模拟“科研”工作中的一般思路和方法进行教学,能够调动学生的思维活动,提高课堂的听课效果,并能诱发学生设想,创意和探索的精神,为改革,创新埋下种子。为此我在《电子技术》讲课中,尝试了这种方法,其中“稳压电源”部分内容的授课就是一例。直流稳压电源的输入端是接入单相交流电网的,输出端带动负载工作。电网允许有土10％波动,而负载也是变化的,这些因素都会使直流电源的输出电压发生变化,“稳定电 To simulate the general ideas and methods in “scientific research” work can mobilize students ’thinking activities and improve classroom lectures. It can also arouse the students’ imagination, creativity and exploration spirit and plant seeds for reform and innovation. For this reason, I tried this method in the lecture of “Electronic Technology”, of which the teaching of “regulated power supply” is an example. DC power supply input is connected to single-phase AC power grid, the output driven load. Power grid allows 10% fluctuations in soil, and the load is also changing, these factors will make the DC power supply output voltage changes, "stable electricity
