摘要
通过理论推导和实验结果分析得出,在固体密度测量时,只有当被测固体的体积为3~5cm3且被测固体与测量所用液体密度相差不超过一个数量级时,空气浮力对固体密度测量的影响才可忽略不计.
y inference and analysis of the experiment, we can have the result. When we do solid density survey, and when surveyed solid volume is 3~5cm3, the influence of air buoyancy toward solid density survey is countless. There is no more than one quantitative limit between surveyed solid density value and liquid density value.
