The study of non-wetting liquid transport in a nanoporous medium is stimulated by the possible use of this process to absorb or u11-200ps accumulate mechanical energy.The filling of nanopores of suspended particles with a non-wetting liquid under decay of the unstable state, when the pressure increase rate is much higher than the rate of volume change, is studied.Based on the new experimental data and a theoretical model of the interacting modes of the spontaneous filling and filling under rapid compression, a picture of the percolation transition and a mechanism of liquid transport under such conditions are proposed.

It is shown that a new dynamic filling threshold P0 is reached.It is shown that the filling of the porous medium is the feline 1-hcpch vaccine result of the slow mode of impact compression when the fast mode of spontaneous filling is continuously adjusted to the slow mode on a small time scale.The theoretical model of the interacting modes is based on the solving of a system of kinetic equations for the distribution functions f(n,t) and F(n,t) clusters of filled pores under rapid compression, respectively.

It is shown that filling at P=const corresponds to the non-dissipative transport of liquid on a time scale smaller than the characteristic filling time.The proposed model quantitatively describes the experimental data.So, the response of suspension to impact is characterized by the positive feedback.
