| Abstract: | The error theory based on entropy concept and its application are illustrated. The uncertainty for entropy method about B class and A class of knifepoint position is analyzed. The error tracing is applied in two typical process using entropy methods, and the dynamic entropy value of knifepoint position is simulated. The results show that using entropy method for error tracing is near to the fact, which means this method to be feasible and worthwhile. |
