摘要
液体粘滞系数的测定是一项基础物理实验,影响此实验结果的因素较多,在实际操作中往往会存在误差较大的情况。通过改进实验仪器,对各个重要参数进行了多次规范的测量,并研究了各测量参数的相对误差传递,旨在找出减小误差的方法。
The measurement of the liquid viscocity coefficient is a basic physical experiment. The rather large percent error in this experiment is due to some factors. To solve the problem, we do re- fined experiments and use the error propagation tormula to study the transmission of errors caused by the important factors. The aim of this study is to find a way to decrease the error.
