摘　　要：通过采用DZZX-1型电子自旋共振仪,借助于计算机辅助技术,每月月初对贵阳市乌当区地磁场大小进行实验测量。结果显示,一年内的平均磁场大小为(0.48±0.02)×10^(-4)T,其中垂直分量与水平分量分别为(0.34±0.03)×10^(-4)T与(0.33±0.01)×10^(-4)T。测量地一年中的地磁场起伏程度较小,大体上呈现出稳定性。据此拓展了实验相关的教学思考,在近代物理实验教学中,根据实验特征,注重相应的探索性和应用性。The local geomagnetic field is measured experimentally using the DZZX-1 electronic spin resonance instrument and computer technology at the beginning of each month.The experiment result shows that this magnitude of geomagnetic field is about(0.48±0.02)×10^(-4) T during one year,with(0.34±0.03)×10^(-4) T and(0.33±0.01)×10^(-4) T on the horizontal and vertical components,respectively.The geomagnetic field fluctuates less in December of the year,generally presenting stability.Based on this,the teaching thinking related to experiments has been expanded.In view of the characteristics of experiments,attention should be paid to the exploration and application in modern physics experiment teaching.
