封底
本书可作为高等院校电类专业“电路分析”双语课的教材,以更清晰、生动、易于理解的方式来阐述电路分析的方法。全书分为两部分,第一部分包括第1~10章,主要介绍直流电路;第二部分包括第11~19章,主要介绍交流电路。本书可以作为大学两学期或三学期的教材,授课教师也可选择适当的章节,将其用作一学期课程的教材。
本书特色
每章均由相关历史人物或者工程师职业要求开篇,然后通过引言部分将本章内容与前面章节的内容衔接起来,同时提出本章学习的目标。每章结束部分总结了本章要点及相关公式。
简捷清晰、循序渐进地介绍所有原理,尽可能避免影响对概念和整体内容理解的细节的过多赘述。
每节都给出大量切实可行的例题,并进行了详细解答。部分例题还给出了两到三种求解方式,以帮助同学理解和比较不同的解题方法,加深对所学内容的理解。
每章最后一节着重于本章概念的实际应用,至少包括一个实际问题或者实际器件,以帮助学生了解所学概念是如何应用于实际问题的。
按照ABET对集成计算机工具的要求,鼓励学生使用PSPICE和Multisim等计算机辅助分析软件。
