实验课程的教材和教师的教学参考书，同时也可以作为非电类专业学生电路与电子技术实验教材和留学生学习电路实验的教程。
前 言
电路实验，是高等院校电子、电工类本科生学习专业技术基础的*门实践课，是基础课与专业课的搭桥课，是培养学生解决问题思维、专业思维和基本技能的重要课程。本书以培养和提升学生实践能力和创新能力为目标，对培养学生探究科学实验兴趣、训练学生工程实践的逻辑思维能力有很好的指导作用。本书以引导为目的，将学生带入自主学习的实验领域中，重点培养学生电路基础及设计性实验、综合性实验能力，昀终帮助学生完成电路实验。本书难度适中，强调基础性实验与设计性实验相结合，注重理论联系实际，培养学生独立解决问题的能力。本书在设计上沿用了传统必要的基础验证性实验原理。在难度的设计上由浅入深，主讲教师可根据学生所学专业、差异性学习特点、课程的学时数选择实验项目和安排相应的实验任务。本书将现代的 EDA技术融入实验项目中，通过典型的仿真实例介绍，让学生掌握电路仿真工具的使用技巧，告诉学生该如何通过电路仿真设计完成实验，采取循序渐进的方式设定若干阶段，逐步放手，让学生领会学习进阶的乐趣，培养学生利用计算机仿真软件进行电路分析的能力。本书主要特点如下所述：*，在教学理念上，以学生为中心，关注每位学生完成实验项目的学习目标达成进度，递进式培养学生的实践能力。在实验设计上保留传统必做的经典验证性实验，设计了具有扩展性的设计性实验及提高学生更高层次能力的综合性实验，为学有余力的学生留出发展能力的学习空间。第二，在教学方法上，增加了学生实验预习及课前检测环节。强调学生实验预习环节的重要性，以问题为导入，帮助学生抓住实验课预习的重点，养成自主学习的习惯。改变以往学生在实验教学中让教师“抱着走”的惰性，培养学生批判性的思维能力。第三，本书第 5章为电路基础实验英文翻译，方便留学生进行电路实验学习，同时也为工科学生学习专业英语打下良好的基础。第四，本书具有新形态教材特征。书中多个实验项目的基础实验配有帮助学生课前预习的微课视频，学生可随时随地，通过扫描二维码方式，碎片化地进行课前学习。本书分为 6章。全书由吴霞主编，并负责总体规划和全书统稿。书中所有微课视频，由李弘洋完成二维码生成编辑工作。其中，第 1章为绪论，第 2章为常用元器件和电子仪器的使用，第 3章为 Multisim14电路仿真与设计实例，第 4章为电路分析基础实验，第 5章为电路基础实验英文翻译，第 6章为综合实验项目研究与实践。
本书由吴霞编写第 1章，第 4章第 4.1节、4.9节，第 5章第 5.1～5.2节，第 6章第 6.3节；沈小丽编写第 2章第 2.1～2.5节，第 4章第 4.12节；李弘洋编写第 2章第 2.6～2.9节，第 3章第 3.1～3.4节；王燕杰编写第 3章第 3.5节、3.7节，第 4章第 4.11节，第 4.15～4.18节，第 5章第 5.3～5.10节，第 6章第 6.4～6.14节；李敏编写第 3章第 3.8节，第 4章第 4.2～4.6节，第 4.10节，第 4.13～4.14节，第 6章第 6.1～6.2节；池金谷编写第 3章第 3.6节、3.9节，第 4章第 4.7～4.8节，第 4.19节，第 6章第 6.15～6.16节。本书编撰人员，皆为电路实践教学工作的一线教师，结合近 30年的教学改革体会，编写了与学生水平相适应的电路实验教材，满足不同层次学生需求。本书同时也可作为电路电子实验用书，面向对象为普通高校工科类应用型本科生及留学生。由于编者水平有限，书中难免存在疏漏和不足之处，恳请广大读者提出宝贵意见。编 者 2017年 7月
