一、核磁共振测量磁场的原理 在磁场的精密测量中,核磁共振法是一种精度最高、量程最宽、探头不大的好方法[1].它是以核磁共振理论与实验技术做为基础[2-4].核磁共振条件为 f=(γ/2π)H0(1)对于某种特定的原子核来说,γ是一个常数.因此,核磁共振频率f与静磁场强度H0是成正比的 First, the principle of nuclear magnetic resonance measurement of magnetic field Precision measurement of the magnetic field, nuclear magnetic resonance method is a high precision, widest range, the probe is not a good way [1]. It is based on NMR theory and experimental techniques as a basis [2-4] The condition of the nuclear magnetic resonance is f = (γ / 2π) H0 (1) For a given nucleus, γ is a constant, and therefore the nuclear magnetic resonance frequency f is proportional to the static magnetic field strength H0
