| 摘 要： | 综合APIA、HONOLULU、PAMATAI 3个地磁台三分量的11年周期变化的形态后，可定性地提出该变化源于内场。如内源为核幔边界的电涡流，则其中心点应位于3台之间。

| Abstract: | Based on the feature of the variations of the 11-year-period for the three components X,Y and Z of APIA,HONOLULU and PAMATAI observatories,we can conclude that the 11-year-variation in this region is of internal.If the internal source is an electric vortex existed at the core-mantle boundary,the vortex center should be located in the triangle area bounded by the three observatories. |
