摘　　要：针对物理教材中浮力实验存在的问题,制作改进浮力实验装置。利用连通器原理使液体从容器底部注入,使液面平稳上升,从而完成测量对待测物块部分浸入、浸没和加大浸没深度的实验操作过程;同时采用颜色分明的待测物块,将弹簧测力计悬挂在支架上,能够保证稳定观察弹簧测力计示数的变化过程,从而使得实验效果更加明显。实验装置可同时探究浮力的大小与液体密度的关系、浮力的大小与物块密度、物块形状的关系。新的实验器材相比于教材中原有的实验装置可以有效地减小误差,增加了实验操作的方便性。Aiming at the problems of buoyancy experiment in physics textbooks, an improved buoyancy experiment device is made. The liquid was injected from the bottom of the container by using the principle of the connector, so that the liquid level rose steadily, so as to complete the experimental operation process of measuring partial immersion, immersion and increasing immersion depth of the object block to be measured. At the same time, the spring dynamometer is suspended on the bracket with a clear color block to be measured, which can ensure the stable observation of the change process of the spring dynamometer indication, so that the experimental effect is more obvious. The experimental device can simultaneously explore the relationship between buoyancy and liquid density, and the relationship between buoyancy and bulk density and bulk shape. Compared with the original experimental device in the textbook, the new experimental device can effectively reduce the error and increase the convenience of experimental operation.
