日冕物质抛射

摘要

The recent progress on the coronal mass ejections (CMEs), including observational results obtained by Yohkoh, SOHO, WIND, Ulysses, Geotail and POLAR, are presented. The relations between CMEs and solar activities, interplanetary disturbances as well as geospace environmental variations are investigated. Some typical theoretical models and numerical simulation results on the formation mechanism and propagating process of CMEs are described.Finally, some noticeable problems for future research are posed.%评述了近几年来日冕物质抛射研究的新进展，包括Yohkoh、SOHO、WIND、Ulysses、Geotail和POLAR等飞船最近取得的观测结果，并由典型事件探讨日冕物质抛射与太阳活动、行星际扰动和地球空间环境变化之间的关系。进而介绍日冕物质抛射形成机制和传播过程的主要理论模型和数值模拟结果，提出今后日冕物质抛射研究中一些值得注意的问题。
