摘要
通过测量乒乓球转动惯量,介绍了间接测量中的不确定度传递和计算。研究发现乒乓球的质量是影响其转动惯量的主要因素,而内、外直径则是影响较小因素。
It describes how to calculate measurement uncertainties using as a practical example the assessment of the rotational inertia of the spherical shell of the ping-pong balls. The masses of the empty ping-pong balls are the influence of the rotational inertia of the ping-pong ball major factor,internal and external diameter less influence factors.
