摘　　要：通过实验测量结果及理论计算2组曲线的比较,研究了LR串联电路的稳态特性.发现理论值与实际值之间存在非正常误差范围的结果.本文通过多组(R取不同值)实验结果来分析电感元件中存在内阻时所带来的影响,探讨做好本实验的规律.By comparing the experimental and theoretical diagrams, the steady-state characteristic of LR circuit is investigated. The difference between the theoretical value and the experiment results exceeds the measurement error. Several experiment results （with R takes different values） are used to analyze the the influence of the internal resistance of the inductance. Some useful guidelines for successfully carrying out the experiment are presented.
