註釋A model of the quiet ionosphere in the altitude range 100 to 500 km for various conditions of solar activity is constructed. In order to carry out this program, a model atmosphere, i.e., profiles of temperature density, pressure, number density of the various constituents, and scale height, based on rocket and satellite measurements and on models developed by other investigators, is also developed. From the model atmosphere and from measurements of the intensities of solar ionizing radiations, ionization rate profiles are computed. Electron loss and diffusion processes and their associated rate constants are also treated, and the results are substituted into appropriately simplified forms of the continuity equation; the solutions yield the ionospheric model. E- and F-region irregularities are also discussed, and a model of electron collision frequencies in the altitude range 100 to 500 km is presented. (Author).
