Abstract

A time history of the parameters of acoustic emissions (AEs) in the process of a capillary liquid flowing in a porous medium is considered. The application of exponentially damping process to the impregnation processes is experimentally established. A method for testing the impregnation depth and completeness of materials based on AE measurement data is proposed.
