摘　　要：介绍利用四象限模拟乘法器等构成质子进动信号模拟器来校准质子磁强计。此方法能以物理常数γ＇ｐ和频率计直接校准质子磁强计。校准的不确定度小于 １．４×１０～(－７)。可以取代使用替代法在弱磁场标准装置上校准质子磁强计。Calibration of Proton Magnetometer using the simulator of Proton signal, which is made from four quadrants multiplier, is introduced in this article. The method of calibration based on the physics constant γｐ and measurement of frequency.The uncertainty of this calibration, which can be substituted for standard of low magnetic field, is better then l.4× 10^-7.
