摘要
介绍了利用秒表测定液体密度的方法.该方法通过秒表测量漂浮在待测液体中做简谐运动的试管的运动周期,经计算即可得到待测液体的密度.与传统测定液体密度的实验相比,该方法设计巧妙,操作简单.
A method of measuring liquid density by stopwatch was designed.The harmonic motion period of a tube in liquid was tested by stopwatch.Then the density of the liquid was calculated.Compared with the traditional experiment of measuring liquid density,the improved method was cleverly designed and easy to operate.
