用于实验的仪器,底部由一个三角形的重铁架组成,这样的构造可以使得整个仪器重心较低,使其更稳,不易倒.中间接连一根刚型支柱,链接顶部的圆盘,圆盘内有凹槽,可以放置物品,这样的设计可以使物品不容易在旋转中转出盘面.实际上,我们的道具还有塑料大圆盘,用以完成我们接下来的整个实验. The instrument used for the experiment is composed of a triangular heavy iron frame at the bottom, which can make the center of gravity of the instrument lower and make it more stable and less prone to fall in. In the middle, there is a rigid type pillar which links the top disc, circle There are notches in the tray for items to be placed so the items do not easily come out of the tray during rotation. In fact, our props also have large plastic discs to complete our entire experiment.
