摘　　要：介绍了采用微差法进行测量的双线圈磁强计．证明了在用双旋转线圈感应测量直流恒定磁场时，采用微差法对被测磁感应强度进行测量，能利用本身测量准确度并不高的测量仪器，获得高的测量准确度．The micro differential method can be used to measure the magnetic intensity when a constant magnetic field is tested through induction from a di rotating coil. Based on the method, an excellent accuracy can be obtained by the ordinary instrument. The accuracy of a well used single coil magnetometer is only within 0.1%￣1%, but the one of the reported magnetometer can reach 0.01%￣0.1%.
