摘要After adding the data observed in the years from 1979 to 1982 to those obtained earlier (Ding et al., 1981), the authors re-examine the previous results and conclude: (1) The longitudinal distribution of spiral spots on the solar disc is generally the same as that of sunspot groups with areas of Sp ≥ 400, but their active longitudes seem to be more concentrated. (2). The distribution of spiral patterns in the southern and northern hemispheres shows that the differential rotation may be a fundamental solar dynamo for the formation of the spiral spots. (3) The statistical directions of the emerging twisted magnetic vectors in the active regions in the southern and northern hemispheres are synchronously inverse with a period of about two years. This period seems to be detected in other solar observations.
