摘要: This paper provides information on a self-consistent model of an anomalously slow relaxation nonwetting liquid–nanoporous medium systems with random size distribution pores, which introduces changes in interaction between local liquid cluster configurations the process outflow from porous medium. A equation was deduced, solution determines functional connection filling degree or time 𝜃(t). It is shown that presented as decay interacting metastable configurations, initialized by thermal fluctuations. As increments, acceleration takes place subsequent avalanche fluid medium, connected decrease configurations. The dependence fraction volume remaining power law 𝜃(t) ∼ t−α(T,t). for system water–L23 at initial stage range 10s < t 103s, index assumes constant value α ≈const(T), while following and increase parameter α(T,t) are observed.
