چکیده انگلیسی
By using the solar magnetic field data of Wilcox Observatory from 1975 to 2010, the short-time periodicities of solar mean magnetic fields during solar maximum and minimum years are analyzed. The results reveal that the solar magnetic fields mainly exhibit the approximate periods of 9 d, 13 d, and 27 d. During maximal solar activity the period about 27 d is most conspicuous, while during minimal solar activity the most evident period is approximately 13.5 d (except the solar minimum in the years 1984-1986). These results imply that solar active regions exhibit evidently different distributions in the periods of maxima and minima of solar activity.
