日冕物质抛射的观测性质

综述日冕物质抛射的观测和持性，简短的前言之后，给出ＣＭＥ的发现经过及统计特性，着重介绍ＣＭＥ与其他种类太阳活动的相关。然后介绍ＣＭＥ的一般特性，包括可能与ＣＭＥ相关的一些物理过程的观测特性。初步结论是：ＣＭＥ是一种演变中的磁结构现象。

Observational Properties of the Coronal Mass Ejection

In this paper the observational properties of the coronal mass ejection(CME) are summarized. After a brief introduction, the discovery and the statistic properties of CMEs are given,with an emphasis on the correlations of CMEs to other kinds of solar activity. Afterwards, their general properties are given, including the observational properties of some physical processes which are possibly relavant to CMEs. A preliminary conclusion is: CMEs are phenomena of evolving magnetic structures(EMSs). CMEs may be associated with disturbance in the magnetic structure in the solar atmosphere which can lead to a destabilization. The disturbance may also induce flares or prominence eruptions if the conditions are right for such an event. Further observation will be able to find the direct cause of CME.
