摘要
本文用1970－1995年的冕洞资料，分析了冕洞的分布规律，磁场极性的演化特征和冕洞的地磁效应，以及它们与太阳黑子周期的演化关系，得到了一些有意义的结论。特别指出赤道冕洞和极区冕洞具有相反的演化规律和不同的特征。
In this paper we use the data of coronal holes (CHs) ever since their systematicobservations (1970- 1995) t0 analyze their laws of distribution, the evolutionaryfeatues of magnetic fields and their relation with solar cycles. We have alsoinvestigated the geomagnetic effect of the CHs. Some valuable results have beenobtained. It is especially noted that the equatorial CHs and the polar ones exhibitdifferent rules of evolution. That of the equatorial CHk is basically consistent withsolar cycles, while that of the polar CHs is just the opposite.
