摘要
本文用数字电路技术演示物理实验中的交流电、整流和滤波,使演示更加直观简单。用计算机和电子技术充实物理实验是当前物理教具改革的主流。
This article says that it is easier and directly perceived through the senses to show A. C. commutation and filtercircuit with digital electric circuit technology in physical teaching.It's the main current in the present reform of physical teaching to use the computer and electric technology tocnrich physical experiments.
