摘　　要："电路理论"和"电工学"课程的实验教学一般包含日光灯电路功率因数提高实验。现有的实验操作方法存在缺陷。直接将电容器通过开关投到220V电源上,这种操作会导致设备损坏和对学生产生误导。本文分析了上述缺陷的原因,并对此提出了改进方法。Power factor increasing experiment for fluorescent lamp circuit is included in curriculums of Electric Circuit Theory and Electrotechnics. There is defect in the current experimental operation method. The operation of switching the capacitor to 220 V voltage source directly can lead to damage equipments and mislead students. This paper analyzes the causes of the defects,and put forward the improvement method.
