摘　　要：以功率因数的提高为例,将正弦稳态电路的理论教学与工业应用相结合.在实验教学中鼓励学生自己设计电路,进行实验对比分析,在实验结果出现问题时,结合功率因数在电力系统中的实际应用,让学生再次设计和分析电路并进行实验,使理论教学有效地结合,取得了满意的教学效果.Combined with quality education, the theoretical instruction and the practice for the industrial application of the improvement of power factor in the steady-state sine circuits have been mentioned. All sorts of methods for the improvement of power factor have been discussed in the theoretical instruction and the students who design the experimental circuits and analyze the results of the experiments by themselves will be encouraged. The experimental circuits combined with the practical application in the electric power system have been done again after mistakes have been found out in the experimental results. The instructional strategies of the steady-state sine circuits have been perfected and the instructional effect is satisfied to the teachers and the students.
