| 摘 要： | 对成都地磁台两年多(2002~2004年)的地磁总强度数字与模拟观资料进行了对比分析,结果表明:由于数字观测资料与模拟观测资料取数的个数不同,两者的曲线变化形态不同。模拟地磁总强度的形态为近直线型,而数字化地磁总强度则有显著的日动态变化。但数字观测资料经过平均处理后产生的日均值与模拟观测日值大致相同。据现有资料,数字化地磁总强度的映震能力优于模拟地磁总强度。

| Abstract: | The digital data of the geomagnetic total intensity observed more than 2 years and the imitative one are compared with each other.Our results show that there are some differences between them since their intervals of the collecting signal sample are not same.The change shapes of the imitative data of the geomagnetic total intensity shows a straight line and the one of the digital data appears a daily change.But the daily average values are same.The digital observing data is batter than the imitative one. |
