冕洞

从而说明这种阿尔文波的加热似乎是引起温度、密度偏低的大气（例如冕洞大气）在过渡区中温度陡升的重要原因。

It is suggested that Alfven wave heating may be a dominant energy source causing the steep increase of temperature in the atmosphere of a coronal hole .

上面的图像是由X射线望远镜拍摄到的，如日出（？），冕洞之所以表现为黑暗，是因为炙热的发光气体将填补这些已蔓延的太阳风。

In images taken by X-ray telescopes , such as the one Hinode uses , coronal holes appear dark because the hot glowing gas which would otherwise fill them has spilled out in the solar wind .

根据这些量的分布特点，认为日球基本参数T、N和V的冕洞周变化，可以用冕洞磁场的非径向因子a值，随黑子活动的下降而变小来解释。

It is found that coronal-hole cycle variations of some basic heliospheric parameters , such as V , T and N can be explained by the decrease of the nonradial factor a of the magnetic field in the coronal hole as solar activity is decreased .

继而分析1997~2003年所有爆发在冕洞边缘的快速晕状CME，发现源区离冕洞距离小于0.2Rs（太阳半径）的CME均没有引起大的SEP事件。

Then by investigating all fast halo CMEs close to CHs from 1997 to 2003 , it is found that none of the CMEs produced a major SEP event when the surface distance between the CME and coronal holes is less than 0.2R-s .

在冕洞大气中，由于波动量的淀积而产生的对流能损耗也是重要的，在过渡区底部650km以上，对流能损耗逐渐超过辐射损耗。

In the transition region at the heights greater than 650 km above the base of the transition region the convection energy losses may gradually exceed the radiation energy losses .

着重对澳大利亚FLEURS天文台太阳扇形射束东西扫描资料进行了分析，并据此采用计算机处理系统建立起日面上冕洞位置逐日运行图。

The data obtained by the solar fanlike beam scan of Fleurs Observatory in Australia has been emphatically analyzed . Based on the analysis , the day by day moving maps of the locations of coronal holes on the solar surface has been showed by using computer processing system .
