The Possible Contribution of The Coronal Hole Periphral Structures to the Coronal Mass Ejections

The probable relation among the 140 Coronal Mass Ejections (CMEs)events which obtained from satellite SMM in 1980、1984、1989 and the periphral structures of coronal holes、flares and eruption prominence events is analysed in this paper.The result shown that the relation between the CME and the periphral structures of coronal holes is most close. The CME and equatorial coronal holes have a sy nchronous long-range evolutionary relation. From this point of view it is no ted that the possible contribution of the coronal hole periphral structures to the CME can not be ignored.
