初步发现：在F层高度上，在Pc3&5频段，电离层离子速度与地磁微脉动H分量有着良好的相关。
It is found that there is a good correlation between ion velocity and Pc 3-5 pulsations .

我们还讨论了磁声重波与地磁微脉动之间的关系，沿着重力场方向向下传播的磁声重波，可能直接引起赤道附近的Pc1磁脉动。
The magneto-acoustic-gravity waves propagating downwards along the direction of gravitational field may produce directly the PC 1 magnetic pulsation near the equator .

结果表明：选用适当的小波，采取合适的阈值选择规则和比例调整方式，可以很好地实现对地磁微脉动信号的消噪处理。
Results show that heuristic SURE threshold and fixed form threshold are two good threshold selection rule in Pc type geomagnetic pulsations'noise elimination .
