摘　　要：在电子束磁聚焦现象的理论基础上分析了利用磁聚焦法测量地磁场的可行性,并在电子束实验仪上测量地磁场的主要参量,结果表明,利用磁聚焦法测量地磁场实用有效,测量结果精确度较好。Based on the theory of magnetic focusing of the electron beam in the magnetic field,the feasibility of measuring geomagnetic field with the method of magnetic focusing is analyzed. The main parameters of geomagnetic field are measured using electron--ray instrument with this method. The result shows that the measuring geomagnetic field with the method of magnetic focusing is actable, and the accuracy is well.
