摘　　要：基于玻意耳定律和阿基米德原理,设计了全机械密度仪,对铝铁铜样品进行了测量,测量结果与标准值相近.本密度仪成本低,可用于固体或液体的无污染测量.A full-mechanical densimeter was designed based on Boyle law and Archimedes principle.The densities of Al,Fe and Cu samples were measured by this full-mechanical densimeter,and the results were similar to the standard value.The densimeter was low-cost and could be used to nonpollution measurement of the density of solids and liquids.

关 键 词：密度 玻意耳定律 阿基米德原理
