摘　　要：We reconstruct the developing history of solar 10.7 cm radio flux （F10.7） since 1848, based on the yearly sunspot number and the variations. A relationship between the maximum and the linear regression slope of the first 3 years starting from minimum of the solar cycle is considered. We put forward a method of predicting the maximum of F10.7 by means of the slope-maximum relationship. Running tests for cycles 19 to 23 indicate that the method can properly predict the peak of F10.7.We reconstruct the developing history of solar 10.7 cm radio flux （F10.7） since 1848, based on the yearly sunspot number and the variations.
