摘要
根据资料分析了中国低纬地区地磁场Ｈ分量的静日变化规律。结果表明，Ｈ分量日变幅在中午１２点左右达到最大值，在夜间达到最小值，而且，这种受赤道电射流影响的现象还随着季节和太阳活动变化而变化。
In this paper,the authors analyse quiet-day geomagnetic variation regularity ofhorizontal geomagnetic vector H at low latitudes of China. The results indicate that thedaily range of H reaches a maximum value at about twelve o’clock at noon,and reachesa minimum value at night.The phenomenon which is influenced by equatorial electrojetcurrents varvs with different seasonal and solar action.
