传统实验装置演示超重和失重现象时由于受到仪器原理等因素的制约,变化过程时间短,学生无法仔细观察与定量分析实验数据.而利用DIS数字化实验、传感器等实验设备,让学生自己动手探究了超重失重的过程,有利于学生直观、形象的认识超重和失重现象,理解超重和失重、完全失重现象的本质. Due to the constraints of instrument principle and other factors, the traditional experiment device demonstrates that the process of overweight and weightlessness is short and the students can not carefully observe and quantitatively analyze the experimental data.Be the use of DIS digital experiment, sensors and other experimental equipment, let the students do their own research Overweight and weightless process, is conducive to students intuitive, image recognition of overweight and weightlessness, understanding of the phenomenon of overweight and weightlessness, total weightlessness.
