| 摘 要： | 主要介绍晕状日冕物质抛射（halo CMEs)的产生机制，包括向量磁场演化是怎样触发halo CMEa的：halo CME与耀斑，暗条活动的相互关系怎样，是否有规律可循，暗条爆发，耀斑等活动现象是如何相互联系的，halo CME事件是由一个活动区域或一个活动事件驱动物，还是多个活动区或多个活动事件相互作用的结果，给出两个halo CME的日面起源的观测例证，提出相反极笥的磁场对消是CME日面源区磁场演化的主要特征。

| Abstract: | This paper mechanisms of halo coronal mass ejections (halo CMEs) have been mainly presented, including how the evolution of vector magnetic field triggers the halo CMEs? what is the relation between the halo CME, and the activities of flares and filaments? is there any pattern available? how the filament explosion and flare actvity are related to each other? Is the halo CME event driven by either an activity region or a single activity event, or resulted from interaction among either different activity regions or among different activity events. Two observational evidences to the solar surface origin of halo CME are demonstrated. It is suggested the cancenation of two opposite magnetic flux is the main characteristics of the evolution of magnetic fields in the solar surface areas. |
