【Abstract】 This paper gives an introduction to the concepts of Indeterminacy Type A,Indeterminacy Type B, and indeterminacy by extension in measurement for experimental purposes, then goes on to present a simplified method to analyze and describe experimental errors especially in potentiometer a measurements.Both the analysis and the description are proved to be well within high confidence probability and claim many advantages as a necessity for college physics experimentation teaching.更多还原
