日冕物质抛射为理解日冕能量释放和转换的物理学提供了一个途径。虽然人们普遍认为，为CME提供动力所需的能量包含在喷发前的日冕磁场中，但该磁场在CME前的状态以及导致磁能释放的条件仍然不完全清楚。最近的研究指出，这是共同的许多，如果不是所有的，CME事件的各种现象，这表明可能有可识别的特征的前CME日冕的信号即将爆发。然而，确定这些现象是否是必要的，甚至是充分的，还有待实现。在本文中，我们试图总结的状态，太阳日冕和它的演变，在建立一个CME。
Coronal mass ejections provide a gateway to understanding the physics of energy release and conversion in the solar corona. While it is generally accepted that the energy required to power a CME is contained in the pre-eruption coronal magnetic field, the pre-CME state of that field and the conditions leading up to the release of the magnetic energy are still not entirely clear. Recent studies point to various phenomena which are common to many, if not all, CME events, suggesting that there may be identifiable characteristics of the pre-CME corona which signal the impending eruption. However, determining whether these phenomena are necessary or even sufficient has yet to be achieved. In this paper we attempt to summarize the state of the solar corona and its evolution in the build up to a CME.
