【摘要】 美国“电路”课程教材《工程电路分析》一书是以工程类电工电子人才培养为目标，系统地阐述了线性电路的基本概念和分析方法；以时域分析为主线，递次引入直流、频域正弦交流（相量）、奈培频率和复频域分析，使学生能自然直观地深刻理解拉氏变换在电路理论中的应用，很具特色。更多还原

【Abstract】 This paper introduce and comment on the textbook 《Engineering circuit Analysis》 of USA. Its authors wroted for the students working at electrical and electronic enginering. By the main of time domain function,the the book intreduce the direct current,sinusoidal frequency domain (phasor),neper frequency domain (exponent) and complex frequency domain (damping exponent sinusoidal function), and derived the Laplace transform naturally. It made it easy and deep for students to understand the application of Laplace fransform in circuit theory.更多还原
