阿基米德原理最初指的是浸在液体中的物体所受浮力的大小与液体的密度、物体排开液体体积的定量关系。对于浸在空气中的物体所受浮力的大小,初中物理教科书只说阿基米德原理也适用于气体,但未进行实验验证。本文通过实验,测得浸在空气中的物体所受浮力的大小,来验证阿基米德原理是否也适用于气体。 The Archimedes principle initially refers to the quantitative relationship between the magnitude of buoyancy and the density of the liquid and the liquid volume of the liquid that the object is immersed in. For objects immersed in air, the magnitude of the buoyancy, junior high school physics textbook only said that the principle of Archimedes also applies to gases, but no experimental verification. In this paper, the size of the buoyancy of an object immersed in the air is measured experimentally to verify whether the Archimedes principle also applies to the gas.
