利用陶瓷片代替铅柱进行分子引力的实验,借助DIS系统中的力学传感器,检验实验改进后的效果,发现操作简单,实验效果显著,教学效度高.
The experiment of molecular gravitation was carried out by using ceramic chip instead of lead column. With the help of the mechanical sensor in DIS system, the improved experimental results were tested. The results showed that the experiment was simple, the experimental effect was remarkable and the teaching efficiency was high.
