In the image, one coronalhole appears near the top center of the sun while another one — a polar coronalhole — is visible near the bottom of the view.
在这个图片里，一个日冕出现太阳中心的顶部附近，而另一个与之相对的日冕，出现在视野的底部附近。

Energy balance models of the chromosphere-corona transition region are computed for a segment of coronalhole assuming a nonradial magnetic field geometry.
本文采用非径向磁流管位形的假设，计算了太阳冕洞网络部分的色球-日冕过渡区的能量平衡模型。

Notice also the north polar-crown filament, the trans-equatorial loops, and the coronalhole in the south-east (lower-right) corner of the image and the smaller one over the north pole .
