摘要
利用电动音叉仪测量液体密度,分析原实验仪器存在的不足,对原实验装置做了改进.通过测量水的密度,结果显示改进后的实验仪器不但提高了测量的精确度,而且操作更快捷、方便.
It was analyzed the problems existing in the original experimental instrument by using the electric mete to measured the liquid density and to im prove the equipment to measure the liquid density .The result was showed that it was not only enhanced the precision of the measurement ,but also realizes conveniently quickly to measure .
