【摘要】 研究了冕洞面积与绿日冕亮度在太阳活动 2 0 ,2 1,2 2周中的一些关系 :1)冕洞总面积的最大值、最小值出现在绿日冕亮度差率为一些定值处 ;2 )当冕洞总面积是最大或最小值时 ,绿日冕亮度减小为 0 .31～ 0 .61相对强度单位或 0 .10～ 0 .11相对强度单位更多还原

【Abstract】 The some relationships between area of coronal holes and green coronal brightness were investigated during solar active cycles 20,21,22: 1)the maximum and the minimum of total area of coronal holes appeared at the some values in the rate of green coronal brightnes;2)when total area of coronal holes was the maximum or the minimum,the green coronal brightness decreased about 0 31~0 61 or 0 10~0 11 relative intensity unit.更多还原
