The solar atmosphere above that consists of the photosphere , chromosphere , a transition region and the corona .

太阳大气则由光球层、色球层、过渡区和日冕组成。

This eclipse took place during a maximum of a sunspot cycle , and the image is processed to show not only the corona but also the chromosphere and the prominences

日食发生在太阳黑子周期的高峰期，经过处理的图像不仅显示了日冕，而且显示了色球层和日珥。

It is difficult to photograph the actual chromosphere .

拍摄实际的色球层很困难。

As spicules measuring in the tens of thousands of degrees kelvins rise from the chromosphere , the researchers noticed , patches of the corona above flare up at one million to two million degrees .

研究人员注意到，从色球层产生的日珥能达到上万度，日冕上的某些部分甚至能达到一百万至两百万度。

Spicules , which are short-lived fountains of plasma shooting up from the sun 's chromosphere , or lower atmosphere , seem to play a role in heating the corona to searing temperatures at millions of degrees kelvins , investigators have found .

研究人员发现，日珥，这种在太阳色球层短暂的等离子气体喷发，在对日冕的加热中起到重要作用。
