This paper is a statistical analysis on the change of f,b,E,8, of E,8, and occurrence of three types E,8, with solar activity at Wuchang over the eleven—year period of 1970—1980. Correlation coefficients for R,max, and R,min, are 0.96 and 0.42 respectively, A discussion of the results has been made in terms of the theories of ionospheric absorption and of the wind shears and according to the point of view that the maximum ionization in the E,8, layers is closely dependent upon the maximum background ionization in the E region.
