摘要
通过设计"配重钢珠袋"改进了超重失重"液体压强计演示装置",在向上和向下两个运动过程中实现拉力的自动化改变,根据液体压强计的液面变化,演示物体的超重失重现象.
A counterweight steel balls were used in the manometer demonstration device for overweight and weightlessness. In the up and down movement, tension could change automatically. By using the liquid level change of the manometer, the phenoment of overweight and weightlessness were demonstrated.
