Abstract :
Summary form only given. The study of equilibrium properties and the phenomenon of transference in strongly interacting multicomponent media is an actual problem of low-temperature plasma physics. It is most difficult to solve this problem for the multiparticle systems with different potentials of interaction. A review of the results of theoretical research concerning thermodynamical and kinetic properties of non-ideal low-temperature plasmas of various substances carried out by the authors has been presented in this paper. Accounting for the formation of quasiconnected electron-ion states in continuous spectrum and presence of ion flame in a multielectron ion showed the effect of Coulomb´s non-ideality with increasing of plasma parameter /spl Gamma/. The contribution of atom-atom and ion-atom interactions to thermodynamical functions of an atom plasma, which also lends to attenuation of Debye´s correlations, has been investigated. In the low-temperature region T/spl Lt/D (D is the energy of molecule dissociation) the properties of multicomponent systems with accounting of 2- and 3-atomic molecules and molecular ion formation were studied. The wide-scale calculation of thermodynamical functions and plasma composition for various types of the substances in the wide field of substance diagram of states were carried out taking into consideration two and three-particle interactions.
