Аннотация

In given work the longitudinal acoustic waves reflection from boundary of a solid body with dissipative liquid theoretically is considered. The essential dependence of factor of signal reflection and its phase from factor of absorption of ultrasound in dissipative medium is shown. The experimental confirmation of conclusions of the theory is carried out by consideration of reflection of an acoustic pulse from the boundary of plexiglass - ероху pitch while the last is loaded, shown essential reduction of reflection factor and of acoustic pulse duration while ероху pitch is hardening.
