Abstract:

For the course “ error theory and data processing ”, which is highly theoretical and has many calculation formulas, while traditional teaching focuses on theory and ignores practical problems, based on Matlab APP(Application) Designer, a comprehensive experimental system APP is designed. The basic concepts such as random error, systematic error and gross error and typical algorithms such as least square fitting are realized and visualized respectively. Based on the actual engineering data of ground nuclear magnetic resonance, the methods for removing systematic errors and gross errors are presented. This comprehensive experimental platform cultivates students ' application ability and completes the organic combination of scientific research and teaching. The experimental platform is convenient for students to understand and master abstract concepts, and improve students ' interest in learning.

Key words: error theory and data processing, least square fitting, design of experimental
