الملخص EN

In this study, the motions of slow electrons in air and nitrogen with its mixtures are studies by details.

We solved numerically Boltzmann transport equation to calculate the parameters E, Vd and D / m have been possible to deduce expression empirical formula from which may be derived the drift velocity, collisional frequencies, electronic temperature and mean energy loss per collision.

These results applied to the ionosphere allow electronic collisional frequencies to be ready found in the ionosphere below 94 km, from the pressure of the air.

The collision cross-sections of the molecules of air and nitrogen when the electronics temperature is less than about 2600°K.

The addition results are presented for electrons drifting through air in a steady state of motion under the action of the electric field, such as, KT, U, Q, Q0, ω, Ω / P, h, hKT, and W/D for both Maxwell and Druyvesteyn distribution laws.

These parameters are graphically as functions for their variables.

The results appeared excellent agreements with the experiments and theoretical data.
