误差理论与数据处理课程综合性实验平台设计

Design of Comprehensive Experimental Platform for Error Theory and Data Processing

针对“误差理论与数据处理”课程理论性强,计算公式多,而传统教学中存在重理论、轻实践问题,基于Matlab APP(Application) Designer,设计了综合性实验系统APP。分别实现了随机误差、系统误差和粗大误差等基本概念和最小二乘拟合等典型算法的快速实现和可视化。同时,依托“地面核磁共振”实际工程数据,设计了系统误差和粗大误差的去除方法。该综合性实验平台不仅能培养学生的应用能力,还能使科研与教学有机结合,便于学生理解和掌握抽象概念,提高学生的学习兴趣。

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.
