摘要
本文根据数字化信息实验系统(简称DIS)的构成和实现功能,利用光电传感器和位移传感器同时测量单摆的周期和摆长,寻找单摆周期与摆长的定量关系。试验中使学生在熟悉DIS软件操作技能的基础上,能从中体验用计算机辅助系统进行科学探究的过程,学会科学探究的基本思想和基本方法,从而培养学生对科学研究的浓厚兴趣。
In this paper,the quantitative relationship between pendulum length and periodicity is studied through measurring the period and length of pendulum at the same time by Photoelectric sensors and displacement sensors. In this test, on the basis of studying the DIS software operation, students can experience the process of scientific research with computer-aided system,and understand the basic ideas and basic methods of scientific research. So students keep keen interest in scientific research.
