Abstract
The effect is theoretically studied of nonreciprocity of interparticle forces on the energy exchange between the linear chain of dust particles and the ambient medium. It is shown that the energy exchange between the dust component and ion flow is important. When approaching the threshold for developing the instability of coupled waves, the considerable deviation occurs of the kinetic energy distribution from the law of equipartition of kinetic energy over degrees of freedom. In the case of inhomogeneous heating of the chain, the heat conduction coefficient does not depend on the number of particles and is determined by the parameters of the ambient plasma
