| 摘 要： | 本文研究了1938-1958年间,太阳γ及βγ黑子磁場区的3級与3~+級大耀斑的地磁效应。用相关及迴归分析法,計算了太阳赤緯、日軸方位角及耀斑的日面經緯度等因素对于磁扰的彭响。根据分析結果,繪出了日面地磁扰动等值图。利用水手2号飞船上量譜仪測出的太阳风速度和相应的地磁A_p指数,算出了相关关系,并用此和上述日面地磁扰动等值图配合,推算了在耀斑发生以后,太阳风的径向分量沿地球軌道的分布。参考文內各相应的曲线,可以約略估計出耀斑发生后地磁A_p指数的大小。

| Abstract: | The geomagnetic effects of solar flares of importance 3 and 3~+ in the sunspot regions of magnetic classes γ and β_γ during 1938-1958, are examined statistically according to the declination of the sun, the position angle of the sun's axis of rotation from the north point of the disk, and the heliographic coordinates of the flare. The results of correlation and regression analysis are drawn on the heliographic chart as isolines of geomagnetic disturbance. The data of the solar wind velocity, measured by the spectrometer on the spacecraft Mariner Ⅱ are made in correlation with the corresponding geomagnetic A_p index and they are in turn used with the isomagnetic chart mentioned above to estimate the distribution of the radial velocity of solar wind along the earth's orbit after the relevant eruptions. In addition, the A_p index following a flare thus far considered, can be estimated approximately by consulting the various curves given in the full text. |
