摘　　要：地磁场水平分量的测量在很多领域占重要地位。地磁场的形成是由于地电流,地球表面不同地点的磁场强度不同。介绍了用正切电流计和冲击电流计测量地磁场水平分量的两种方法,得到锦州地区当时的地磁场水平分量的大小,并分析了产生误差的原因。The measurement of horizontal component of the geomagnetic field occupies the important position in a lot of fields. The forming of the geomagnetic field dues to the ground electric current, so the magnetic field of different places on the earth surface is different in intensity. In this paper, the author intruduced two methods of measuring the horizontal component of the geomagnetic field （by using the tangent galvanometer and the ballistic galvanometer）, obtained the value of horizontal component of the geomagnetic field in Jinzhou at that time, and analyzed the reason of causing the difference.
