To the theory of electric probes in a transition collisional regime

Method for the calculation of parameter distributions of partially ionized gas in the neighbourhood of electric probes of spherical and cylindrical configurations at the presence of charged component collisions with neutral background is suggested. Probe characteristics are calculated at different Knudsen numbers. The dependence of error in determining the probe characteristic on the number of ''large particles'' is investigated. It results from the calculations that with the increase of the Knudsen number the probe characteristics asymptotically tend to the known accurate solution that proves correctness of the method
