Phenomenon of inversion of the stable states of gas-fluid- "heavy" particles system in the vibrating vessel

On the basis od vibrational mechanics approach and method of direct separation of motions the behaviour of gas-fluid-solid "heavy" particles system in a vibrating vessel is considered. The analysis of the received nonlinear equation of slow motions of a particle in the field of standing wave has allowed to come to rather simple conditions of dipping gas bulbs in to the fluid and floating heavier particles.In these instances the system tends to a maximum of potential energy as to s steady state.Pecular "vibrating unstability" of stable without vibration and separate state of gas-fluid and fluid-heavy particles systems in the field of gravity ahs been revealed.The "slow" self-oscillating phenomena in system have been described. The results are in good agreement with experimental data of the authors and other researchers.
