摘要
本文根据1987年1月—1989年11月期间,2cm、3.4cm、6cm、10.7cm和21.2cm五个波段每日总辐射流量与日面上占主导地位的活动区黑子视面积之间的关系,对第22周上升段若干大活动区的射电缓变成分的统计特性进行了分析研究,发现有几个大活动区在日面时S-Ay图上处在平均曲线之下,当黑子面积增加时,射电流量的增加并不明显。
Based on the relations between the apparent area of major sunspots on the solar disk and the daily total flux at the wavelengths 2cm, 3.4cm, 6cm, 10.7cm and 21.2 cm for the period of January 1987 to November 1989, the statistical features of solar radio slow variation component (SVC) for some major active regions during the rising stage of the cycle 22 are analysed. It is found that several large active regions were located below the average curve in the S-Ay diagram, and the increase in radio flux density was insignificant as compared with the corresponding increase in the sunspot area.
