    The complex electrodynamic analysis holding for dipole aerials in a wide range of the modification of inpur parameters, in that number parameters of excitation sources, on the base of the solution of integral equations with singular nuclei is the aim of the paper. As a result the new high effective munerical-analytical method for the solution of integral equations of dipole aerials has been suggested. The structure of exact integral equations of cylindrical, belt vibrators and also a belt vibrator near a screen has been investigated. The integral equations obtained have been reduced to infinite systems of algebraic equations of the second kind. The numerical-analytical method has been suggested for the solution of these equations. The system of integral-differential equations has been obtained. Singular operators of the non-axially symmetric excitation have been investigated. Algorithms and programs have been developed on the base of the base of the numerical-analytical method suggested. The complex electrodynamic analysis of dipole aerial characteristics for a wide range of vibrator parameters with various excitation methods has been heldAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

    The object of investigation: the gasophase pyrolytic polymerization, n-xylilene, n-cyclophane, poly-n-xylilene, copolimerization. The purpose of the work: the investigation of modifying by the different methods of the thin polymer films on the base of n-xylilene, study of the structure and permeability of the new polymers. For the first time, the copolymers of n-xylilene with vinyl monomers and fulleren C60 have been synthesized in the form of the thin films. The composite gasoseparation polymer membrane has been developed for concentration of the carbonic acid gas from the gaseous mixtures. Two Authorised Certificates for the method of receiving the polymer membranes have been obtained. The field of application: separation of the gaseous mixturesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
