| Abstract: | In the experiment of measuring Young＇s elasticity modulus of metal filament by using tensile method, generally there are a number of ways to measure the results of the evaluation of uncertainty. This paper mainly discusses the simplified evaluation of uncertainty which processed by method of successive minus in teaching ： measuring the volume of a single experiment in accordance with the terms of the specific estimates, repeated measurement using synthetic method. |
