| Abstract: | The paper analyzed how to report the results of physical measurements based on the experiment of measuring viscosity coefficient of liquid by falling-ball method.The calculation method for two types of uncertainty is discussed.The total uncertainty of directly repeated measuring result is expressed by type A and type B of uncertainty through ＂square sum root＂ method.The total uncertainty of measuring result u=（uA2＋uB2）～（1/2） can be obtained. |
| Keywords: | uncertainty degree falling-ball method viscosity coefficient |
