基于弦线振动实现固液体密度的计算与测量

摘要

This paper connected chord vibration with static measurement and made use of a new method to study consistency of solid and liquid. There are simple theory and reliable method, and comprehend more deeply for chord vibration and static measure merit. From the result , the error is very tiny when compared with standard consistency. And it shows a practical method and has application value.%将弦线振动的研究与静力称衡法相结合,得出测量固体和液体密度的一种新方法.该实验原理简单、方法可靠,从测量结果可知,所测固体和液体的密度与标准值相比,其误差较小,说明实验方案确实可行,具有一定的应用价值.
