摘要
塞曼效应实验中谱线环的直径会随着磁场的强弱而变化,可以利用此现象测量磁场.本文导出了磁场测量公式,通过实际测量,发现了磁场测量误差的规律,设计了误差传递模型来模拟和论证了这一规律,所得到的结论,可以指导磁场测量的方法,提高测量的精度.
In the Zeeman effect experiment, the diameter of the spectral line ring varies with the strength of the magnetic field. This phenomenon can be used to measure the magnetic field. In this paper, the magnetic field measurement formula is deduced, the law of magnetic field measurement error is found through practical measurement, and the error propagation model is designed to simulate and demonstrate this rule, and the conclusions obtained can guide the method of magnetic field measurement and improve the precision of measurement.
