摘　　要：根据磁暴报告,得出昌黎地磁台与同一纬度各台垂直分量△Z的最大幅度差值从几nT到60多nT的差异,初步探讨了昌黎地磁台及其地域地磁变化异常现象。Based on the report of magnetic storm, the maximum difference of vertical component △Z between Changli Geomagnetic Station and the other stations at the same latitude is from a few nT to over 60nT. This phenomenon is discussed here.

关 键 词：地磁场 磁暴 垂直分量 地磁变化异常
