大黑子群对太阳总辐照度的影响

本文用云南天文台在第２２周太阳活动峰年期间拍摄到的大太阳黑子群照相资料，太阳黑子目视描述资料，以及Ｎｉｍｂｕｓ—７卫星上辐射计测量的太阳总辐照度，分别计算了太阳总辐射照度与大黑子群的本影视面积，大黑子群全群视面积和日面上全部黑子的总视面积的相关系数。结果表明，太阳总辐射照度与这三种视面积均存在强的负相关。其中与大黑子群本影视面积的相关最强，其次是与全群视面积的相关，最后是与日面上全部黑子的总视面积的相关。并对以上结果和其它有关结果进行了分析和讨论。

Effect of Large Sunspot Group on Solar Total Irradiance

In the paper the correlation coefficient between the solar total irradiance and various kinds of projected areas of sunspots, the projected area of umbra of large sunspot group, the projected area of large sunspot group, the projected area of all the sunspots on the disk per day are calculated respectively by means of the data from the large sunspot groups photographed with 26 cm Vacuum Solar Telescope, the data from the sunspot groups drawn at the Yunnan Observatory and the solar total irradiance measured by the radiator on Nimbus-7 during the pened of the 22nd solar maximum years. As a result these correlation coefficients successively are r1=-0.89, r2=-0.77,r3=-0.59. The brief explanation is given to these results and the other relevant result is also discussed.
