一、引言质子磁力仪是利用核磁共振感应法测量弱磁场强度绝对值的一种重要观测仪器,它具有测量精度高,温度稳定性好,无零点漂移等许多优点,广泛应用于地质、矿产、地震等生产、科研部门。但长期以来,该仪器操作方法没有多大改进,至今仍处于人工手动 I. INTRODUCTION The proton magnetometer is an important observation instrument for measuring the absolute value of the weak magnetic field intensity by using the nuclear magnetic induction method. It has the advantages of high measurement accuracy, good temperature stability and zero drift. It is widely used in geological, mineral, Earthquake and other production, research departments. However, for a long time, the method of operation of the instrument has not greatly improved and is still under manual operation
