摘　　要：论文研究线性电阻与非线性电感串联RL串联的一阶非线性电路的暂态过程。利用有限增量法求出RL非线性一阶电路暂态过程的理论解,同时通过实验测出RL非线性一阶电路充电过程的曲线,理论与实验充电曲线基本吻合。经比较,其充放电过程遵循完全不同的规律,并出现临界慢化现象。In this paper, we study the linear and nonlinear inductance in series resistance RL series of first order ？onlinear circuit transient process. Limited incremental method is used to derive nonlinear first-order RL circuit transient process of the theoretical solution, at the same time, through the experiment to measure RL curve of non-linear first-order circuit charging process, the charging curve fits in theory and experiment. Compared with RL first-order linear circuit, RL nonlinear first-order circuit charging and discharging process comply with the laws of completely different, and appear the phenomenon of critical slowing down.
