| Abstract: | 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. |
