摘　　要：文章介绍的质子磁力仪的基本原因及使用,并用质子磁力仪测量了质子在地磁场作用下的进动频率,弛豫时间和峰峰值电压,并计算了不确定度。In this paper, we introduced the principle and the method of application of the proton precession magnetometer. The procession frequency, relaxation time and the peak to peak value voltage were measured by the proton precession magnetometer. The Earth magnetic field intensity and uncertainty were calculated.

关 键 词：质子自旋 进动频率 地磁场
