For determining the n onstationary picture of the ionization d ensity the problem (1), (3) is solved by nonexplicit differential scheme f o r a (Danov and Kartalev,1986). In such a n a p p r o a c h the step along t, i.e. A t , m a y be of the order of 10 в, and the step along z- i z - a b o u t 2 km.

R e s u l t s . In the numerical s olving of the considered problem the models are chosen for d i s t r ibution of temperature of the neutral component (model MSIS) and the mass of the neutral component (Clark et al.,1970). Using these data one determines p Q and p0 fr o m equatio n (5) of the Appendix. The value of T 120 is taken 355°K..
