摘　　要：首先,从数学上统一了一阶电路各响应的电路模型,推导出三要素公式,阐明三要素的物理意义。其次,从不同角度对全响应进行分解,阐明一阶电路各响应之间的关系;最后,通过工程实例中的一阶RC电路和一阶GL电路,引导学生理解一阶电路的物理意义,认识一阶电路在工程中的应用,激发学生的学习兴趣,培养学生的工程思维。面向压缩学时背景与新工科建设需求,结合教学实践探讨了一阶电路时域分析内容的教学方法,对工科高校电路理论教学具有一定的参考意义。Firstly,the circuit model of first-order circuit is unified mathematically,and the formula of the three elements method is derived,and the physical meaning of the three elements is clarified.Secondly,the total response of first-order circuit is decomposed from different perspectives,and the relationship between the responses of the first-order circuit is clarified.Finally,through the first-order RC circuit and the first-order GL circuit in the engineering examples,the students are guided to understand the physical meaning of the first-order circuit,and the application of the first-order circuit in the engineering,and students'interest in learning is stimulated and their engineering thinking is cultivated.In this paper,in the case of compressed teaching time and the need of new engineering construction,the teaching method of time domain analysis of first-order circuit is discussed combined with teaching practice,and it has a certain reference significance for the teaching of circuit theory in engineering colleges.
