Abstract
Spread-F is an important ionosphere pheonomenon and it has much effect on radio wave propogation. Taking magnetic inclination and declination into consideration, a theoretical model is deduced for the linear growth-rate of spread-F. It is a generalization of the earlier equatorial model and a relatively complete description of the spread-F pheonomenon. This theory shows that the magnetic configuration, i.e. the magnetic strength, inclination and declination, affects the occurrence rate greatly, which forms some regional distribution characteristics of the spread-F.
