The mathematical and numerical model of probe problems in the indignant zone of the companion is developed. Initial and boundary conditions for probe problems are received from predesigns of parametres of the indignant zone of the companion which is flowed round by a stream arefied plasma. Influence of the form of functions of distribution and other features of area of an arrangement of a probe on results of processing of probe experiments is investigated. It is established that the error connected with neglect by these features, can lead to processing errors зондовых experiments of 50 % and more.
