引言在地球物理工作中对测量垂直磁场方面进行了大量工作,近来一种测定总磁场的仪器已经发明而且获得了相当的成功,这种仪器的操作较垂直磁力仪简单而迅速,而它的精确度却仍能与垂直磁力仪中最好的一样,因为此仪器测定的是总磁场;读数完全不依赖于方位和水平位置。仪器的读数给出的是磁异常在地磁场方向的分
INTRODUCTION Much work has been done in geophysical work on the measurement of vertical magnetic fields. Recently, an instrument for determining the total magnetic field has been invented and has been quite successful. The operation of this instrument is simpler and faster than that of a perpendicular magnetometer and its accuracy The degree is still the same as in the vertical magnetometer because the instrument measures the total magnetic field; the readings are completely independent of the azimuth and horizontal position. The readings of the instrument give the points of magnetic anomaly in the direction of the geomagnetic field
