做浮力原理的实验很多,但是能形象、直观、简单地说明问题的却很少。针对这种情况,我设计了一种利用浮力原理能在水面上直接做的实验,形象直观地说明了问题。一、结构与组装1.结构。如图1所示,此装置由以下构件组成:(1)浸水量筒;(2)标尺;(3)压缩弹簧;(4)下隔板;(5)细线;(6)T型架板;(7)支架;(8)上隔板;(9)手柄;(10)盛水量筒;(11)滑轮。
There are many experiments on the principle of buoyancy, but there are few examples that can visually and intuitively describe the problem. In view of this situation, I designed an experiment that could be done directly on the surface of the water using the buoyancy principle, and illustrated the problem visually and intuitively. First, structure and assembly 1. Structure. As shown in Fig. 1, this device is composed of the following components: (1) water-immersed measuring cylinder; (2) scale; (3) compression spring; (4) lower partition; (5) thin line; (6) T-frame (7) bracket; (8) upper partition; (9) handle; (10) water holding cylinder; (11) pulley.
